In this embodiment, it should be first mentioned that power consumption of a power distribution network is a link facing a user side in an intelligent power grid, and is an important platform for supporting a demand side to respond, manage and bear a large amount of distributed energy such as distributed power generation and electric vehicles, and an automation terminal is an important component of the power distribution network, and is applied to a power distribution network feeder line, and can monitor electrical quantity information (telemetry) on the feeder line in real time, upload switch state data (telemetry) in real time, execute a command issued by a power distribution main station, adjust and control (telemetry) power distribution equipment, and realize functions such as fault location, fault isolation, and rapid power restoration in a non-fault area. Along with the distribution network structure is more and more complicated, and the function is also more and more complete for power supply power consumption etc. are more intelligent, but also patrol and examine and maintain for the electric wire netting simultaneously and bring very big difficulty. In order to solve the problem, technologies such as power distribution network fault detection, self-healing research, safety protection and the like are developed. Wherein, in the distribution network self-healing test mode, common mainly divide into centralized control type, main website cooperation type two types on the spot, in regard to main website cooperation type on the spot, need carry out synchronous test to at least three and above automation terminal when carrying out the self-healing function test, obviously, information interaction performance between the automation terminal is the key that influences the distribution network self-healing ability, consequently, mainly to the distribution network self-healing test under the main website cooperation type mode in this embodiment, provide a method and assess the self-healing function after the automation terminal data interaction breaks down fast, and then inspect the distribution network self-healing ability.
Specifically, in step S10, a test script and a control script transmitted by the central control terminal 01 are received, wherein the test script refers to a series of instructions of a specific test, and the instructions can be executed by the automated testing tool.

Further, in step S20, according to the received test script, a normal test timing sequence, a fault test timing sequence, or an isolation test timing sequence is input to the automation terminal 06 to be tested, and an actual switching signal of the automation terminal 06 to be tested is obtained; it can be understood that different timing tests are set, corresponding actual switching signal results can be compared, and a fault state can be simulated according to the test results for execution of subsequent steps.
Then, in step S30, the communication unit of the automation terminal 06 to be tested is controlled mainly according to the simulated fault state, so as to obtain an actual feedback signal of the automation terminal 06 to be tested; the specific method comprises the following steps: acquiring a feedback signal to be received of the automation terminal 06 to be detected, processing the feedback signal to be received according to the control script, and transmitting the processed feedback signal to be received to the automation terminal 06 to be detected; and acquiring an actual feedback signal sent by the automation terminal 06 to be tested at the moment;

