基于PID控制和改进粒子群优化算法的特高压直流附加次同步振荡阻尼控制器设计
Design of UHVDC Supplementary Subsynchronous Damping Controller Based on PID Control and Improved Particle Swarm Optimization Algorithm
摘要
Abstract
Taking the fast controllability of HVDC system into consideration, the model of supplementary subsynchronous oscillation damping controller (SSDC) on the basis of proportional-integral-derivative (PID) control was established to solve the potential sub-synchronous oscillation (SSO) problem in the sending end of ultra-high voltage direct current (UHVDC) transmission system from Xiangjiaba to Shanghai. A new method which combining mini-max value principle and improved particle swarm algorithm together is put forth so that the parameters of the controller could be designed and optimized conveniently. The time domain simulation results of different operation modes show that the SSDC designed is with strong robustness and can effectively restrain the shaft torsional vibration of steam turbine units.关键词
