摘　　要：提出了考虑暂态稳定约束的最优潮流(OTS)问题的计算方法。从时域的角度来考虑暂态约束问题,将约束表示为暂态过程中某个时刻的最大功角之差;而用仿真的隐式梯形积分形式来处理约束函数的梯度问题,将梯度的求解转换成一个代数迭代的过程。这样有效地减小了问题的规模和复杂程度。用IEEE39系统对该方法进行了测试,表现出良好的收敛效果和数值精度,验证了该方法的有效性。An algorithm for OPF with transient stability constraints is presented. Based on the form of the trapezoidal rule for time domain simulation, the transient stability constraints is expressed to be the maximum value among the angular separations between any of two machines at the specified time instance, and the jacobian matrices of transient stability constraints is given in the form of iterative algebraic operation. The test on the IEEE-39 system verified its effectiveness of approach with good convergence and precision for numerical calculation.
