Testing system of thyristor converter valve control full link

The invention belongs to the technical field of direct-current transmission converter valves, and particularly relates to a thyristor converter valve control full-link test system which executes a control instruction of the test system through a valve control measurement and control module, sends an analog control signal to a to-be-tested valve control unit and detects a received state signal; a valve state simulation module simulates the states of different operation conditions, and sends a return signal of a converter valve simulation thyristor level and a state signal of auxiliary equipment to a to-be-tested valve control unit; and logic control is carried out through the monitoring module, and data processing is carried out on a test result of a simulation process, so that fault positioning and reproduction analysis are realized. Through mutual cooperation of the functional modules, various operation conditions of the converter valve control system are simulated, the problems of insufficient test means an
