摘　　要：本文以节点注入功率和PV电压运行曲线为基础,形成720种运行方式,用概率潮流计算出各节点的功率、电压均值和协方差,作为功角特性分析的初始条件,基于隐式梯形积分法来进行暂态稳定计算。然后,以这720个运行方式为样本,分别进行每个运行方式下的功角仿真计算,求取均值作为准确值对概率算法进行验证。Based on operating curves of nodal injections power and PV nodal voltages, this paper forms 720 kinds of operating conditions, calculate power, voltage expectation and voltage covariance of each node. Consider these as the initial conditions of angle characteristic analysis, calculate transient stability based on the implicit trapezoidal integration method. Then, regard this 720 kinds of operating conditions as sample, calculate power angle of each mode separately, calculate the expectation as accurate value to validate probability algorithm.
