Electric power system operation standby reliability testing system

The invention relates to a power system operational back-up reliability test system which belongs to the technical field of computer applications, wherein: a data acquisition module realizes the data acquisition across security subareas by setting a data acquisition server; a basic information module carries out the update of basic information of the system; a data pre-processing module analyzes data in a file which is obtained by the data acquisition module and carries out the pre-processing of element operational data; an element outage rate calculation module dynamically updates the real-time element outage rate; a reliability test module determines the fault states of the system according to the element outage rate in the element outage rate calculation module and the reliability analysis data in the data pre-processing module and tests the fault states; an indicator calculation and output module carries out the statistics of the test results of the fault states in the reliability test module, tests the operational reliability of the system and outputs early warning information. The power system operational back-up reliability test system can comprehensively measure the operational reliability of the system and timely update the reliability information of the system based on the real-time operational information of EMS power grid.
