摘要
以双馈型风力发电机为主的风电场接入电网后,由于不同于同步发电机的异构电源形态,造成传统电力系统潮流算法在计算时会产生较大误差。针对这一问题,对双馈型风力发电机的电磁特性和控制策略进行了研究,进而描述风电场的输出特性,并在此基础上采用改进的电力系统潮流计算方法进行计算。结果表明,所采用的改进潮流计算方法效果良好。
After the wind farm with DF wind turbines is connected to the grid,due to the different heterogeneous power supply modes of the synchronous generator,the traditional power flow algorithm of the power system will generate large errors in the calculation.Aiming at this problem, the electromagnetic characteristics and control strategy of the DF wind turbine were studied,and the output characteristics of the wind farm were described.Based on this,the improved power flow calculation method for power system was adopted to make calculation.The results show that the improved power flow calculation method is effective.
