无功与电压控制方式对双馈风机轴系的暂态稳定性影响

摘要

Control strategy for active power, reactive power and voltage based on the PI control for the rotor side of the wind turbine generator is presented. An equivalent two mass-model for doubly fed induction shaft system is established. In the Matlab/simulink Simulation platform, the power system simulation model of a wind farm is built, and the transient operating mode of the system is simulated under the condition of the reactive power and voltage control mode of the doubly fed wind farm.%针对双馈风电场的不同控制策略对轴系暂态特性的影响，提出了基于PI控制的双馈风电机组转子侧的有功、无功、电压控制策略。搭建双馈风机系统等效二质量块数学模型。在Matlab/simulink搭建了某风电场的电力系统仿真模型，对无功、电压控制模式下轴系暂态运行工况进行仿真，验证了所提控制策略的正确性与有效性。
