摘要
在详细研究双馈风力发电机功率解耦控制的基础上,利用PSASP/UD模块搭建了双馈风机的稳态潮流模型以及三阶暂态模型,并基于传递函数辨识的方法及最小二乘法求解出风力发电机的5个动态等值参数。建立了3个地区的双馈大型风电场,并接入电网进行了潮流、短路容量、系统调峰能力3种稳态计算,以及短路、切机等多种故障下的暂态稳定性仿真。结果表明:基于PSASP/UD的双馈风机仿真模型合理准确,有效地模拟了大型双馈风电场的动态性能。
Based on the analysis of power decoupling control of DFIG（Doubly Fed Induction Generator）,its power flow model and third- order transient model are set up with PSASP/UD module. Five dynamic equivalent parameters are calculated using the identification method based on transfer function and the least square method. Three large wind farms are established and connected to power grid. Three steady state calculations（power flow,short- circuit capacity and regulating capability） are carried out,as well as the transient stability under different faults（short- circuit,machine shedding,etc.） is simulated. Results show that the DFIG model based on PSASP/UD is reasonable,accurate and effective for its dynamic performance simulation.