In the embodiment of the invention, the master control terminal 01 automatically generates the test scripts of the to-be-tested automation terminals 06 according to the power line topology, the target fault terminal and the target fault type, simulates the fault working state of the to-be-tested automation terminals 06, and simultaneously acquires the actual switching signals of the to-be-tested automation terminals 06 so as to quickly and effectively detect the self-healing function of the to-be-tested automation terminals 06, so that the safety and the stability are high.
In one embodiment, the method further includes outputting a corresponding normal test timing sequence, a corresponding fault test timing sequence, or a corresponding isolation test timing sequence to the automation terminal 06 to be tested according to the test script and the feedback signal to be received.
The test script comprises a test initial state normal test time sequence which corresponds to the automation terminal 06 to be tested and runs in a normal state, wherein the initial state is uniformly set according to each automation terminal; and a fault test time sequence corresponding to the initial fault state of the automation terminal 06 to be tested when the target fault terminal has a fault at the automation 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 timing sequence includes an initial fault state of the automation terminal 06 to be tested when the target fault terminal is faulty, and the fault test timing sequence can be changed only by the feedback signal to be received, that is, the simulation state of the fault terminal to be tested when the neighborhood automation terminal takes a corresponding action or feedback is further simulated by 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 of the automatic terminal 06 to be tested when a target fault terminal has a fault, 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 of the to-be-tested automation terminal 06 when the target fault terminal is subjected to fault isolation, and the voltage and current change of the to-be-tested automation terminal 06 when the fault is isolated can be simulated through the isolation test time sequence.
The test script provided by the embodiment of the invention can effectively simulate a fault state aiming at a test result by setting a normal test time sequence, a fault test time sequence or an isolation test time sequence, is used for subsequent comparison and analysis, and has low cost and strong implementability.
In one embodiment, in a distribution network mode of a master station local coordination type, information interaction and feedback performance between automation terminals are tested, especially feedback information received by the automation terminals is monitored, when the automation terminal 06 to be tested receives the feedback information sent by a neighborhood automation terminal, the feedback information is processed according to a test state to simulate a fault of the automation terminal 06 to be tested in an information interaction process, and therefore self-healing functional performance of the automation terminal 06 to be tested when the fault occurs in the information interaction process is tested.
In one embodiment, each of the to-be-tested automation terminals 06 corresponds to each node in the power line topological graph one to one, and is in communication connection with a neighborhood automation terminal corresponding to a neighborhood node in the power line topological graph; the feedback signal to be received includes a signal sent from the neighborhood automation terminal to the automation terminal 06 to be detected. It can be understood that under the condition that the automation terminal 06 to be tested corresponds to each node in the power line topological graph one to one, a more comprehensive feedback signal can be obtained, and the accuracy of a subsequent test result is further ensured.
In a certain embodiment, the method further comprises: monitoring a communication unit of the automation terminal 06 to be detected, when detecting that the communication unit receives a feedback signal to be received sent by a neighborhood automation terminal, processing the feedback signal to be received by the communication control unit 05 according to a communication control script, returning the processed feedback signal to be received to the automation terminal 06 to be detected, and recording a response made by the automation terminal 06 to be detected according to the processed feedback signal to be received, wherein the response comprises an actual switching signal of the automation terminal 06 to be detected and an actual feedback signal sent by the actual switching signal.
In the local cooperative distribution network mode of the main station, the automatic terminal acquires the global information of the distribution network by depending on the feedback information of the neighborhood automatic terminal. Therefore, whether the automatic terminal 06 to be tested can still complete the distribution network self-healing function becomes a key for evaluating the reliability of the automatic terminal under the condition that the communication of the neighborhood automatic terminal is blocked. Therefore, for the above situation, feedback information sent by the neighborhood automation terminal is intercepted, then the feedback information sent by the neighborhood automation terminal is compared with the target terminal ID with the communication fault marked in the communication control script, and when the neighborhood automation terminal is the target communication fault automation terminal with the simulated fault, the feedback information is compared, so that the automation terminal to be tested 06 cannot receive the feedback information; and meanwhile, updating the corresponding current/voltage signal of the automatic terminal 06 to be tested according to the actual condition of the feedback information. And meanwhile, recording the response of the automation 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 automation terminal 06 to be tested by the master control terminal 01.
The communication control script records an automatic terminal with a communication fault in a test environment, and when a sending end of received feedback information is matched with the automatic terminal with the communication fault, the feedback information is shielded. So that the automation terminal 06 to be tested cannot normally receive the feedback information, and the condition that the communication fault occurs in the neighborhood automation terminal is simulated. It is emphasized that the simulation method has the advantages of low cost and strong stability.
In one embodiment, the processing of the feedback information to be received further includes performing noise processing on the feedback information to be received, so as to effectively simulate the processing condition of the to-be-tested automation terminal 06 when the quality of the received feedback information is affected. The feedback information comprises a control instruction or information feedback of the self state. Through the noise-added fault simulation of the embodiment, the fault state of the communication of the automatic terminal can be simulated more accurately, and the accuracy of the self-healing function test is improved.

The communication 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 according to the communication control script (for example, adds noise or shields feedback information sent by a specific automation terminal), 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 the situation under the communication fault state (for example, the feedback information is missing, and the automation terminal is interfered). Meanwhile, the test unit 04 and the communication 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 distribution network self-healing function of the automatic terminal 06 to be tested under the condition of communication faults, and the distribution network self-healing test effect in a distribution network mode aiming at the on-site cooperation of the master station is improved.
Meanwhile, the test unit 04 can also trigger the change of the fault timing sequence (current/voltage information) of the automation terminal 06 to be tested according to the feedback information to be received sent by the neighborhood automation terminals, so as to simulate the actual situation under the test state. The automation terminal 06 to be tested executes a corresponding self-healing function (feeds back corresponding feedback information to the neighborhood automation terminals or executes corresponding on-off control) according to the current fault state (current/voltage information) and the received feedback information of the neighborhood automation terminals (feedback information processed by the communication control unit 05).
