一种电力线相别识别方法与装置 A power line relative to other identification method and apparatus

技术领域 FIELD

[0001] 本发明涉及电力系统领域,更具体的说,涉及一种电力线相别识别方法与装置。 [0001] The present invention relates to the field of power systems and, more particularly, relates to a power line relative to other identification method and apparatus.

背景技术 BACKGROUND

[0002] 在配电台区,变压器担负着配电和送电的重要任务,而三相负荷的平衡关系到变压器供电的可靠性、稳定性和变压器供电的损耗率。 [0002] In the zone with the radio, charged with the important task of transformers and power transmission and distribution, and the balance between the three-phase loads to the transformer power supply reliability, stability and power transformer loss rate. 为了提高配电利用率,需要将负载较重相上的一些用电户移到负载较轻的另外一相上进行供电,以平衡三相的负荷。 In order to improve distribution efficiency, you need to load some of the heavier phase on household electricity supply power to move the load lighter on another phase, balanced three-phase load. 所以,这就需要准确判断负载较重相上的用电户所在的相位。 So, which requires the user to accurately determine the phase electricity with heavier load on the location.

[0003]目前,存在两种用于判断电力线相别识别的台区识别仪,一种利用脉冲电流原理,在被测节点相上发送脉冲电流,在与被测节点同一相上的配电侧的接收节点接收脉冲信号,从而判断出被测节点的相别信息的台区识别仪;另外一种利用低压载波检测原理,在被测节点相上发送载波信号,在与被测节点同一相上的配电侧的接收节点接收载波信号,从而判断出被测节点的相别信息的台区识别仪。 [0003] Currently, there is a distribution side on the same node under test is used to determine the phase of the two-phase power lines do not recognize Taiwan area identification device, a pulsed current theory on the measured phase node sends a pulse current, The receiving node receives the pulse signal, and determines that the measured node relative to other identification device information of the stage area; another carrier detection principle by a low pressure, the measured phase node on the transmission carrier signal, at the same phase and the measured node the receiving node receives the distribution side of the carrier signal, to determine the stage area relative to other identification device information of the node under test.

[0004] 然而,这两种台区识别仪的实现原理都是在同一相上进行被测节点检测信号发送、传输和接收,根据配电侧的接收节点是否成功接收到被测节点检测信号来判断相别信息。 [0004] However, realization of the principle of these two sets of identification device region are in the same phase were measured on the detected signal transmission node, the transmission and reception, the receiving node based on whether the distribution side of the nodes successfully received the detection signal measured Do not judge the phase information. 但不同相上的被测节点检测信号和配电侧的接收节点无法完成接收,因此当某一相上干扰或者负载特别大时,被测节点检测信号在传输过程中发生串相,配电侧的接收节点无法接收被测节点检测信号,从而不能正确地识别电力线的相别。 However, the measured detection signal and the node receiving node side of the distribution of different phases can not be completed on the reception, so that when a particularly large load or interference on one phase, the phase node under test string detection signal is generated during transmission, power distribution side The receiving node can not receive the detection signal under test node, and thus can not correctly identify relative to other power line.

具体实施方式 DETAILED DESCRIPTION

[0051 ] 下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。 [0051] The following example in conjunction with the accompanying drawings of the present application embodiment, be clear that the present application example of the technical implementation of the program, fully described, obviously, the described embodiments are merely part of embodiments of the present application, but not all embodiments cases. 基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。 Based on the embodiments in the present application, all the other embodiments by those of ordinary skill in no creative efforts made under the obtained, are within the scope of protection of the present application.

[0052] 一个实施例 [0052] An embodiment

[0053] 请参见图1,其示出了本申请提供的一种电力线相别识别方法的流程示意图,该方法包括以下步骤: [0053] See Figure 1, which shows a schematic flow diagram of a power line provided herein relative to other identification methods, the method comprising the steps of:

[0054] SlOl :接收被测节点发送的相别识别请求。 [0054] SlOl: the receiving node sends the measured phase do not recognize the request.

