Abstract： |
This invention relates to continuous reactive compensator for electric network comprises: (1) testing circuit, for testing voltage of electric network phase current, phase load current and voltage of dc capacitor end of IGBT inverting arm; (2). regulatnig circuit, inputting above said items after variation into control circuit; (3). control circuit, according preset program, controlling bipolar transistor array of insulated gate to connect to or cut-off with dc capacitor, at the same time compensating electric network harmonic current and zero sequence current, and quickly incoming/outcoming reactive power with acting time of a few dozens millisecond, making electric net-work power factor being more than 0.99. It can also inhibit sudden dropping of voltage in electric network. |
