OPENING SIMULATING SYSTEM Of DYNAMIC CHARACTERISTICS OF RELAY PROTECTION

It is economical and convenient to analyze and checkout the actions of relay protection during a given fault in actual electric power system by a relevant simulating software,and at the same time,this kind of software is also efficient in analyzing and improving the operating characteristic of protection,and designing a new protection device.This paper proposes an application software,which is based on opening simulating system of dynamic characteristics of relay protection,including a formula editor that can realize any self defined operating equation of relay protection.Its input signals are obtained from the recorder data of Comtrade format in spot or the output data of transient electronic emulating software such as EMTDC,and it emulate conformable to the action equation and action characteristics,and show the emulating result by using graphics.It is proved that the software is convenient and the emulating results are correct and reliable.