[0055] 其中,相别识别请求在被测节点检测到自身所在电力线上传输的电力信号处于过零点时从被测节点发送,且相别识别请求中携带有帧数据报文。 [0055] which do not recognize the request in the test phase node detects transmission power line itself is located at the zero crossing of the power signal is sent from the test node, and do not identify with the request carries a frame of data packets.

[0056] 在本实施例中,电力信号选用低压电力线网络中的50Hz工频信号,其周期T=20ms。 [0056] In this embodiment, the power signal selection of low voltage power line networks 50Hz frequency signal with a period T = 20ms. 在一个电力信号周期内每相上有两个过零点,被测节点检测到自身所在电力线上传输的电力信号处于过零点时,发送相别识别请求,故被测节点在每半个周期内便可以发送一次相别识别请求。 In a power signal cycle has two zero crossings on each phase, the measured node detects transmission power line itself is located in the power signal zero crossing, do not recognize the request sending phase, so the node under test in each half cycle will be You can send a request relative to other identification.

[0057] S102:获取接收到相别识别请求的接收时间以及帧数据报文的传输时间。 [0057] S102: Get received recognition reception time relative to other requests, and frame data packet transmission time.

[0058] 在本实施例中,相别识别请求的接收时间为:配电侧的接收节点接收到被测节点发送的相别识别请求时记录的时间。 [0058] In the present embodiment, the request is received relative to other time: the receiving node receives a distribution relative to other side of the recognition request sent by the node under test recording time. 例如,配电侧的接收节点时刻检测A相电力线上的电力信号,当检测到A相电力线上的电力信号处于过零点时,记录一次A相上过零点时间。 For example, the distribution side of the reception timing detection node A power line phase power signal, when it is detected to the A-phase power signals in the power line zero crossing, the recording time on the A-phase zero crossing time. 这里,可以根据客户需要,在配电侧的接收节点处设置一计时器,每当配电侧的接收节点检测到A相上的过零点时,计时器清零,从O开始重新计时。 Here, based on customer needs, the receiving node on the distribution side, setting a timer, whenever the receiving node detects the distribution side of the zero-crossing point on the A phase when the timer is cleared from O restarts the timer. 当接收到被测节点发送的相别识别请求时,计时器停止,保存当前计时器记录时间,即相别识别请求的接收时间。 When a request is received relative to other identification sent by the node under test, the timer is stopped, to save the current timer recording time, i.e., identifying the reception time relative to other requests.

[0059] 帧数据报文的传输时间为:被测节点发送相别识别请求到配电侧的接收节点接收到被测节点发送来相别识别请求的理论计算值。 Transmission time [0059] the frame data packets is: do not identify with the measured node sends a request to the receiving node receives the distribution side of the measured phase node sends to theoretical calculations do not recognize the request. 这里,帧数据报文中可以携带有相别识别请求长度、被测节点地址、主节点地址等相关信息,通过读取帧数据报文中的数据计算得到理论计算值。 Here, frame data packets can carry relative to other identification request length, the measured node address, the master node address and other relevant information obtained through the data to calculate the theoretical value read frame data packets.

[0060] S103:对接收时间和传输时间进行运算,依据运算结果,识别被测节点所在电力线的相别。 [0060] S103: the reception time and transmission time for computing, based on the calculation result, to identify where the node under test relative to other power line.

