摘　　要：本文对换流变压器有载调压开关定角度和定电压控制策略进行分析,针对两种策略的不足,提出兼顾两者优点的改进方法,通过迭代计算和Matlab/Simulink仿真验证了优化策略的可行性。结果表明,改进控制方法能够有效减少分接头动作次数,同时改善定电压控制模式下触发角的分布。In this paper,the fixed Angle and fixed voltage control strategies of OLTC in converter transformer are analyzed,and an improved method considering the advantages of both strategies is proposed.The feasibility of the optimal control strategy is verified by iterative calculation and Matlab/Simulink simulation.The results show that the improved control method can effectively reduce the tapping times and improve the distribution of trigger Angle under constant voltage control mode.
