In this embodiment, it is first required to explain that the power consumption of the power distribution network is a link facing the user side in the smart power grid, and is an important platform supporting the response management of the demand side to bear a large amount of distributed energy sources such as distributed power generation and electric vehicles, and the automation terminal is used as an important component of the power distribution network, and is applied to the power distribution network feeder, and can monitor the electrical quantity information (telemetry) on the feeder in real time, send switch state data (telemetry) in real time, execute the command issued by the power distribution main station, regulate and control (remote control) the power distribution equipment, and realize functions such as fault location, fault isolation, and rapid recovery of power supply in non-fault areas. Along with the structure of the power distribution network is more and more complex, the functions are more and more complete, so that power supply, electricity consumption and the like are more intelligent, and meanwhile, great difficulty is brought to power grid inspection and maintenance. To cope with this problem, techniques such as power distribution network fault detection, self-healing research, safety protection and the like have been developed. In the self-healing test mode of the power distribution network, the common self-healing test modes mainly include a centralized control mode and a master station on-site cooperative mode, synchronous tests are required to be carried out on at least three or more automatic terminals when the self-healing function test is carried out on the master station on-site cooperative mode, obviously, the information interaction performance among the automatic terminals is a key for influencing the self-healing capacity of the power distribution network, and therefore in the embodiment, the self-healing test mode of the power distribution network mainly aims at the master station on-site cooperative mode, the self-healing function after the data interaction of the automatic terminals is failed is rapidly evaluated, and the self-healing capacity of the power distribution network is further tested.
Specifically, in step S10, a test script and a control script transmitted by the master terminal 01 are first received, where the test script refers to a series of instructions of a specific test, which may be executed by an automated test tool.

Further, in step S20, according to the received test script, a normal test sequence, a fault test sequence or an isolation test sequence is input to the automated terminal 06 to be tested, and an actual switching signal of the automated terminal 06 to be tested is obtained; it can be understood that different time sequence tests are set, the corresponding actual switching signal results can be compared, and the fault state is simulated according to the test results for executing the subsequent steps.
Next, in step S30, the communication unit of the to-be-tested automation terminal 06 is controlled mainly according to the simulated fault state, so as to obtain an actual feedback signal of the to-be-tested automation terminal 06; the specific method comprises the following steps: acquiring a feedback signal to be received of the automatic terminal 06 to be detected, processing the feedback signal to be received according to a control script, and then transmitting the processed feedback signal to be received to the automatic terminal 06 to be detected; and acquiring an actual feedback signal sent by the automatic terminal 06 to be tested at the moment;
finally, in step S40, the actual switching signal and the actual feedback signal are sent to the master control terminal 01, and the master control terminal 01 performs a comparison analysis according to the two signals to obtain a self-healing function test result of the automated terminal 06 to be tested.

In an embodiment, the method further comprises outputting a corresponding normal test sequence, fault test sequence or isolation test sequence to the automated terminal 06 to be tested according to the test script and the feedback signal to be received.
The test script comprises a normal test time sequence of a test initial state which corresponds to the automatic terminal 06 to be tested and operates in a normal state, wherein the initial state is uniformly set according to each automatic terminal; and when the target fault terminal fails, the automatic terminal 06 to be tested fails, and the fault test time sequence corresponding to the initial fault state of the automatic terminal 06 to be tested. The test script also comprises a control instruction for the fault test time sequence triggered according to the feedback signal to be received.
Further, the fault test time sequence includes the initial fault state of the to-be-tested automation terminal 06 when the target fault terminal fails, and the fault test time sequence can only change the to-be-tested automation terminal 06 through the feedback signal to be received, namely, the simulation state of the to-be-tested automation terminal when the corresponding action or feedback is taken by the neighborhood automation terminal is further simulated through the feedback information of the neighborhood automation terminal.
Finally, the normal test time sequence can be a voltage signal and/or a current signal of the automatic terminal 06 to be tested before the target fault terminal fails, and the voltage and current change of the automatic terminal 06 to be tested before the fault occurs can be simulated through the normal test time sequence; the fault test time sequence can be a voltage signal and/or a current signal when the automatic terminal 06 to be tested fails at the target fault terminal, and the voltage and current change of the automatic terminal 06 to be tested when the fault occurs can be simulated through the fault test time sequence; the isolation test time sequence can be a voltage signal and/or a current signal when the automated terminal 06 to be tested performs fault isolation on the target fault terminal, and the voltage and current change of the automated terminal 06 to be tested during fault isolation can be simulated through the isolation test time sequence.
According to the test script provided by the embodiment of the invention, the normal test time sequence, the fault test time sequence or the isolation test time sequence are set, so that the fault state can be effectively simulated aiming at the test result, the test script is used for subsequent comparative analysis, the cost is low, and the practicability is strong.
In a certain embodiment, in the master station in-situ cooperation type network mode, information interaction and feedback performance between the automation terminals are tested, particularly feedback information received by the automation terminals is monitored, when the automation terminal 06 to be tested is to receive the feedback information sent by the neighborhood automation terminal, the feedback information is processed according to a test state first, so that faults of the automation terminal 06 to be tested in the information interaction process are simulated, and self-healing function performance of the automation terminal 06 to be tested in the information interaction process is tested.
In a certain embodiment, each automated terminal 06 to be tested corresponds to each node in the power line topological graph one by one, and is in communication connection with a neighborhood automated terminal corresponding to a neighborhood node in the power line topological graph; the feedback signal to be received comprises a signal sent by the neighborhood automation terminal to the automation terminal to be detected 06. It can be understood that under the condition that the automated terminal 06 to be tested corresponds to each node in the power line topological graph one by one, a more comprehensive feedback signal can be obtained, and further the accuracy of a subsequent test result is ensured.
In a certain embodiment, the method further comprises: the communication unit of the to-be-detected automation terminal 06 is monitored, when the communication unit is detected to receive the to-be-received feedback signal sent by the neighborhood automation terminal, the control unit 05 processes the to-be-received feedback signal according to the communication control script, the processed to-be-received feedback signal is returned to the to-be-detected automation terminal 06, and the response of the to-be-detected automation terminal 06 according to the processed to-be-received feedback signal is recorded, wherein the response comprises the actual switching signal of the to-be-detected automation terminal 06 and the actual feedback signal sent by the same.
In the master station local cooperative distribution network mode, the automatic terminal acquires global distribution network information by means of feedback information of the neighborhood automatic terminals. Therefore, if the communication of the neighborhood automation terminal is blocked, whether the automation terminal 06 to be tested can still complete the self-healing function of the distribution network becomes a key for evaluating the reliability of the automation terminal. Therefore, aiming at the situation, the feedback information sent by the neighborhood automatic terminal is intercepted, then the feedback information sent by the neighborhood automatic terminal is compared with the target terminal ID marked in the communication control script and with communication faults, and when the neighborhood automatic terminal is the target communication fault automatic terminal simulating the faults, the feedback information is compared, so that the automatic terminal 06 to be tested cannot receive the feedback information; and meanwhile, according to the actual situation of the feedback information, updating the corresponding current/voltage signal of the automatic terminal 06 to be tested. And simultaneously, recording the response of the automatic terminal 06 to be tested, sending the obtained response to the master control terminal 01, and judging the self-healing function test result of the automatic terminal 06 to be tested by the master control terminal 01.
The communication control script records an automatic terminal with communication faults in the test environment, and when the sending end of the received feedback information is matched with the automatic terminal with the communication faults, the feedback information is shielded. So that the automated terminal 06 to be tested cannot normally receive the feedback information, so as to simulate the situation that the neighborhood automated terminal has communication faults. It is emphasized that the simulation method has the advantages of low cost and strong stability.
In a certain embodiment, the processing of the feedback information to be received further includes noise adding processing on the feedback information to be received, so as to effectively simulate the processing situation of the automated terminal 06 to be tested when the quality of the received feedback information is affected. The feedback information comprises a control instruction or information feedback of the state of the user.

