在电力市场环境下,机组的稳定性能已不再单纯是技术问题,而直接关系到发电企业的盈利和竞争能力,要求可靠性指标能体现机组的技术性和企业的盈利性。在对现有可靠性指标分析的基础上,提出一套新的评价指标体系——商业可用性指标体系,并用一个算例对新的评价指标体系应用拉开档次法作了综合评价。 In the electricity market environment, the stability of the unit is no longer a purely technical issue, but is directly related to the profitability and competitiveness of the power generation enterprises. The reliability index is required to reflect the technicality of the unit and the profitability of the enterprise. Based on the analysis of the existing reliability index, a new set of evaluation index system - Commercial Usability Index System is proposed, and a new evaluation index system is applied to evaluate the new evaluation index system.