[0061] 在本实施例中,被测节点检测自身所在电力线上传输的电力信号处于过零点时发送相别识别请求,但由于系统本身存在的检测误差,无法达到在过零点时同步发送相别识别请求,过零点时刻和相别识别请求发送时刻存在一定偏差,因此,这里定义一固定延时时间AT1,被测节点检测到过零点时固定延时时间ATl后发送相别识别请求。 [0061] In the present embodiment, the node that detects a measured transmitted power where the power line zero crossing signal is transmitted relative to other identification request, but since the detection error of the system itself can not be reached at the zero crossing synchronous transmissions relative to other identification request, over Zero Hour and do not identify with the moment there is a certain deviation request, therefore, defined here after a fixed delay time AT1, measured node detects zero-crossing point fixed delay time relative to other ATl send the request. 在不同的设备环境中ATl值不一样,这里ATl的值可以根据配电台区的线路网络环境人为设定。 In a different context in ATl value is not the same, here ATl value can be set according to artificially line network environment with radio area.

[0062] 特别地,由于相别识别请求具有一定的长度,发送不同长度的相别识别请求存在不同的发送时间,发送相同长度的相别识别请求所需的发送时间是一样的,为了获得发送不同长度的相别识别请求所需的传输时间,相别识别请求所需的传输时间可以依据帧数据报文中携带的相别识别请求长度进行换算,通过换算获得相别识别请求的传输时间AT4,即帧数据报文的传输时间AT4。 [0062] In particular, since the phase do not have a certain length to identify the request, sending the identification of different lengths relative to other requests exist different transmission time, transmission time to send the same length relative to other recognition request is the same as required, in order to obtain the transmission transmission time required for the identification of different lengths relative to other requests, relative to other identification relative to other identification transmission time, requesting the basis of the frame data that can be carried in the request packet length conversion, obtained by converting the transmission time relative to other identification request AT4 that the transmission time frame data packets AT4.

[0063] 当然,在本实施例中,还可以预先设定传输时间AT4,该传输时间AT4用于保证不同长度的相别识别请求能够在该时间段内从被测节点完整发送至接收节点。 [0063] Of course, in the present embodiment, the transmission time can also be set in advance AT4, AT4 for securing the transmission time relative to other identification requests of different lengths can be transmitted in the time period from the complete test node to the receiving node.

[0064] 请结合图2和图3,图2示出了本申请提供的一种电力线相别识别方法的信号波形图,图3示出了本申请提供的一种电力线相别识别方法的信号传输过程时序图,进一步阐述说明电力线相别识别方法的实现原理。 [0064] Please conjunction with FIG. 2 and FIG. 3, FIG. 2 illustrates a power line of the present application provides a phase signal waveform diagrams respectively recognition method, FIG. 3 illustrates a power line signal provided herein relative to other identification method transmission timing diagrams illustrate further elaborate realization of the principle of power line with other identification methods.

[0065] 被测节点检测到A、B或C相处于过零点时,经固定延时时间A Tl后发送相别识别请求。 [0065] the measured node detects A, B or C phase is in zero crossing, after a fixed delay time A Tl transmission relative to other identification request. 因为电力信号采用三相传输方式,在被测节点同时依次检测A、B和C相上的过零点时,并结合图2可得,A、B和C相上相别识别请求的发送起始时间分别为:TA=AT1,TB=T/6+ ATI, TC=T/3+ A Tl的关系,进而可推出,在被测节点不同时依次检测A、B和C相上的过零点的情况下,A、B、C三相上的过零点具有n倍的T/6的关系,在本实施例中,T为电力信号中选用的低压电力线网络中的50Hz工频信号的周期,即A、B、C三相上的过零点具有n倍的3. 333ms的时间差。 Since three-phase power signal transmission, while sequentially detecting the measured node A, when the zero crossing point on the B and C phases, and can be obtained in conjunction with Figure 2, A, B and C do not identify with relative transmission start request time was: TA = AT1, TB = T / 6 + ATI, the relationship TC = T / 3 + A Tl, and thus can be introduced in the test node is not the same in order to detect A, B and C phase zero-crossing point on the relations case, the zero-A, B, C three phases have n times T / 6, in this embodiment, T is the power signal in selected low-voltage power line network 50Hz frequency of the periodic signal, namely Time off zero with n times the A, B, C three phases of 3. 333ms difference.

