摘要: 通过模拟惯量控制策略,双馈异步风电机组(DFIG-WTG)可以实现惯量响应,提高电力系统的频率稳定性。综述了3类双馈异步风电机组的模拟惯量响应控制策略:一是在MPPT控制策略中引入频率偏差或其导数,通过增益、比例积分(PI)控制器等控制环节后,得到双馈风电机组转矩或有功功率的补充控制参考值;二是当发生频率扰动时,屏蔽MPPT控制策略,采用瞬时有功功率超发实现模拟惯量;三是采用磁链幅值相角控制(FMAC)策略实现模拟同步发电机控制。通过合理的参数设定,理论上3种控制策略均可以最大化利用风电机组的转子动能。

Abstract: Inertial response can be implemented on wind turbine generator (WTG) equipped with doubly fed induction generator (DFIG) via emulated control strategies to mitigate frequency deviation during power system transient process. Three types of emulated inertial response control strategies are reviewed in this paper. The first is to introduce frequency deviation or its derivative in the MPPT control strategy, and process it with emulated inertial control loop and output the supplemental control reference value of DFIG-WTG’s torque or active power. The second method provides short-time over production instead of MPPT control to emulate inertial response. The last method is to utilize flux magnitude and angle control(FMAC) strategy to operate DFIG-WTG in the way of synchronous generator, a different control strategy from traditional vector control. By setting reasonable parameters, the three methods mentioned above can effectively utilize the rotor’s kinetic energy.

Key words: wind turbine generator, inertial response, doubly fed induction generator, variable speed
