摘要
研究风电并网后的电力系统潮流计算方法,有利于确定风电场的并网方案,并为进一步研究其对系统稳定性、可靠性等方面的工作提供基础。在异步风电机组的传统RX模型基础上将风电机组无功功率表示为电压的函数,消去转差的影响,避免传统RX模型算法中的两个迭代过程,牛顿迭代法仍平方收敛,结合已有潮流计算确定风机并网的潮流计算模型,计算分析了不同风机模型对系统潮流的影响。
The study of power flow calculation method after integration of wind power is helpful in determining integration scheme of wind farm and in providing foundation for the further study in such aspects as system stability and reliability etc. Based on the traditional RX model of asynchronous wind power unit, reactive power of the wind power unit is expressed as the function of voltage so to eliminate the influence of rotation tolerance and to avoid the two iteration process in the conventional RX model algorithm and retain the quadratic convergence speed of Newton iteration method. The power flow calculation model of wind farm integration is defined with combination of existed power flow calculation and the influence of different wind farm model on the system flow is calculated and analyzed.
