摘要:
含双馈风电机组(DFIG)的风电场经串联电容补偿线路并网可能会引发次同步振荡,为了提高该系统的稳定性,在复转矩系数法分析的基础上,该文设计了采用粒子群优化策略的附加阻尼控制器来抑制振荡的发生。该控制器以转子转速偏差为输入信号,经增益移相等环节后加入转子变流器的外环中,采用电气阻尼最低点的频率和需要补偿的角度计算附加阻尼控制器移相环节的时间常数,然后采用粒子群寻优算法对控制器的时间常数和增益实现优化。结果表明,基于粒子群优化后的附加阻尼控制器可以更好地补偿系统的电气阻尼,有效地抑制双馈风力发电场的次同步振荡,使风力发电系统的稳定性得到改善,同时克服了传统阻尼控制器只对单一工况有效的缺点,增强了系统的自适应性。
Abstract:
Considering sub-synchronous oscillation caused by the doubly-fed induction generator(DFIG)-based wind farm interconnected with series compensated electric network,an additional damping controller combined with the particle swarm optimization is designed to improve the stability of the system based on the analysis of complex torque coefficient method. The controller takes the rotor speed deviation as the input signal,which is added to the outer control loop of rotor converter through the gain link and phase shift link. The frequency of the lowest point of the electrical damping and the angle needing to be compensated are used to calculate the phase-shifting parameters of the additional damping controller. The time constant and the gain of the additional damping controller are optimized by the particle swarm intelligence algorithm. According to the resnlt of the simulation,the damping controller based on the particle swarm optimization has a good effect on system electrical damping compensation and sub-synchronous oscillation suppression of DFIG-based wind farms,thus improving the stability of the wind power system.
