Research on repetitive control method of DC active power filter in HVDC based on system identification
摘要
Abstract
The advantages and disadvantages of existing control methods for DC active power filter in HVDC system are analyzed, and based on the repetitive control method applied in AC active power filters, a system identification based repetitive control method is applied to DC active power filter in HVDC systems. According to the theory of repetitive control and system identification and combined with the simulation results of MATLAB/Simulink, the structure of the controller is optimized, so that the performance of the control system is effectively enhanced. The effects of different disturbance levels on the accuracy of identification, control parameters setting and system performance are comparatively analyzed, which present the system identification based repetitive control an effective control method for DC active power filter to suppress DC harmonic current in HVDC system.关键词
