本文着重研究基于同步旋转坐标系下电压源型高压直流输电的暂态数学模型,提出一种采用极点配置理论设计的电压源型高压直流输电系统的控制器。基于状态反馈线性化的逆系统方法,推导了电压源型高压直流输电系统的逆系统模型,并构造出伪线性系统,实现了对电压源型高压直流输电系统有功功率和无功功率的解耦,最后采用极点配置方法对该伪线性系统进行综合,设计了相应的控制器。仿真结果表明,基于逆系统理论采用极点配置方法设计的控制器在大扰动下的动态响应特性优良。

This paper focuses on the research on the transient mathematical model of VSC-HVDC transmission in a synchronous rotating coordinate system,and proposes a VSC-HVDC system controller designed by pole configuration theory.Based on the inverse system method of state feedback linearization,the inverse system model of the VSC-HVDC transmission system is deduced,and the pseudo-linear system is constructed to realize the decoupling of the active power and reactive power of the VSC-HVDC transmission system.Finally,the pole configuration method is used to synthesize the pseudo-linear system,and the corresponding controller is designed.The simulation results show that the controller designed with pole placement method based on the inverse system theory has excellent dynamic response characteristics under large disturbances.
