[0002] The control system is an important factor that determines the effectiveness of the power quality control device. In recent years, due to the continuous increase in the number of power units and current density of the power quality control device, the working environment has become worse and worse, resulting in some of the original control systems. Under such operating conditions, the anti-interference ability is not strong, the sampling accuracy is not high, and the fault protection mechanism is not strong enough, which leads to the low control performance of the system and the unreliable operation of the power quality control device.

Description
technical field [0001] The invention belongs to the technical field of power electronic device control, and more specifically, relates to a control system for a multi-state electric energy quality control device. Background technique [0002] The control system is an important factor that determines the effectiveness of the power quality control device. In recent years, due to the continuous increase in the number of power units and current density of the power quality control device, the working environment has become worse and worse, resulting in some of the original control systems. Under such operating conditions, the anti-interference ability is not strong, the sampling accuracy is not high, and the fault protection mechanism is not strong enough, which leads to the low control performance of the system and the unreliable operation of the power quality control device. Contents of the invention [0003] The purpose of the present invention is to overcome the deficienci...
