Abstract

Around the phenomenon of cascading trip in power grid, a method of evaluating it was researched. Firstly, aiming at the backup relay protector of current type, by comprehensive analyzing the action of the relay protector and the power flow distribution in power system, this paper analyzed the relationship between cascading trip and nodal injection power. Base on this, a method of evaluating cascading trip was proposed. This method uses pattern recognition technology and takes the nodal injection power of power grid as the feature input. In order to prove the rationality and effectiveness of this method, some examples with IEEE39 system were shown and the results were satisfactory.
