摘　　要：随着清洁能源比重的增加,风电渗透率的增加,风电机组参与系统调频的任务越来越重要。目前传统的双馈感应式风力发电机参与系统的一次调频策略主要是减少转子动能和减载备用功率。针对传统调频策略的调频出力不足以及转速恢复导致频率二次跌落的问题,提出一种基于模糊控制的系数下的风电机组一次调频策略。在风机调频过程中,采用模糊控制对虚拟惯量系数和下垂系数进行整定,最后搭建仿真模型验证调频的效果。试验结果表明,模糊控制在调频时能有效提升调频出力,可减少转速恢复时的二次跌落,与传统的控制策略相比,能提升系统调频稳定性。As the proportion of clean energy increases and the penetration rate of wind power increases,the task of wind turbines participating in system frequency regulation becomes more and more important.At present,the primary frequency regulation strategy of the traditional doubly-fed induction wind turbine participating system mainly reduces rotor kinetic energy and load shedding standby power.In order to solve the problem of insufficient frequency regulation output of traditional frequency regulation strategy and secondary frequency drop caused by speed recovery,a primary frequency regulation strategy for wind turbines based on fuzzy control coefficients is proposed.In the process of fan frequency regulation,fuzzy control is used to set the virtual inertia coefficient and droop coefficient,and finally a simulation model is built to verify the effect of frequency regulation.The experimental results show that the fuzzy control can improve the frequency regulation output during frequency regulation,and reduce the secondary drop when the speed is restored.Compared with the traditional control strategy,it can improve the frequency regulation stability of the system.
