| In order to carry out the 11thFive-Year layout outline of national economy and society development and realize the restriction aim of decreasing energy using for 20% per GDP, the National Development and Reform Commission constitutes implementing opinions of 10 big important energy saving project in 11th Five-Year Plan.This article studies a kind of new energy saving mechanism based on the market——Contract Energy Management (CEM) application in motor system energy saving in our country. Through studying EMC by the way of contract energy management to carry on frequency conversion and velocity modulation rebuilding in SINOPEC XX Petrochemical's pump and air blower, has unfolded EMC's main operation flow when provides the energy service, and analyze the cost benefit of energy conservation project. In order to better use EMC's important function in motor system energy saving service, this article analyzes the main obstacle which EMC come up against in motor system energy service process and offers corresponding promoting countermeasures and measures. |
