Research and Development of Integration of Graph, Model and Database Tool in Power Plant Relay Protection Intelligent Setting Calculation System

In order to make the power plant relay protection setting calculation system more intelligent, Integration of Graph, Model and Database Tool (IGMD) are developed to implement primitive modeling, typical power plant design template modeling, text discription modeling and external pattern recognition modeling, among which typical power plant design template modeling and text discription modeling is semiauto and external pattern recognition modeling, based on the recognition of DXF files is supermatic. Reducing manual operation and improving efficiency, the IGMD has great value in both theory and practice.
