Description

Jie Feishi energy-saving management system and method thereof
Technical field
The invention relates to a kind of Jie Feishi energy-saving management system and method thereof, be meant a kind of System and method for that is used in administration of energy conservation especially.
Background technology
Building energy management system and method and to be difficult to save the electricity charge be the fundamental purpose function in the past, generally only focus on and collect electricity consumption data and electric power monitoring and management, and electricity consumption data aggregation result only can there is no direct relation with saving the electricity charge as the reference frame of energy management; Must understand electricity charge account form if desire to reach the purpose of saving the electricity charge, and set suitable frequent contract capacity with Utilities Electric Co., list only collects electric power data by energy management system or electric power monitoring can't directly reach the purpose of saving the electricity charge.
This shows that the above-mentioned mode of commonly using still has many disappearances, real non-good design, and demand urgently being improved.
Summary of the invention
Fundamental purpose of the present invention is to be to provide a kind of Jie Feishi energy-saving management system and method thereof, is to analyze passing annual electricity consumption historical data for utilizing, and reaches direct reduction basic charge as per installed capacity and avoids an about additional cost of excess of export to obtain best contract capacity.
