双馈风电机组总体控制策略及运行性能
Overall control strategy and operational performances of a doubly fed wind turbine generator system
摘要
Abstract
In order to comprehensively and correctly analyze the real-time operational characteristics of a grid-connected wind turbine generator system,it is necessary to analyze the overall control strategies and operation performances of the wind turbine generator system.According to the type of a doubly fed wind turbine generator system,the mathematical models of wind turbine,drive train and doubly fed induction generator（DFIG） are presented.From the viewpoints of the maximum wind energy capture and safe operation of the wind turbine,a maximum power output control strategy is proposed by considering the DFIG loss minimization,and a variable pitch control strategy is also presented by considering generator rotational speed restriction and the output power restriction.Combined with a power decoupling strategy of DFIG,the overall operational performances of the doubly fed wind turbine generator system are simulated.By comparing the simulation,theoretical analysis and actual operational data,the results show that the presented model and overall control strategies of the doubly fed wind turbine generator system are valid.关键词