[0066] 配电侧的接收节点时刻检测任一相电力线上传输的电力信号,同时接收不同相上发送来的相别识别请求,记录不同相上被测节点发送的相别识别请求的接收时间。 [0066] The receiving node time detection of any one phase of the distribution side of the power line transmission of electric power signals received simultaneously transmitted on different phases relative to other identification request, records do not identify with the reception time measured on different phases node sends a request .

[0067] 在本实施例中,配电侧的接收节点时刻检测A相上的过零点,并接收A相被测节点、B相被测节点和C相被测节点发送来的相别识别请求。 [0067] In the present embodiment, the distribution side of the receiving node detects the zero crossing time on the A-phase and A-phase measured receiving node, B phase and C phase test node the node under test transmitted relative to other identification request . 在发送相别识别请求时,A、B、C相上的信号都固定了延时时间AT1,对于长度相同的相别识别请求其所需的发送时间AT4也是一样的。 When sending the phase do not recognize the request, A, B signals on the C phase, have a fixed time delay AT1, for the same length relative to other transmission time required to identify their request AT4 is the same. 配电侧的接收节点接收A、B、C相上发送来的相别识别请求后,利用计时器记录A、B、C相上相别识别请求的接收时间AT3A、AT3B和AT3C。 The receiving node receives the distribution side of A, B, C with the transmitted phase after another recognition request, using the timer records the reception time A, B, C-phase relative to other identification request AT3A, AT3B and AT3C. 从图3中可以得出,AT3A、AT3B和A T3C的时间值不一样,且存在如下关系: From Figure 3 can be drawn, AT3A, AT3B and A T3C time values are not the same, and there is the following relationship:

[0068] AT3A=( ATl+AT4)%(T/2); [0068] AT3A = (ATl + AT4)% (T / 2);

[0076] S201 :接收经由中继节点转发的被测节点发送的相别识别请求。 [0076] S201: phase do not recognize the request is received via the relay node forwards the measured node transmitted.

[0077] 由于电力线网络的复杂性和多样性,在某些台区中信号衰减比较大,有些台区中干扰比较大,很难保证点对点的直接通信成功率,故在本实施例中,信号传输采用中继方式,被测节点发送的信号通过中继节点转发,经过多级中继节点转发后接收,从而在不提高被测节点的信号发送功率的前提下,使得传输距离增加,有效地提高信号发送效率,进而可以实现信号的全覆盖。 [0077] Because of the complexity and diversity of the power line network, in some signal attenuation table area is relatively large, some of the interference is relatively large in the stage area, direct communication is difficult to ensure the success rate of point to point, so in this embodiment, the signal transmission using relay mode, the signal transmitted by the test node relay node forwarding, after the relay node forwards the received multi-level, so that the node under test without increase signal transmission power, so that the transmission distance increases, effectively improve the signal transmission efficiency, and can achieve full coverage of the signal.

[0083] 配电侧的接收节点接收相别识别请求后,根据ATI、AT2、AT3A、AT3B、AT3C、A T4和N计算得到被测节点的相别。 After the [0083] the distribution side of the receiving node receives relative to other identification request, do not get the test phase node according to ATI, AT2, AT3A, AT3B, AT3C, A T4 and N calculations. 其中,ATI、AT2、AT3A、AT3B、A T3C、A T4和N存在如下关系: Which, ATI, AT2, AT3A, AT3B, A T3C, A T4 and N has the following relationship:

[0084] AT3A=[ AT 1+ ( A T4+ A T2) *N+ A T4] % (T/2); [0084] AT3A = [AT 1+ (A T4 + A T2) * N + A T4]% (T / 2);

[0085] AT3B=[T/6+ATl+( AT4+AT2)*N+AT4]%(T/2); [0085] AT3B = [T / 6 + ATl + (AT4 + AT2) * N + AT4]% (T / 2);

[0086] A T3C= [T/3+ A Tl+ ( A T4+ A T2) *N+ A T4] % (T/2)。 [0086] A T3C = [T / 3 + A Tl + (A T4 + A T2) * N + A T4]% (T / 2).

