分析了开关试验站的工作原理和开关试验对电网的影响，建立了2013年华中电网机电暂态仿真模型和开关试验站电磁暂态仿真模型，利用电力系统全数字实时仿真装置（advanced digital power system simulator，ADPSS）进行机电-电磁混合仿真。由仿真结果可知，应禁止进行造成母线瞬时电压下降值大于15％母线额定电压的试验项目；开关网络试验项目不会造成邻近系统线路保护、母线保护、主变保护、电容器保护动作，但建议在保证灵敏度的前提下，适当提高母线差动保护和失灵保护的负序电压定值；各类开关试验项目均不会造成机组强励磁动作。

The working principle of switch test station and influence of switch tests on power system are analyzed. An electromechanical transient model for Central China Power Grid in 2013 and electromagnetic transient model of switch test station are built, and the hybrid electromechanical and electromagnetic simulation is carried out by advanced digital power system simulator （ADPSS）. Simulation results show that the test items, which cause the amplitude of voltage sag exceeding 15% of busbar rated voltage, should be forbidden; test items of switching network will not lead to the actions of line protection, busbar protection, main transformer protection and capacitor bank protection of adjacent system, however it is suggested to raise the negative-sequence voltage setting value of busbar differential protection and that of failure protection while enough sensitivity is ensured; various switch test items will not lead to the operation of generator forced excitation system.
