Description

technical field [0001] The invention relates to a static synchronous compensation device. Background technique [0002] Traditional reactive power compensation technologies such as synchronous condensers, capacitors, etc., are limited by their principles and implementation methods, and cannot provide practical and efficient solutions for fast dynamic reactive power compensation. Although static compensation devices such as SVC can realize continuous and fast compensation, they still use capacitance / reactance to provide reactive power in essence, so the compensation characteristics will be limited by the system working conditions, and the compensation current generated by it has high harmonic content, and even must Equipped with filter. [0003] The filtering effect of traditional passive filtering devices is closely related to system operating parameters, affected by changes in system harmonic characteristics (impedance / short-circuit capacity) and system voltage, the applic...