[0088] 上述对AT的判定来识别被测节点所在电力线的相别可以为,在AT大于-T/12,不大于T/12时,识别被测节点所在电力线的相别为A相电力线;在AT大于T/12,不大于(T/12+T/6)时,识别被测节点所在电力线的相别为B相电力线;在AT大于(T/12+T/6),不大于(T/12+T/3)时,识别被测节点所在电力线的相别为C相电力线。 [0088] The determination of the AT to identify the node where the power line of the measured phase may not, in AT than -T / 12, not more than T / 12, it is recognized test node is located relative to other power line for the A-phase power line; When AT is greater than T / 12, not more than (T / 12 + T / 6), to identify the test node where the power line relative to other phase power line for B; the AT is greater than (T / 12 + T / 6), is not greater than ( T / 12 + T / 3), the identification of the test node is located relative to other power line phase power line as C.

[0089] 在本实施例中,信号传输采用中继方式,当台区规模大、距离远,被测节点发送的相别识别请求不能直接送达配电侧的接收节点时,被测节点发送的相别识别请求通过中继节点转发,不需要加大发送点的发送功率而实现相别识别请求的传输,并被配电侧的接收节点接收,使得传输距离达到全覆盖,有效地提高了被测节点的发送效率。 [0089] In this embodiment, the signal transmission using relay mode, when the station area is large in scale, distance, measured relative to other nodes in the identification request is not sent directly to the distribution side of the receiving node, the node sends test The recognition request relative to other relay nodes by forwarding, do not need to increase the transmission power of the transmission point is achieved relative to other identification of the transmission request, by the receiving node receives the distribution side, so that the transmission distance of up to full coverage, effectively improving the transmission efficiency measured node.

[0095] 在本实施例中,相别识别响应中携带的回复帧数据报文包括:被测节点地址、中继次数M、相别识别结果回复帧发送次数R和相别识别请求帧数据报文中的中继次数N,其中,因为相别识别响应在往返传输过程中经过的路径不一定一样,中继次数M记录了携带有回复帧数据报文的相别识别响应的中继转发次数,相别识别请求帧数据报文中的中继次数N记录了相别识别请求帧数据报文的中继转发次数,通过对比两者数值大小,便于用户明了信号的传输过程,相别识别结果回复帧发送次数R的大小表示了信号传输成功率的大小,通过查看相别识别结果回复帧发送次数R的值和被测节点处接收到的接收回复响应的次数,来判断是否需要布置中继节点。 [0095] In the present embodiment, the phase response do not identify the data carried in a reply message frame comprising: a test node address, the relay number M, relative to other response frame transmission number recognition result R and the identification request frame relative to other datagrams text relay number N, which, as with other identification response round trip path through the transmission process is not necessarily the same, the number of M record relay carrying reply frame data packets do not identify with the number of responses relayed , relative to other identification request frame relay data packets with the number of N records do not identify the request frame relay packet forwarding number, by comparing the value of both the size of the transfer process to facilitate the user to understand the signal, relative to other recognition results Reply frame transmission times the size of R indicates the size of the signal transmission rate of success, do not recognize the results by looking at the relative value and the measured frequency response at the node sends a frame number R received replies received in response, to determine whether to arrange a relay node.

