[Abstract]:In order to solve the parameter optimization problem of HVDC control system, a parameter optimization method based on joint call of PSCAD-MATLAB is proposed. This paper expounds the possibility and basic principle of joint call, and introduces the basic flow of realizing optimization of joint call. Using CIGRE standard test system as the research model, the parameters of Pi controller in rectifier side constant current control are optimized by improved particle swarm optimization (PSO) algorithm. After comparing the original parameters, the results based on the transfer function optimization method and the joint call optimization based on the basic particle swarm optimization algorithm show that the joint call strategy accurately reproduces the actual working performance of the DC system. Based on the improved particle swarm optimization (PSO) algorithm, the parameter optimization of HVDC control system is realized effectively, and the transient and steady performance of HVDC system is improved. The joint call of optimal control parameters provides an important reference decision for the tuning and optimization of each parameter of HVDC control system.
