The invention relates to a method for evaluating intelligent alarming of a substation monitoring system. The method comprises: step one, an instantiated fault sequence test case file conforming to a fault alarm information format is generated by a fault serialization module and a monitoring system gives a fault brief report; step two, comparison and evaluation on the fault brief report and the instantiated fault sequence test case file to obtain a single fault comparison test result; and step three, statistics of a passing rate of testing faults of the monitoring system is carried out; if thepassing rate is larger than a set value, the intelligent alarm function of the monitoring system passes the test; and otherwise, the intelligent alarm function of the monitoring system is below standard. Therefore, the operation staff is able to obtain a fault analysis result quickly, accurately and efficiently.
