摘要

开发风电机组的控制潜力向电力系统提供频率控制成为对风力发电的新要求。传统的针对超速风电机组的频率控制方法没有考虑对风电机组旋转动能的有效利用，缺乏根据风电机组运行状态对频率控制器参数进行整定的方法，尚未充分发挥风电机组的频率控制能力。因此，提出了超速风电机组的改进频率控制方法，将超速风电机组的转子旋转动能用于降低系统频率变化率，超速减载功率用于系统一次调频，提出了考虑风电机组运行状态的频率控制器参数整定方法。仿真结果表明，提出的控制方法能够充分利用风电机组的旋转动能和减载功率提升系统频率控制效果，同时防止风电机组过度响应，有利于风电机组安全运行。

Abstract

It is a new requirement for the wind turbines to improve the control potential of wind turbines which contributes to the system frequency regulation. The effective utilization of the kinetic energy is not considered by the traditional control methods for the over-speed wind turbines

and the method of selecting controller parameters is insufficient according to the operation status of the wind turbines

which cannot make full use of the frequency control capability for the wind turbine. Thus

an improved frequency control strategy for the over-speed wind turbines is put forward. The kinetic energy from the wind turbines is used to reduce the rate of change of frequency

and the de-loaded power is utilized for primary frequency regulation. The method of selecting the controller parameters is proposed considering the operation status of the wind turbine. The simulation results show that the proposed method can fully use the kinetic energy and de-loaded power to improve the effect of frequency control in the system

and prevent the over-response of the wind turbines

which also ensure stable operation of the wind turbines.
