摘要:
变电站在输送电能的过程中会产生大量能耗,变电站能效评估是进行电力系统能效提升的基础。首先,分析了变电站的能效及其影响因素;然后,从电气设备性能、系统运行状态、建筑结构性能和运行环境因素4个角度构建变电站能效评估指标体系,并给出指标计算模型;采用层次分析法(AHP)求取各能效指标权重,并利用灰色关联分析法对变电站进行能效综合评估;对实际变电站数据进行仿真分析,结果表明基于灰色AHP的变电站能效评估指标及模型能够有效反映变电站的能效水平。

Abstract:
The energy efficiency evaluation of substation is the basis for improving the energy efficiency of power system due to its great energy consumption during the power transmission. The substation energy efficiency and its influencing factors are analyzed and an energy efficiency evaluation index system for substation is then established in four aspects: electrical equipments, power system operation, building structure and operational environment, for which the corresponding calculation models are presented. AHP(Analytic Hierarchy Process) is applied to calculate the weight for each index and GRA(Grey Relation Analysis) is used to comprehensively evaluate the substation energy efficiency. The results of a simulative analysis based on the actual substation data show that, the proposed indexes and models for the substation energy efficiency evaluation based on the grey AHP can effectively reflect the level of substation energy efficiency.
Key words:  electric substations  energy efficiency evaluation  index system  calculation model  comprehensive evaluation  influencing factors  grey relation analysis  analytic hierarchy process
