Uniform Control Method of Gird-connected Generation and Active Power Filtering

根据并网逆变器和电力有源滤波器具有相同主电路结构的特点,提出了并网发电和电力有源滤波的统一控制方法。采用该方法的分布式电源同时具有并网逆变器和电力有源滤波器的功能,既可充分发挥分布式发电的优越性,又能大大改善电网的质量。通过理论分析、仿真和试验,验证了该方案的可行性。

Based on the same main circuit configuration of gird-connected inverter and active power filter,a uniform control method of gird-connected generation and active power filtering is presented.Using this uniform control scheme, the generator can work as gird-connected inverter and active power filter simultaneously,which exerts the advantage of distributed generation,and improves the grid quality.Theoretic analysis,simulation and experiment proved the feasibility of this scheme.
