某钢铁企业产电和购电采用折标煤系数的研究

钢铁企业电力主要来源于两个部分:自产电和外购电，如何合理搭配它们之间的比例显得尤为重要.开展科学合理的电力生产和分析，对于电力生产调度、减少企业的经济成本是非常重要的工作.运用电力折算标准煤等价系数对某钢铁联合企业的电力进行分析，推导出计算的通用公式，并通过实例数据说明该钢铁企业外购电比例为295%最经济，与企业实际情况相符，验证了公式的准确性.

Research of Self generating Electricity and Outsourcing Electricity by Standard Coal Coefficient in an Iron & Steel Factory

Electricity in an iron & steel factory mainly comes from two parts: one is self generating electricity， and the other is outsourcing electricity.How to allocate reasonably the ratio between them is particularly important. Carrying out scientific and rational power production and analysis for production scheduling， reducing economic costs are very important work. In this paper， the standard coal equivalent coefficient was used to analyze power and the calculating formula was deduced. The data from the factory was used and showed that the outsourcing electricity of 295% is the most economic. The accuracy of the formula is verified.
