Prediction Analysis of Electromagnetic Interference Based on Gray Prediction Theory

摘要

The paper introduces a new method for prediction of electromagnetic compatibility in the power system,and use the Electromagnetic simulation software ATP.By comparing the actual test results to the simulation results,it is proved that electromagnetic transient simulation is reliable and effective.It also introduces the Gray prediction theory to predict the next Electromagnetic Interference (EMI) of the substation.It is high practical to research and analyze the substation electromagnetic compatibility,and feasible to use the Gray prediction theory with multivariable for the model EMI prediction analysis.