By setting the normal test time sequence, the fault test time sequence or the isolation test time sequence, the fault state can be effectively simulated aiming at the test result, and the fault state is used for subsequent comparison analysis, so that the cost is low and the feasibility is strong.
In an embodiment, the master control terminal 01 generates a test script corresponding to each automation terminal according to the power line topological graph, the target fault terminal and the target fault type, wherein the test script comprises a current signal and/or a voltage signal of the automation terminal 06 to be tested in a normal state; when the target fault terminal fails, the current signal and/or the voltage signal of the automatic terminal 06 to be tested; the time of each automation terminal is uniform, and when the test time is entered, the state of each automation terminal is changed from a normal state to a fault state; when the automatic terminal monitors a fault, the automatic terminal feeds back a corresponding control instruction or information feedback to the neighborhood automatic terminal according to the fault state information, and receives feedback information sent by the neighborhood automatic terminal; the automation terminal 06 to be tested further executes corresponding operation (such as actual switch signal) or further feeds back corresponding information (actual feedback information) according to the received feedback information; the test unit 04 and the control unit 05 respectively acquire an actual switching signal and actual feedback information of the automatic terminal 06 to be tested and transmit the actual switching signal and the actual feedback information to the master control terminal 01, and the master control terminal 01 is matched with a set target switching signal and target feedback information according to the acquired actual switching signal and the actual feedback information so as to evaluate the self-healing function of the distribution network of the automatic terminal 06 to be tested.
Meanwhile, aiming at the situation of further testing when the communication fault occurs in the neighborhood automatic terminal, the master control terminal 01 generates a corresponding communication control script according to the automatic terminal with the communication fault, wherein the communication control script comprises ID information of the communication fault or the type of the communication fault. The control unit 05 intercepts feedback information to be received of the to-be-detected automation terminal 06, processes the intercepted feedback information to be received (for example, increases noise or shields feedback information sent by a specified automation terminal) according to a communication control script, and transmits the processed feedback information to be received to the to-be-detected automation terminal 06, so that the to-be-detected automation terminal 06 simulates a situation under a communication fault state (for example, the feedback information is missing, and the automation terminal is interfered). Meanwhile, the test unit 04 and the control unit 05 further acquire actual switching signals and actual feedback information of the automatic terminal 06 to be tested so as to test the self-healing function of the distribution network of the automatic terminal 06 to be tested under the condition of communication faults, and the self-healing test effect of the distribution network in the local collaborative distribution network mode of the master station is improved.
Meanwhile, the test unit 04 can trigger the change of the fault time sequence (current/voltage information) of the automated terminal 06 to be tested according to the feedback information to be received sent by the adjacent automated terminal so as to simulate the actual situation under the test state. The automation terminal 06 to be tested executes corresponding self-healing function (feeds back corresponding feedback information to the neighborhood automation terminal or executes corresponding switch control) according to the current fault state (current/voltage information) and the received feedback information (feedback information processed by the control unit 05) of the neighborhood automation terminal.
