基于煤耗特性的火电厂动态成本模型研究

The Research on Dynamic Modeling of Cost in Power Plant

在"厂网分开,竞价上网"的电力体制下,电能成本的分析对发电企业的生产运营已显得尤为重要。重点研究在"煤电联动"机制还没有完全实现、机组负荷不稳定的条件下,电能成本如何变化。在分析了电能成本构成的基础上,运用定性、定量相结合的方法给出了机组成本、利润函数模型,并以实际数据分析了机组负荷率、煤耗率及燃煤价格对成本利润的影响。最后以某300MW电厂为例,给出了机组实时成本利润曲线。对火电企业的运营有一定指导意义。

Since the implementation of ＂ factory nets separate, bidding for access＂ on the power system reform, power generation producers become competition entities, power generation cost analysis for production and operation of enterprises has been very important. In today＇s power market conditions ＂coal linkage＂ mechanism has not been fully realized, in the case of coal prices uncertain,how to control the production cost of power generation in order to gain profit is a critical issue. This paper analyzes the influence of cost, profit thermal power, to construct the cost-profit function model, and the calculation of main energy dissipation index the influence degree on the cost and profit. To the operation of thermal power enterprise has certain directive significance.
