以电流源型和电压源型变流器作为研究对象。探讨了可对电流源型变流器和电压源型变流器交流侧电流的幅值和相位进行有效控制的SPWM开关策略。在此基础上,研究了能够按照系统要求对2种超导磁储能装置进行有功和无功功率调节的功率控制方法。仿真结果表明所研究的功率调节方法能够在四象限内进行超导磁储能装置输入输出有功和无功功率的快速解耦控制.仿真同时验证了所研究的功率控制策略的正确性和可行性。
A strategy of SPWM switching is discussed,which can be applied to effectively control the amplitude and phase of current at AC side of current source converter or voltage source converter,and a method of power control is studied,which can be applied to regulate the active power and reactive power according to the requirements of system for two kinds of Superconducting magnetic energy storage system. Simulative results show that,with the studied method of power regulation,the rapid decoupled control of the input/output active power and reactive power of superconducting magnetic energy storage system can he realized in four quadrants,verifying the correctness and feasibility of the DrODosed strategy.
