[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] In view of the low efficiency of current point-to-point testing, the present invention provides a method for realizing efficient point-to-point joint debugging of distribution automation terminals based on differentiated comparison of electrical quantity characteristics. The efficient and fast point-to-point joint debugging test of distribution automation terminals is completed by a differentiated quantity increase method, ensuring that batch distribution automation terminals can be put into operation quickly, and realizing a single quantity increase fault simulation test to realize unified point-to-point joint debugging of remote adjustment, telemetry, telesignaling, and remote control.

[0022] Combine the following Figures 1 to 3The point-to-point joint adjustment method and device of distribution terminals based on the differentiation of electrical quantity characteristics of the present invention are described. Figure 1 This is one of the flow charts of the point-to-point joint debugging method of the power distribution terminal based on the differentiation of electrical quantity characteristics according to an embodiment of the present invention. Figure 1 As shown, the present invention provides a point-to-point joint adjustment method for distribution terminals based on the differentiation of electrical quantity characteristics, comprising:

[0023] S1. Send a point-to-point joint debugging work order to the joint debugging device, so that the joint debugging device can generate a corresponding debugging plan and feed it back to the distribution automation master station.

[0024] Before S1, build a test environment to ensure normal communication and correct physical wiring between the distribution automation master station, distribution automation terminal, and joint debugging device.

[0025] The distribution automation master station issues a point-to-point joint debugging work order to the joint debugging device. The joint debugging device generates a related debugging plan based on the point-to-point joint debugging work order and feeds the debugging plan back to the master station system for the master station system to judge the results during the joint debugging process. An example of a point-to-point joint debugging work order is shown in Table 1:

[0026] Table 1

[0027] Serial number telemetry Remote Control remote message remote control 1 Phase A current Fixed value operation Overcurrent protection action Remote control switch 2 Phase B current Switch closed Remote control switch 3 Phase C current Switch position 4 Zero sequence phase current 5 Phase A voltage 6 Phase B voltage 7 Phase C voltage 8 Zero sequence voltage 9 P Active power 10 QReactive power 11 S Apparent power 12 COS Power Factor 13 F Frequency

[0028] S2. After receiving the joint debugging request sent by the joint debugging device, a remote debugging test is performed on the distribution terminal, wherein the remote debugging test includes a fixed value reading and writing verification of the distribution terminal, wherein the writing fixed value of the remote debugging test is set according to the debugging scheme.

[0029] The point-to-point joint debugging process is completed by three steps of testing. The first step is the remote adjustment of S2, that is, to realize the reading and writing verification of the fixed value of the distribution automation terminal. Specifically, the distribution automation terminal can be read and modified through the distribution automation master station, and the fixed value can be read again to verify whether the remote adjustment is completed.

[0030] S3. After the remote adjustment test is qualified, the telemetry and telesignaling point test start information is sent to the joint adjustment device, so that the joint adjustment device can perform differentiated additions according to the debugging plan, and perform differentiated comparison with the debugging plan based on the response information sent up by the distribution terminal after the differentiated addition, so as to realize point verification of telemetry of different phases and telesignaling of different positions.

[0031] The second step is to achieve simultaneous telemetry and telesignaling, and increase the amount of the distribution automation terminal through the joint adjustment device. Among them, the increase is differentiated, which ensures the action outlet of the terminal protection function, different telemetry amplitudes of different phases, and responsive changes in the switch position. Specifically, differentiated values ​​are applied to the voltage and current channels of different phases, and at the same time, it is ensured that the applied current can drive the overcurrent protection action of the distribution automation terminal, and the relevant switch position and protection action telesignaling can be sent to the distribution automation master station system in time. The master station system determines the telemetry value and telesignaling position sent by the terminal to complete the telemetry and telesignaling.

[0032] S4. After the telemetering and telesignaling point verification is qualified, the remote control switch closing and opening operation instructions are sent to the distribution terminal, and the remote control point is judged whether it is qualified according to the changes in the switch position and telesignaling position.

[0033] The third step is to complete the remote control point-to-point. After the protection action, the simulated switch is in the open position. The distribution automation master station system sends remote control switch closing and opening operation instructions to the distribution automation terminal in sequence. The distribution automation master station system determines whether the remote control point-to-point is qualified based on the change of the switch position telesignal position, and finally completes the remote control point-to-point.

[0034] In summary, the above method is that the joint debugging device simulates the fault through the voltage, current signal value and the simulated switch position, the distribution automation terminal performs logical judgment on the fault simulation, and sends the relevant electrical quantity characteristic signal to the distribution automation master station. The distribution automation master station performs differentiated comparison based on the test information fed back by the joint debugging device, and differentiates the correctness of the relevant telemetry, telesignaling, and teleadjustment point information according to the different types and different phase values. At the same time, after the fault simulation is completed, the distribution automation master station performs remote control reset and switch position restoration remote control operations on the distribution automation terminal, and judges the correctness of the remote control point information through the position telesignaling of the corresponding simulated switch.

