摘　　要：与常规直流输电不同,柔性直流输电换流阀子模块具备更为复杂的本体控制保护功能。以往的柔性直流输电控制保护设备联调中,重心往往集中在极控、阀控等上层控制保护设备,对子模块本体控制保护功能以及阀控相关的配合控制保护功能验证较少,特别是对实际运行中的子模块的保护功能很难加以验证,给工程运行带来故障隐患。设计了一种柔性直流输电换流阀子模块故障模拟系统,可实现对子模块故障的在线模拟,以验证子模块中控板和阀控相关的控制保护功能正确性。Unlike conventional direct current transmission,the flexible direct current transmission converter valve submodule has a more complex body control protection function.In the past joint adjustment of flexible direct current transmission control and protection equipment,the center of gravity is often concentrated in the upper control and protection devices such as pole control and valve control.The sub-module body control protection function and the valve control related coordination control protection function are less verified,especially for the protection function of the sub-module in actual operation is difficult to verify which brings hidden troubles to the engineering operation.A flexible direct current transmission converter valve sub-module fault simulation system is designed which can simulate the faults of the sub-module to verify the correctness of the control and protection functions related to the control panel and valve control in the sub-module.
