The variable speed wind turbine generator regulates the electrical power output by controlling the converter, and immits the damping active power associated with low-frequency oscillation to reduce the electrical power oscillation, increase the damping and reinforce the dynamic stability of the systems. 利用变频器控制系统对风电机组输出电磁功率进行快速控制,使变速风电机组向系统注入与低频振荡相关的阻尼功率,削弱系统功率振荡。
In this paper, the dynamic model of the variable speed wind turbine is established firstly, in order to analyze the impact of the wind generation on the system inertia and the power oscillation damping. 本文首先建立了变速风电机组的动态模型,进而分析高渗透率风电对系统惯性和阻尼的影响。
