An equipment energy efficiency evaluation method for industrial and commercial use

With electrical energy conservation and emissions reduction promotes in China, the research on electrical energy efficiency evaluation has become one of the hot topics in the studies on power system. Meanwhile, with customers´ requirement on accurate assessment increases, it´s a trend to change from energy measurement to efficiency measurement of equipment in industrial and commercial scenes. An equipment energy efficiency on-line monitoring method was introduced for industrial and commercial use and an equipment energy efficiency evaluation model with probability was described in detail. The simulation on three-phase asynchronous motor with MATLAB indicated the feasibility of the evaluating model and method, which could effectively promote the appliance of energy efficiency on-line monitoring and reduce economic investment for monitoring.
