摘　　要：为了抑制高压直流输电系统的整流侧在故障恢复过程中出现过电流和过电压现象,基于南方电网科学研究院研发的交直流电力系统计算分析软件DSP(Dynamic Simulation Program),对整流侧最小触发角控制进行了研究。通过选取功率分量信号作为输入信号,并通过合理的控制逻辑与恰当的参数调节,设计出能够实现最小触发角控制功能的自定义模块。经仿真,验证了可实现抑制整流侧故障恢复中的过电流和过电压的目的。这对于实际直流输电控制系统有一定的借鉴意义。In order to suppress the over current and over voltage that occurs in the fault recovery process in the rectifi- er side of the HVDC transmission system, the minimum firing angle control of rectifier side is researched based on the DSP, which is developed by the Electric Power Research Institute of CSG. By selecting the power components signal as the input signal, through the reasonable control logic and the appropriate parameters adjustment, a custom block which can achieve the minimum firing angle control function is designed. The simulation results show that the purpose of suppressing the over current and over voltage in the fault recovery of the rectifier side can be realized. This has cer- tain reference significance to the actual HVDC transmission control system.
