Operation effect evaluation method of heat supply stations based on extension theory

Based on a large number of operation investigation data of heat supply stations and the index system of VDI 3807 in Germany and the relevant heating standards in China, drafts the evaluation index and operation effect grades of heat supply stations. Establishes the evaluation model and method of heat supply stations operation effect based on extension theory. Evaluates the operation effect of a heat supply stations in Beijing by single index and comprehensive operation effect. Combined with the evaluation results, points out the operation problems of the heat supply stations and provides some suggestions for improvement.
