摘要：
In conjunction with Xiamen flexible DC power transmission demonstration project, the scheme and engineering application of flexible DC control and protection system are researched, including the hierarchical structure of control and protection system, the basic control strategy of the pole control system, structure of control system, the interface features between the pole control system and the valve control system and the configuration of the DC protection system function. In order to verify the work correctness between the pole control system, the valve control system and the converter valves, and prevent large current appearing for the first time de-blocking from damaging the converter valves, this paper puts forward the passive inverter test scheme for the true bipolar topological structure system. Field test results have proved the validity of the triggering phase sequence by valve groups, fully compensating for the time delay of the control system. The results of reactive power and active power step test show that the control system meets the performance requirement on rapidity, reliability and flexibility. The results of DC protection trip test show that the logic function is correct, the converter valves are blocked correctly and the breaker trips correctly. © 2016 Automation of Electric Power Systems Press.
