提出了将基于基波磁通补偿(FMFC)原理的串联混合型有源电力滤波器(SHAPF)应用于中高压系统。介绍了有源电力滤波器的滤波原理、串联变压器的设计,以及逆变器的设计和控制。样机实验结果表明:该有源滤波装置的滤波效果良好、可靠性高,同时该SHAPF的谐波压降对负载供电的影响很小;只投入有源滤波器,而没有投入无源滤波器时,仍然有较好的滤波效果。该技术可应用于电压更高、容量更大的电力系统。
A series hybrid active power filter (SHAPF) based on the principle of fundamental wave flux compensation (FMFC) is proposed for medium and high voltage systems. The principle of active power filter, the design of series transformer and the design and control of inverter are introduced. The experimental results of the prototype show that the filtering effect of the active filtering device is good and the reliability is high. At the same time, the harmonic pressure drop of the SHAPF has little influence on the load power supply; only the active filter is put into operation without the passive filter , There is still a good filtering effect. The technology can be applied to higher voltage, larger power systems.
