[0048] In order to describe the present invention in more detail, the APF parallel system and its control method of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0049] Such as figure 2 As shown, an APF parallel system includes N APFs connected to the power grid and a detection control unit;
[0050] APF is used to inject compensation current into the grid; it is composed of a converter and a filter inductor; the grid side of the converter is connected to the grid through the filter inductor, and the DC side is connected with a DC support capacitor C dc ; The high voltage ends of all APF DC support capacitors are connected together, and the low voltage ends of all APF DC support capacitors are connected together. The converter is a three-phase half bridge structure, and each bridge arm is composed of multiple IGBTs in parallel.
[0051] The detection control unit is used to collect the grid voltage u s...
