一种风机频率稳定控制器的设计及仿真实验.

In this paper,the problem of frequency support capability for doubly fed induction generators (DFIGs) in the future grid with high penetration of wind power is discussed, and a frequency stability controller based on maximum power tracking control and differential control is proposed. The relationship between grid frequency and frequency support capability of DFIGs is built, then the influence of the designed controllers on system frequency stability is analyzed. And the power system simulation software DIgSILENT/PowerFactory is used to set up the system simulation experiment platform, the result proves that the proposed frequency stability controller can effectively improve the frequency performance of the whole system.
