确定热电联产中热、电分摊比的折合—法

Determining Cost Allocation with Reduced Exergy- Exergy Method

在热电联产中，热电分摊比的合理制定是直接关系到热电厂和热用户双方利益的一个重要的问题。根据睵在供热过程中起到的作用，引入折合皔的概念，考虑热电联产机组供热能量中的可用能占机组总可用能的比例，建立折合皔—皔法热电分摊比分析模型，并对几种典型机组的实际运行工况进行了计算。本文提出折合皔—皔法克服了其他方法存在的缺陷，物理意义明确，简单适用。

It is very important to establish reasonable cost allocation for heating and electricity in combined heat and power(CHP),owing to relating to their benefits for cogeneration plant and heating consumer.According to anery action in heat supply process in CHP,reduced exergy-exergy analytical model for cost allocation in CHP system is formulated through introducing the conception of reduced exergy and considering ratio of acting energy to general energy.Some practical conditions for typical units are computed and compared with different methods.Cost allocation adopting with reduced exergy-exergy method is more rationable and convenient and practical than existing methods with reference to the physical meaning of available anergy and calculations.
