Research on Analysis,Management and Early Warning System for Grid Connection Status of Thermal Power Units
Real time operation parameter monitoring of thermal power unit equipment can provide timely warning for abnormal states of the equipment,and provide corresponding warning guidance measures to maintain the healthy and stable operation of the thermal power unit,while indirectly maintaining the stability of the power grid.However,in practical applications,the analysis of the grid connection status of units often has strong uncertainty.From the physical description of the system side,modeling of complex equipment is difficult,and there are many coupling variables between parameters.This article focuses on the research of early warning and diagnostic methods for grid connected state analysis based on evidence driven theory.Firstly,the basic principles of D-S evidence theory are analyzed.Secondly,the mechanism of grid connected analysis and early warning for thermal power units is presented,and the functional points of system management and data analysis are summarized.Finally,a hardware equipment design scheme is provided,providing reference and guidance for high-quality equipment management and grid connected operation of thermal power units.
