摘要
根据双馈感应电机的特点,利用风电机组的数学模型,基于MATLAB/SIMULINK构建了包含风电场的电力系统的仿真模型。对风机的投入与切除,以及风电机组出口发生三相短路故障的两种情况进行了动态仿真。仿真结果表明,在风电机组0.8s接入系统和3.5s脱离系统时,系统略有波动但很快建立新的平衡;在风机出口故障时系统经历短期的波动后恢复了稳定,此结论为研究大规模风电并网提供了理论研究依据。
According to the characteristics of dual fed induction motor,using a mathematical model of wind turbine,power system simulation model including wing farm was constructed based on MATLAB/SIMULINK.The two dynamic simulations are carried out which including the cut-in and cut-out of the wind turbine and the three-phase fault occurs at the wind turbine＇s export.Simulation results show that when wind turbine cut-in the system in 0.8s and cut-out in 3.5s,there are slight fluctuations in the system but soon establish a new balance.The system restored stability after the short-term fluctuations in the case of occuring fault at the wind turbine＇s export.This conclusion provides a theoretical basis for the study of integration of arge-scale wind power.
