Based on the real-time supervisory and management system in regional power grid company

as well as plant-level supervisory information system(SIS) in thermal power plants

a benchmarking information management system for combined real-time energy-saving in regional power grid company and power plants has been developed.Through establishment of production index system(range pole) in power plants and staged techno-economic indices

the on-line benchmarking management of real-time data has been realized

and the model of real-time energy consumption analysis and the model of condition-based equipment repair of units being constructed

on this basis.By using the results of benchmarking analysis

the energy consumption situation and transform efficiency in the production process have been quantified

being able to guide the operation optimization of units

reducing cost in production

and enhancing the energy effectiveness in power plants.
