| Abstract: | An automatic random simulation of the voltage sag based on Monte Carlo method and the multiple package of PSCAD/EMTDC is presenfed.The Monte Carlo model of the information of voltage sag is built,which is implemented in PSCAD/EMTDC,by taking sample of the fault information by Multiple Run package.Then the distribution of sensitive load nodes voltage sag characteristic parameters and sag energy indices are derived.The simulations based on the proposed model agree with the real case of a company grid,which de... |
