浅析海外电力总承包项目的厂用电量计算方法

Analysis of Calculation Method of Auxiliary Power Consumption for Oversea Power Plant Project

电厂厂用电量,既关联机组净出力又关联机组净效率,是衡量火力发电机组的重要技术经济指标。特别对海外电力总承包工程而言,在工程投标与建成移交阶段,厂用电量及其关联指标是考量电力总承包工程的重要性能指标。为此,通过国际惯例来诠释海外电力总承包项目厂用电量的意义、常见罚则,并给出适用的估算厂用电量的方法及投标阶段常用应对措施。研究成果将对越来越多走出国门的中国电力总承包企业有很好的指导作用。

Auxiliary power consumption is related to the unit net output and the unit net efficiency, which is an important technical and economical index of fossil fuel power plants. Especially for oversea turnkey project, auxiliary power consumption is an key per- formance index to be judged during the bidding stage and tested during the acceptance certificate stage. International common practice is used to illustrate the meaning and the common penalty about the auxiliary power consumption. Applicable calculation method of the auxiliary power consumption is given and also the measurement during the bidding stage. The conclusion of this paper will give an guidance for more and more Chinese enterprises which go abroad.
