| Abstract: | As large scale application of microprocessor-based protection and integrated automatic system in power system,these micro-electronic elements are very sensitive to interference,especially when lightning happens,power interference is caused and serious damage to a station occurs in a station.So it is necessary to analyze lightning accident and power interference caused by lightning in microprocessor-based protection and integrated automatic system.On the basis of research on cause,approach and modus of power interference,especially conductive interference to microprocessor-based measure and control circuit and inductive interference to a secondary system,appropriate models are established,and finally technology measures are proposed. |