[0035] The point-to-point joint debugging method of distribution terminals based on differentiated electrical quantity characteristics of the present invention first generates a targeted debugging plan through information interaction between the master station and the distribution network terminal and the debugging device, which provides data support for subsequent remote adjustment, telemetry, telesignaling and remote control joint debugging. Secondly, the reliability of the set value is ensured through the first step of interactive remote adjustment test, which provides accuracy guarantee for subsequent telemetry, telesignaling and remote control joint debugging. Combined with the differentiated quantity addition method in the second step of telemetry and telesignaling, the point-to-point joint debugging test of the distribution automation terminal can be completed efficiently, quickly and accurately, and ultimately the efficiency of the entire adjustment process is significantly improved, which is conducive to the rapid batch commissioning of the distribution automation terminal, improves the online rate of the distribution automation system terminal and the coverage rate of the distribution automation system, and then ensures the reliability of the power supply of the distribution network.

[0036] In one embodiment, before sending the point-to-point joint debugging work order to the joint debugging device, the method further includes: generating a corresponding point-to-point joint debugging work order based on the point table file of the distribution automation terminal and the distribution automation master station. Specifically, the relevant debugging task list and debugging plan can be generated based on the point table file of the distribution automation terminal and the distribution automation master station.

[0037] In one embodiment, after sending the point-to-point joint debugging job form to the joint debugging device, it also includes: calibrating the received debugging plan according to the point-to-point joint debugging job form, and after the calibration result is qualified, sending the calibration result to the joint debugging device, so that the joint debugging device can initiate a joint debugging request after receiving the qualified result.

[0038] A qualified judgment step can be added to start the subsequent related point-to-point joint debugging test on the premise that the debugging work order and debugging plan are qualified. If the joint debugging device receives a qualified calibration result, it means that the debugging plan is correct and the subsequent joint debugging can be carried out smoothly. If a qualified calibration result is not received, the joint debugging request will not be initiated and the entire debugging process will not be carried out temporarily, thereby ensuring the accuracy and reliability of the joint debugging result.

[0039] In one embodiment, after calibrating the received debugging scheme according to the point joint debugging job order, it also includes: if the calibration result is unqualified, repeating the joint debugging job order according to the locally stored point table file, eliminating the defects, and sending the joint debugging job order after the defects are eliminated to the joint debugging device, and calibrating the received debugging scheme according to the new joint debugging job order until the calibration result is qualified.

[0040] Figure 2 This is a second flow chart of a method for point-to-point joint adjustment of power distribution terminals based on differentiation of electrical quantity characteristics according to an embodiment of the present invention. Figure 2 As shown, if the calibration and debugging worksheet and the debugging plan are unqualified, the checkpoint table file is checked and the defects are eliminated, and then the joint debugging device automatically generates a debugging plan according to the new debugging worksheet and feeds it back to the main station, and repeats this process until the calibration and debugging worksheet and the debugging plan are qualified, and then the subsequent joint debugging steps are performed. Based on the method of the embodiment of the present invention, it is possible to automatically eliminate the defects of the unqualified debugging plan, thereby ensuring the accuracy and efficiency of the joint debugging.

[0041] In one embodiment, after judging whether the remote control point is qualified according to the change of the switch position and the remote signal position, the method further includes: summarizing the related remote adjustment, remote measurement, remote signal and remote control point joint debugging test results, generating a test report for archiving. Figure 3 As shown, after the remote control point-to-point test is qualified, the distribution automation master station system will summarize the relevant remote adjustment, telemetry, telesignaling and remote control point-to-point joint debugging test results, and generate a test report for archiving, which can be specifically archived on the master station side and the joint debugging device side respectively.

[0042] In one embodiment, the differentiated addition includes outputting voltages with different amplitudes and phases, and current signals with different amplitudes and phases to different channels.

[0043] Taking the process of joint adjustment based on overcurrent protection as an example, the primary transformation ratio of the three-phase voltage and zero-sequence voltage of the distribution automation terminal is 10kV:0.1kV, the current transformation ratio is 600:5, the zero-sequence voltage transformation ratio is 100:1, and the zero-sequence current transformation ratio is 100:1. In the first step of remote adjustment and joint adjustment, the overcurrent three-stage secondary protection setting is set to 6A. In the second step of telemetry and telesignaling, the joint adjustment device sets different channels to output voltage and current signals with different amplitudes and phases, such as three-phase voltage outputs of 40V, 50V, and 60V, three-phase current outputs of 3A, 5A, and 7A, voltage and current positive sequence output, phase fixed deviation of 30°, zero-sequence voltage and zero-sequence current outputs are set to 100V and 1A, respectively, the initial value of the analog switch is closed, and after the protection action is adjusted to divided through the protection action outlet, it is finally realized that the overcurrent three-stage protection can be reliably operated after the action and the relevant telesignaling message is sent to the distribution automation master station system. At the same time, the three-phase voltage, three-phase current, zero-sequence voltage and current, active power, reactive power, power factor, frequency and other telemetry are sent to the main station system with different amplitudes, so that the telemetering and telemetry can be coordinated at the same time. The specific values ​​are shown in Table 2:
