Then using the simulation models of wind turbine and generator, the models of the overall wind power grid-connected systems using voltage-source inverter and current-source inverter are made. 基于上述仿真模型,分别建立了整个电压源型逆变器并网风力发电系统和电流源型逆变器并网风力发电系统的仿真模型。
Variable speed wind turbine 、 permanent magnet generator 、 three-phase AC-DC-DC-AC converter as well as transformer, are introduced in the thesis for establishing variable-speed wind energy conversion systems. 本文采用了变速风力机,永磁发电机,三相AC-DC-DC-AC变流器,变压器等构建了变速风力发电系统。
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。
