摘　　要：文中建立了风电场的稳态分析模型,该模型考虑了风电场的尾流效应、风电机组输出功率与尖速比和滑差等之间的函数关系,结合异步风力发电机工作原理,将异步风力发电机的滑差修正量引入到雅可比矩阵中,使潮流计算迭代过程仍保持牛顿-拉夫逊法所具有的平方收敛速度;还在该模型和常规 PQ 模型基础上提出了简化模型。文中将所提出模型用于接有风电场的 IEEE14 节点测试系统的潮流计算,并对结果加以对比分析。This paper introduces the steady-state model of wind farm, which considers weak effect of wind farm and the function among output power of wind turbine generator, tip speed ratio and slip etc. Since slip correction of asynchronous wind generator is imported into Jacobi matrix by virtue of operational principle of asynchronous wind generator, this method retains Newton’s quadratic convergence during iterative solution of load flow. In addition, predigestion model is introduced based on this model and conventional PQ bus model. These models are applied to calculate load flow of IEEE 14-bus test system including wind power generation and the results are analyzed contrastively.
