Problems solved by technology

If the regional standby automatic switching system is not tested before it is put into operation, it will bring huge hidden dangers to the power grid. In addition, if there is a malfunction without testing, it may cause large-scale power outages; if the series supply line or transformer is repaired may also result in the risk of personal accidents

Embodiment Construction

[0023] The present invention will be further elaborated below in conjunction with specific embodiments.

[0024] Such as figure 1 As shown, the test method of the regional backup automatic switching system under the environment of the main station computer room includes the following steps:

[0025] (1) Establish n simulated substations in the SCADA of the EMS system, n=1~+∞;

[0026] (2) Establish a simulation environment in the computer room of the main station to simulate the grid faults in each simulated substation respectively. The simulation environment includes a GPS time synchronization trigger device connected in sequence, a station-side dynamic model tester for simulating substation fault data, The measurement and control device used to collect fault data, the remote control device used to send fault data to the simulated substation, and the GPS time synchronization trigger device simultaneously triggers the dynamic model tester at each station to simulate the subst...

Abstract

The invention discloses a method for testing an area spare power automatic switching system in an engine room environment of a master station. The method comprises the following steps of: (1) establishing a plurality of simulation substations in a supervisory control and data acquisition (SCADA) system of an engine management system (EMS); (2) establishing a simulation environment in an engine room of the master station for simulating an electric network failure in each simulation substation, and correspondingly sending simulated electric network failure data to each simulation substation; (3) connecting the simulation substations with the failure data in series by a measured-area spare power automatic switching system to establish a chain type series connection model, outputting a motion processing method of area spare power automatic switching to the SCADA system, and displaying the motion processing method by using the SCADA system; and (4) comparing whether the motion processing method in the step (3) accords with an area spare power automatic switching motion processing method which is theoretically correct. By adoption of the method, the correctness and reliability of the motion processing method which is output by the area spare power automatic switching system can be guaranteed.

Description

technical field [0001] The invention belongs to the field of electric power system automation engineering, and in particular relates to a test method for an automatic switching system in an area in a main station machine room. Background technique [0002] Chinese invention patent (Application No. 201110020894.7) discloses a 110KV regional backup automatic switching action processing method based on the EMS system. The method includes embedding the regional backup automatic switching system in the EMS system, and the EMS system runs in the main station (power dispatching center) computer room , the regional backup self-commissioning system can automatically obtain the grid data of each substation in the EMS system, the regional backup self-commissioning system can automatically model the chain supply model, and use the real-time information such as remote signaling and telemetry of each substation collected by the SCADA system to judge The charging conditions, starting condi...
