Problems solved by technology
[0003] However, the action processing signal sent by the regional backup automatic switching system often makes mistakes after passing through the telecontrol channel between the actual substation and the main station, which also causes the regional backup automatic switching system to obtain wrong substation fault data, which brings great harm to the safety of the power grid. In addition, if there is a malfunction without testing, it may cause a large-scale power outage; if the series supply line or transformer is repaired by someone, it may also cause the danger 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, a practical test method for the regional backup automatic switching system in 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 at the site of each substation to simulate grid faults in each simulated substation respectively. The simulation environment includes a GPS time synchronization trigger device connected in sequence, and a station-side dynamic model tester for simulating substation fault data , The original measurement and control device in the substation used to collect fault data, the telecontrol device used to send fault data to the simulated substation, and simultaneously trigger the dynamic model tester at each station through the GPS time synchronization trigger device located in e...

The invention discloses a test method for the field band channel operation of an automatic bus transfer system of an area network, comprising the following steps of: (1) establishing a plurality of simulated substations in an SCADA (Supervisory Control and Data Acquisition) system of an EMS (Energy Management System); (2) establishing a simulated environment in each substation on site to respectively simulate power grid faults in each simulated substation, and respectively and correspondingly sending simulated power grid fault data to each simulated power substation through telecontrol channels; (3) serially connecting all simulated substations with fault data by an automatic bus transfer system of a tested area to establish a chain series model, outputting an action processing method of automatic bus transfer of an area to the SCADA system, and issuing automatic bus transfer actions of areas to the simulated substations by the SCADA system; and (4) comparing whether the actual action conditions in the step (3) are consistent with the theoretically correct automatic bus transfer action conditions of the areas. By using the test method, the accuracy and the reliability of the action processing method output by the automatic bus transfer system of the area can be ensured.
