摘　　要：针对传统VSC系统使用的双闭环PI控制系统存在的PI参数多且整定困难,系统响应时间长等问题,提出了一种基于VSC-HVDC整流侧的有功、无功功率控制策略。详细描述了该控制策略的实现过程,并结合仿真实例进行说明和验证。在MATLAB中搭建了向无源网络供电的VSC-HVDC整流侧系统,对整流侧的有功功率、无功功率进行仿真分析。仿真结果表明,与传统的双闭环PI控制系统相比,提出的控制策略具有更好的动态响应性能。The dual closed-loop PI control system used in the traditional VSC system has many PI parameters and is difficult to set.The system response time Long and other issues,proposed an active and reactive power control strategy based on the VSC-HVDC rectifier side.The realization process of this control strategy is described in detail,and the simulation examples are used for explanation and verification.A VSC-HVDC rectifier side system for supplying power to the passive network was built in MATLAB,and simulation analysis was performed on the sudden increase of reactive power and the sudden increase of DC voltage command on the rectifier side.The simulation results show that the proposed control strategy has better dynamic response performance than the traditional double closed-loop PI control system.
