摘要
随着对可再生能源利用规模的不断扩大,我国风电的装机容量迅速增加,这将给电网的安全稳定运行,系统的发供电平衡以及调峰调频带来越来越多的问题。鉴于此,吉林省电力有限公司与东北电力大学合作进行了风机建模和风力发电对电网动态行为影响的评价研究。为获得双馈风电机组的真实特性以及校验所建模型的准确性,进行了我国首次接于实际电力大系统中的风电场短路试验。本文给出了基于PSCAD/ EMTDC仿真平台的两相旋转坐标系下的双馈感应风电机组电磁暂态模型,并利用该模型模拟联网运行双馈感应风电机组稳态运行及系统发生故障时的动态行为,通过对实测波形和仿真波形的对比分析验证了所建模型的有效性。
More and more wind farms will be built in China for better use of renewable energy, which may bring lots of problems tor balance of generation and supply, peak-load regulation and frequency regulation, as well as for security and stability of power system. Supported by Jilin Electric Power Co. Ltd and Northeast Dianli University, a project has been carried out to study wind turbines and the effects of wind farms on power system. To obtain the real characteristics of doubly-fed induction generators and verify the model, the first field tests of wind farm in our country is conducted. In this paper, Employing Electro-magnetic transient Model of DFIG in Synchronously Rotating Frame, Replay simulation of field test is conducted under PSCAD/EMTDC.The identity between the simulation and experimental results verifies validity and correctness of proposed simulaiton model and the corresponding parameters.
