说明：  电力系统静态稳定计算一般采用小干扰法，即首先计算近似的线性微分方程组系数矩阵的特征根。然后根据特征根在复平面上的特性，判别电力系统运行的稳定性 操作说明： 请输入初始功率S0，形如a+bi 请输入无限大系统母线电压V0 请输入系统直轴等值电抗的大小Xd 请输入同步电角速度 请输入惯性时间常数Tj 请输入综合阻尼系数D
(static power system stability calculation generally use small interfering, first, calculate the approximate linear equations of the coefficient matrix eigenvalue. According eigenvalue in the complex plane on the characteristics of the identification operation of the power system stability operations : Please enter the initial power S0, shaped like a bi Please enter the infinite system bus voltage V0 Please enter the system straight axis equivalent reactance the size Please enter synchronous Xd Please enter the angular velocity-- inertia time constant Tj Please enter the integrated damping D)
