摘　　要：针对风力发电变速恒频技术要求,笔者从简化的等值电路出发,分析了级联式无刷双馈电机的参数特性和稳态特性,使导出的结论大为简化,凸现了该种电机的主要参数与各种稳态特性特征的内在联系。阐述了该种电机发电运行的条件、发电机空载特性、自然功率特性与恒压频比控制特性,从而为该种电机用于风力发电及其采用压频比控制的研究提供参考。Accordimg to the demand of variable speed constant frequency wind-turbine generator, the parameter characteristics and some steady-state performances of cascade brushless doubly-fed machine are analyzed on the basis of a simplified equivalent circuit in this paper. Hence, the derived solutions are much concise so that the inherent relations of some steady-state performances with the main parameters are easily understandable. The conclusions such as the conditions for generator operation, the no-load characteristics, the characteristics of nature power and the behaviors of the machine under control of constant voltage/frequency ration derived in this paper are important for the further researching for application of the machine to wind-turbine generator.
