Abstract
In order to solve the problems such as the computational complexity of each harmonic component of VAR compensator's compensation current based on AC chopper and the poor control precision,a frequency domain model of the system is established with a single-phase dynamic capacitor based on BOOST AC chopper as research object. A lo?cal sensitivity analysis method is presented,and the closed loop control of grid-side reactive power and harmonic cur?rent are realized using a closed-loop control algorithm based on the theory of synchronous reference coordinates.Com?pared with the existing numerical model,the proposed method can analyze the relationship between the duty cycle,reac?tive power compensation current and harmonic current more precisely,thus the performance and reliability of the sys?tem is improved.The feasibility and effectiveness of the proposed model and control strategy are validated through sim?ulation and experimental results.关键词
