A Whole Process Simulation Method of Fault Information

Abstract

The invention relates to a method which simplifies system debugging complexity through designing and constructing a protection device simulation system, in particular, a fault information full-process simulation method. The fault information full-process simulation method is a supplement for traditional debugging in substation fault information system debugging. According to the fault information full-process simulation method, the correctness of all relaying protection information of a fault information system is verified in the substation fault information system debugging, wherein the relaying protection information of the fault information system is connected into a substation; a variety of performance indexes of the fault information system are detected; and based on the verification of the relaying protection device information, actual action fault scenes based on primary equipment states and maintenance status flags are simulated. With the fault information full-process simulation method of the invention adopted, complexity in system debugging can be greatly simplified, and batch debugging can be realized, and substation automated system integration testing efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of electric power system scheduling automation, and is particularly applied to the function test, stability test and expansibility test of power grid relay protection and fault information system. Background technique [0002] At present, the collection and processing of relay protection information is mainly realized through the fault information system, which includes the main station system and the substation system. The main station system is responsible for collecting the information of substation protection devices, and processing the information to form a complete protection action report; the function of the fault information system is mainly realized by the Baoxin sub-station, which is mainly responsible for receiving and processing the protection device information and sending it to the main station . [0003] According to many years of operation experience of the fault information system, fault information...
