摘要

首先,根据虚拟惯性时间常数对风电机组惯性支撑能力进行定量表征,进而分析转矩控制器参数对虚拟惯性时间常数的影响。在此基础上,提出一种自适应下垂控制与转矩控制器模糊自适应控制相结合的频率综合控制策略,实现对虚拟惯性时间常数的灵活调整,在抑制系统频率快速变化的同时,加快频率恢复,并可有效解决频率二次跌落问题。最后通过仿真验证所提控制策略的有效性以及对频率二次跌落的改善作用。

Abstract

In this paper, a quantitative representation of the inertial support capability of wind turbines based on virtual inertia time constant is presented, and then the influence of torque controller parameters on the virtual inertia time constant is analyzed. On this basis, an integrated frequency control strategy combining adaptive droop control and fuzzy adaptive control of the torque controller is proposed to achieve flexible adjustment of the virtual inertia time constant, which can accelerate the frequency recovery while dampening the rapid change of the system frequency and effectively solve the problem of secondary frequency drop. Finally, the effectiveness of the proposed control strategy and the improvement effect on the secondary frequency drop is verified by simulations.
