| Abstract: | To solove the problem of slow calculating speed in analysing electric power system transient stability by the traditional hiding-trapezium method,the paper comes up with an improved method based on the SVR technology.The optimized method can not only maintain the intrinsic forecasting precision of power angle,but also largely reduce the iterative times and effectively accelerate the calculation.The improved method is very useful for real-time control of transient stability in modern large grid. |
