变速恒频风力发电机组动态稳定性仿真

Dynamic stability simulation of variable speed constant frequency turbine wind generator

以双馈风电机组为研究对象,介绍了双馈风力发电系统的基本结构.应用M atlab/S imu link搭建了双馈风电机组并网运行仿真模块,并对其在风速扰动下的动态稳定性做了仿真试验研究.结果表明双馈风电机组对风速的扰动有一定的适应能力,能保证系统的稳定运行.

The double - fed wind generator is taken as the study object and have introduced the double-fed wind power generation system of the basic structure. By use of Matlab/Simulink simulate the double-fed wind generator linked on the net and the dynamic stability is tested in wind perturbations. The results show that the doubly-fed wind generator has a certain degree of adaptability in wind disturbance and can stable operation of the system.
