本文将建立在热力学第二定律基础上的#［1316］分析方法与热经济学方法运用于能量系统的故障诊断。通过与常规热力学方法的定量比较，证明了#［1316］分析方法与热经济学方法对系统中发生的故障具有更高的敏感度，并建立了进行能量系统故障诊断的#［1316］分析模型与热经济学分析模型，并以某200 MW火电机组为例，分别采用这两种方法对机组在某一况时的故障情况进行了诊断，并对结果进行了分析比较。
The exergy analysis method and the thermoeconomicsanalysis method are used for faults diagnosis of an energy system.By comparing the two methods with the traditional thermodynamicsmethods，it is proved that they have higher sensitivitythan the traditional methods. The mathematical modelsare built up to find the malfunctions in an energysystem. By taking a 200MW power generating unit asan example, some malfunctions are diagnosed based onthe exergy analysis mathod and the thermoeconomicsmethod respectively. The results are compared andanalyzed in detail.
