摘要
为研究变速恒频双馈风电系统的各种高性能控制策略提供有效的动态仿真与分析平台,并克服Matlab仿真环境下所建的模型在动态性能方面存在的不足,采用PSCAD仿真软件建立了变速恒频双馈风电系统的动态仿真模型。基于PSCAD的变速恒频双馈风电系统模型由风机、双馈发电机、功率变换器、控制模块构成,在建立的模型基础上,针对电网电压正常情况以及电网电压发生对称、不对称故障时系统的运行特性进行了仿真研究,仿真结果证明了系统模型的正确性。
To establish an efficient simulation and analysis plant of studying some high performance control strategies for variable speed constant frequency doubly-fed wind power generation system, a dynamic simulation model of variable speed constant frequency double fed wind power generation system was established by PSCAD simulation software. The designed system model based on PSCAD overcomes the weak points of dynamic performances of the model based on Matlab. The variable speed constant frequency doubly-fed wind power generation system based on PSCAD consists of wind turbine, doubly-fed generator, power conver, control module. Based on the designed model, system operating performances are studied under normal voltage, unsymmetrical and symmetrical voltage fault. The simulation results show the correctness of the established system model.
