摘　　要：一般风电场系统潮流计算是在常规PQ模型的基础上设功率因数恒定。通过建立风电场稳态分析模型,结合常规PQ模型,提出采用异步发电机等值电路计算滑差和无功功率的新方法。在电力系统分析综合程序PSASP 6.28环境下,利用两种方法对包含风电场的电力系统潮流进行计算。仿真结果的比较表明了新方法计算量较小、收敛性较好,是可行的。其他新能源发电形式也可以通过这种方式融入PASAP的潮流计算中进行分析,具有很大的实用性。The flow calculation of wind farm is generally based on PQ model and the power factor of wind farm is considered as constant value. By the steady-state analysis of wind farm model, a new method for calculating the flow of wind farm based on PQ model is proposed herein, in which the equivalent circuit of asynchronous generator is used to calculate slip factor and reactive power. The flows of wind farm are calculated by using the two methods respectively under the environment of Power System Comprehensive Analysis Program PSASP 6.28. The comparisons of simulation results show that the new method has less calculation amount and a better convergence, and is practical. This method can also be used in the PASAP-based flow calculation of other new energy generation.
