Analysis on Fault Chain Risk of Power System

In the production process of the electric power system,some faults will appear because of the objective factors or subjective artificial factors.Serious power system faults chain will lead to stop running of the whole power system,cause widespread blackouts,so the power system fault analysis of chain is very necessary.In this context,the fault reasons for the chain and the main influence factors are analyzed.Then the risk analysis method and principle of cascading failure are introduced.At last,the specific application of the risk assessment method in the power system is introduced.
