摘要
为实现整个能量系统在偏离最佳经济工况时的经济性分析和诊断,及对于系统中某单元或设备的设计优化和经济运行,以热经济学理论与方法建立边际火用成本能耗分析模型,按照产品形成过程去追踪燃料消耗量,并便于计算庞大系统复杂参数变化的能损分布问题,为机组节能潜力的诊断提供决策依据。通过计算机编程对200MW机组进行了求解,其结果表明:机组参数偏离设计工况时,不同参数引起的能耗增加不同,且符合自然累加原则,并进行了系统仿真模拟,验证了该模型的可靠性。
In order to carry out an economic analysis and diagnosis as well as for a design optimization and economic operation of a component or device in a system, a model for analyzing marginal exergy cost of energy consumption is established by using the thermoeconomic theory and method. The features of the model established are that it is very convenient to calculate the exergy dissipation allocation for huge energy system with complex variation of its parameters. This model provides some bases for finding the energy-saving potential and diagnosis for decision. By using a computer program, a solution for 200 MW unit has been proceeded. The results show that for different parameter, the deviation of energy consumption is different, and it is coincided with the natural laws. The model is used in unit emulator, and its high reliability is obtained.
