Thermoeconomic Method for the Performance Diagnosis of a 200MW Power Plant

在热经济学结构理论的基础上 ,讨论了热力系统运行性能诊断的热经济学方法 ,以 2 0 0MW机组热力系统的计算模型为例 ,阐述了各部件及产品关系 ,建立了系统的热经济学生产模型 ,并对故障诊断的方法、故障引起的系统资源消耗增量进行了理论分析和实际计算 ,提出了具有较高灵敏度的故障判别指标 ,以及反映故障影响的量化指标 。

On the basis of a thermoeconomics structure theory discussed is a thermoeconomic method for the operation performance diagnosis of a thermodynamic system. With the thermodynamic system calculation model of a 200 MW power plant serving as an example the fuel/product relation of constituent elements is expounded and the thermoeconomics production model is set up. After a theoretical analysis and practical calculation of the increase in system resource consumption caused by a failure, indexes of relatively high sensibility for failure discrimination are proposed. A quantized index for reflecting the impact of failures is also given while analytical computations are performed for some specific cases.
