摘要
将载波移相正弦脉宽调制(CPS-SPWM)电压控制法中的载波移相方法应用到三角波比较电流控制法中形成一种新的控制方法——三角波移相电流控制法。通过简化模型的simulink仿真结果详细介绍了三角波移相电流控制法的基本原理。通过simulink仿真,论述了三角波移相电流控制法应用于STATCOM的可行性及优越性。对比了采用CPS-SPWM电压控制法和采用三角波移相电流控制法的STATCOM在输出电流和暂态响应上的不同。
The feasibility of CPS - SPWM voltage control applied to the carrier phase - shift current control method is discussed. Through the simulink simulation results of the simplified model, the basic principles of carrier phase - shift current control are introduced in detail. Through simulink simulation, the feasibility and superiority of the carrier phase - shift current control are discussed when being applied to STATCOM. The differences in output current and transient response are compared when CPS - SPWM voltage controling STATCOM and when the carrier phase - shift current controling STATCOM.
