The Research Of High Analysis Of Transformer Protection Based On The Relay Protection And Fault Information System

With the development of power system, microcomputer-based protective relay and fault recorder are used in power system widely. System of relay protection and fault information can process the data acquired from these devices. So system of relay protection and fault information can provide data information for operation of power system. High analysis based on the data information will improve the practicality and function of the system of relay protection and fault information. This paper introduces a method of high analysis of transformer protection based on the data from the system of relay protection and fault information. Making full use of the data information can supervise the function of the power system and analyze the action of relay protection after fault to achieve early-warning before fault and analysis after fault. Making full use of the data can increase the managing level of operation of power system.
