Abstract:Aiming at the faced problems of online monitoring and balance management for power and water quantity in fossil-fuel power station at present,this paper puts forward a design scheme for power and water quantity balance monitoring and informatization management system in fossil-fuel power station,which includes data acquisition,data processing,data display,fault diagnosis and alarm,safety trend analysis and other specific functions. And a safety trend analysis method based on improved Pearson correlation coefficient method is adopted. The system can be used to guide the balance scheduling of the power and water quantity,and provide technical reference for the power and water quantity balance management system in fossil-fuel power station.
Keywords:balance monitoring;informatization management;fossil-fuel power station;system design;improved Pearson correlation coefficient method
