摘　　要：针对同步发电机常用模型，引入新的状态变量，改变了网络代数方程的形式，在计算过程中既不需要迭代，也不需要进行三角分解，从而使仿真计算速度得到很大提高，且计算量随电力系统阶数的增大而增加很慢。对一个５机２５母线系统进行的仿真计算表明，该快速算法比牛顿迭代法快２４倍多，比不诚实牛顿迭代法快１２倍多，而计算精度同样得到保证。A new fast simulation method of power systems is proposed in this paper. New state variables of synchronous generators are introduced in this new method. which can change the forms of the algebraic equations of network. so no iterations and no triangulation are performed during the simulations. thus the simulation speed can be largely increased. Simulations have been carried out on a 5-machine-25-bus system. the results showed that this new method is 24 times faster than Newton's iterativc method and 12 times faster than dishonest Newton's iterative method. And its accuracy can be guaranteed at the same time. Also. its computational burden is increased very slowly with the increment of power system order.
