The one-key sequential control technology is a switching operation mode which is raised in a transformer substation in recent years, and has the functions of realizing project software prefabrication, operation task modular construction, automatic equipment state discrimination, error-preventing interlocking intelligent check, one-key starting operation steps, automatic sequential execution operation processes and the like, for example, the prior patent application document of the invention with the publication number of CN110568284A, namely an intelligent transformer substation one-key sequential control automatic test verification method, device and system, comprises the steps of receiving a sequential control request sent by a monitoring host; driving the simulated intelligent device control service to respond to the sequential control request according to the preconfigured intelligent device sequential control logic; sequential control logic for collecting response data obtained by the monitoring host; and comparing the sequence control logic of the response data with the sequence control logic of the configured intelligent equipment to obtain a test result. The prior patent application document of the invention with publication number of CN116775224A, namely a one-key sequential control test system and a test method, comprises the following steps: the system comprises a sequential control host and an integrated device, wherein the integrated device comprises a one-key sequential control test module, a virtual machine main pipe platform and at least one equipment virtual machine; the sequential control host sends a key sequential control command; the one-key sequential control testing module receives a one-key sequential control command, analyzes the one-key sequential control command to obtain an analyzed sequential control command and remote control point information, and sends the analyzed sequential control command and remote control point information to the virtual machine main pipe platform; the virtual machine main pipe platform receives the analyzed sequential control command and the remote control point information, and sends the analyzed sequential control command to the equipment virtual machine according to the remote control point information; and testing the one-key sequential control command sent by the sequential control host through the configured equipment virtual machine to obtain a judging result, and sending the judging result to the one-key sequential control testing module so that the one-key sequential control testing module analyzes the judging result to obtain a final testing result of the sequential control host. The method of the invention is that a station monitoring system comprises a monitoring host, an intelligent five-prevention machine and a measurement and control device, and comprises the following contents: and (1) checking without power failure: the monitoring host monitors the state of the total station equipment, acquires the running state data of the primary equipment and the secondary equipment of the current time section, and stores section data, namely analog state data, in a local database; meanwhile, the monitoring host realizes bidirectional switching of a monitoring real-time state image and an analog state image, the real-time state image reads real-time running state data of the primary equipment and the secondary equipment, and the analog state image reads analog state data stored in a local database; the monitoring host realizes the isolation of the data and the pictures in the simulation state and the data and the pictures in the running state, and all simulation checking operations are carried out in the simulation database without changing the real-time database; and (2) visual checking: the monitoring host acquires the analog state data of the current time section, and switches the monitoring real-time picture of the monitoring host to the analog state picture, and the analog state picture visually displays the task content of the operation ticket and the primitive state of the corresponding analog state data of the monitoring picture.
In the prior art, the acceptance of the one-key sequential control function depends on actual primary and secondary equipment in a transformer substation due to the lack of necessary testing tools, so that the equipment acceptance depends on a power failure plan.
Taking a 500kV transformer substation as an example, because the transformer substation is in a core position in a system, power failure is partial power failure, and according to the state maintenance test rules of power transmission and transformation equipment, for a power failure test, the longest test period is 1.5 times of a reference period, and then 1 is added. The reference period of the power transmission and transformation equipment is 3 years, the routine test period of power failure, which is endangered to the abnormal defect of operation and is evaluated as normal for the last time, can be prolonged, but the maximum test period is not more than 5.5 years. Thus, all equipment of the transformer substation has a power failure for 5-6 years basically, the power failure is specially limited by the power failure plan balance and the power failure window of the power system for one-key sequential control acceptance inspection, and the acceptance inspection progress is highly lagged compared with the one-key sequential control improvement progress, so that the application of one-key sequential control technology is restricted.
In conclusion, the verification operation in the prior art relies on the power failure to simulate the operation condition in the power station, and the verification efficiency of the one-key sequential control system is low, so that the technical problem that the one-key sequential control technology is restricted in popularization is caused.
