Electric power system operation standby reliability testing system

Abstract

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.

Description

technical field [0001] The invention relates to a system in the technical field of testing, in particular to a reliability testing system for power system operation standby. Background technique [0002] The fundamental task of a power system is to supply electricity to consumers as economically and reliably as possible. The modern power system is constantly developing towards high voltage, long distance and large capacity. The loss of system function due to random events will bring huge economic and social losses. With the increasing scale and complexity of power grid interconnection, large power outages at home and abroad occur frequently. A national survey report by the Electric Power Research Institute of the United States disclosed that the annual economic loss to the entire US economy due to power system outages is as high as 104 billion to 164 billion US dollars. Since 2003, major power outages such as "8.14" in the United States and Canada, and "8.28" in London hav...

Problems solved by technology

Its shortcomings are that (1) the rated capacity of the unit is used to determine the upper limit of the system’s available reserve, without considering the impact of the real-time operating state on the upper limit of the unit’s available capacity; (2) no data collection interface with the daily operation plan has been established, so only the EMS system can be tested The real-time operation status cannot test the reliability of the daily operation plan formulated by the dispatcher; (3) the method in the literature is only tested for the IEEE-RTS test system, and the proposed algorithm can only be tested for small-scale power systems, while With the interconnection of power systems and the expansion of scale, its algorithm cannot be applied to systems with more than 5,000 nodes similar to the East China Power Grid, and cannot be applied to the reliability test of large regional power grids; (4) The actual power system is operated in partitions, and the reliability test In addition to considering the reliability of the entire network, it is also necessary to reflect the influence of the reliability of each partition on the reliability of the entire network. This method only tests the entire network and cannot reflect the influence of the reliability of each partition on the reliability of the entire network; ( 5) The scheme design is only proposed from the perspective of algorithm, and no real application examples have been formed
