摘要

针对传统PI控制器参数固定、适应能力不足,在风电机组转速恢复阶段易造成二次频率跌落深度较大的问题,提出一种面向弱化二次频率跌落的风电机组转速恢复策略。首先,分析电力系统频率动态响应特性,重点研究风电机组在调频与转速恢复阶段对频率响应特性的影响;其次,提出基于模糊PI控制的风力机转速恢复策略,设计模糊规则兼顾风力机转速快速恢复与弱化二次频率跌落;最后,基于Matlab/Simulink仿真软件搭建含风电的系统模型进行仿真分析,仿真结果验证所提策略在释放相同转子动能下,具有更快速的转速恢复特性以及弱化频率二次跌落效果的可行性。

Abstract

The traditional PI controller has fixed parameters and weak adaptability in different scenarios, and the speed recovery process is easy to cause the problem of large secondary frequency drop depth. To this end, this paper proposes a wind turbine speed recovery strategy for mitigating secondary frequency drop based on fuzzy PI controll. Firstly, the frequency dynamic response characteristics of power system are analyzed, and the influence of wind turbine on frequency response characteristics in frequency regulation and speed recovery stage is studied. Secondly, a wind turbine speed recovery strategy based on fuzzy PI control is proposed, and fuzzy rules are designed to take into account the rapid recovery of wind turbine speed and the mitigation of secondary frequency drop. Finally, based on Matlab/Simulink simulation software, a system model with wind power is built for simulation analysis. The simulation results verify that the proposed strategy has faster speed recovery characteristics and the feasibility of weakening the secondary frequency drop under the same released rotor kinetic energy.
