摘要
介绍了状态空间平均法的基本原理;通过引入开关函数,建立了统一电能质量调节器中串联变流器的数学模型;基于状态空间平均法建立了串联变流器单相逆变器的状态空间平均模型;采用Matlab和Multisim软件对该模型进行了仿真。仿真结果表明,该模型能较好地反映变流器系统的状态变化,具有一定的合理性。
The basic principle of state-space averaging method was introduced,the mathematical model of series converter in UPQC was built by use of switch function,the state-space averaging model of single-phase inverter of series converter was built based on state-space averaging method,the Matlab and Multisim softwares were applied to simulate the model.The simulation results showed that the model can reflect state changes of converter system and has certain reasonableness.
