The invention provides a power system weaknesses identification method based on a cascading failure. A cascading failure model is introduced into the state analysis of risk assessment. The influence of the cascading failure developed by an originating failure on a power grid is taken into account. The dynamic and cascading development law of a blackout incident is met. With the help of a cascading failure process, a weakness affecting the blackout incident is analyzed and identified. A key element in the blackout incident can be really screened out. An acquired weakness result is comprehensive, accurate and useful. According to the invention, the mature theory of risk assessment based on a Monte Carlo simulation method is effectively inherited; complex relationship derivation is not needed; failure enumerating is not needed; and especially for a large system, the advantages of the method provided by the invention are apparent.