[0106] 配电侧的接收节点接收A、B、C相上发送来的相别识别请求后,接收节点中的运算识别单元13利用计时器记录A、B、C相上相别识别请求的接收时间AT3A、A T3B和A T3C 的时间值分别为:A T3A= ( AT1+AT4) % (T/2),A T3B= (T/6+ ATI+A T4) % (T/2),AT3C=(T/3+ATl+AT4)%(T/2)。 [0106] The receiving node receives the distribution side of A, B, the C-phase relative to other identification transmitted the request, the receiving node identifying unit 13 uses a timer operation records A, B, C-phase relative to other identification request receiving time AT3A, time value A T3B and A T3C were: A T3A = (AT1 + AT4)% (T / 2), A T3B = (T / 6 + ATI + A T4)% (T / 2), AT3C = (T / 3 + ATl + AT4)% (T / 2). 依据公式AT=[ ( A Tl+A T4) - A T3x]%(T/2),对相别识别请求的接收时间和传输时间进行运算。 According to the formula AT = [(A Tl + A T4) - A T3x]% (T / 2), relative to other identification of the request reception time and transmission time for calculation. 其中A Tl+A T4为被测节点发送相别识别请求到配电侧的接收节点接收到被测节点发送来相别识别请求的理论计算值,△ T3x为相别识别请求的接收时间,T为电力信号中选用的低压电力线网络中的50Hz工频信号的周期,x表示电力线的相别,通过对AT的判定来识别被测节点所在电力线的相别。 Wherein A Tl + A T4 is measured relative to other node sends a request to the receiving node to identify the distribution side of the receiving node sends to the measured phase to the theoretical value of other identification request, △ T3x other for phase identification request reception time, T for power signals selected low-voltage power line network 50Hz frequency signal cycle, x represents another phase power line, judging by AT measured relative to other nodes to identify where power lines.

[0107] 识别方式可以为,在AT大于-T/12,不大于T/12时,识别被测节点所在电力线的相别为A相电力线;在AT大于T/12,不大于(T/12+T/6)时,识别被测节点所在电力线的相别为B相电力线;在AT大于(T/12+T/6),不大于(T/12+T/3)时,识别被测节点所在电力线的相别为C相电力线。 [0107] identify ways that, in the AT greater than -T / 12, not more than T / 12, the identification test node is located relative to other power line for the A-phase power line; at AT greater than T / 12, not more than (T / 12 + T / 6), the identification of the test node is located relative to other power line phase power line for B; the AT is greater than (T / 12 + T / 6), is not greater than (T / 12 + T / 3), the recognition test phase node where the power lines do not phase power line C.

[0108] 再一个实施例[0109] 由于电力线网络的复杂性和多样性,在某些台区中信号衰减比较大,有些台区中干扰比较大,很难保证点对点的直接通信成功率,故在本实施例中,信号传输采用中继方式,被测节点发送的信号通过中继节点转发,经过多级中继节点转发后接收,此时接收单元11接收到的相别识别请求可以为被测节点间隔固定延时时间ATl后,再经由中继节点转发的相别识别请求,其中中继节点联接在被测节点和接收节点之间。 [0108] Yet another embodiment of the [0109] Because of the complexity and diversity of the power line network, in some station area is relatively large signal attenuation, interference in some stage area is relatively large, it is difficult to ensure that the success rate of direct communication point, so In the present embodiment, signal transmission using relay mode, the signal measured by the relay node sends the forwarding nodes, relay nodes after forwarding the received multi-level, then the receiving unit 11 receives the request relative to other identification may be sensor node after a fixed delay time interval ATl, and then forwarded via the relay node relative to other identification request, in which the relay node is coupled between the measured and receiving nodes. 特别地,相别识别请求是经由中继节点间隔固定延时时间AT2后转发的相别识别请求。 In particular, do not identify with the request not to recognize the request is a fixed interval relative time delay after AT2 forwarded via the relay node.

[0110] 在本实施例中,相别识别请求经过多级中继节点转发,由于中继节点在转发相别识别请求时会发生延时,故在中继节点接收到相别识别请求后,间隔固定延时时间AT2,再转发相别识别请求。 [0110] In the present embodiment, the recognition request relative to other relay node forwards through the multi-stage, occurs due to the delay in the relay node to forward the request relative to other identification, so the relay node after receiving the request relative to other identification, fixed delay time interval AT2, and then forwards the request relative to other identification.
