摘　　要：新能源发电快速发展带来发电装机结构不断发生变化,依据传统方法计算的分类型和全口径发电设备利用小时不能像以往那样直观反映发电设备利用率水平。提出了发电设备"基准利用小时"概念,定义了发电设备利用率指数为利用小时占基准利用小时的百分比,给出了设计利用小时和可比利用小时2组标准取值,在此基础上提出了利用率指数计算模型。通过不同地区、不同企业的利用小时与利用率指数的比较分析,验证了利用率指数能够在充分考虑发电类型容量结构的前提下,真实反映发电设备利用率水平,可为电力规划分析、企业项目管理提供新的更加科学合理的指标体系。The rapid development of new energy has brought about constant change of electricity generation structure,leading to the inability of the traditional availability hour to directly reflect the utilization level of power generating equipment.A concept of"benchmark availability hour"is thus proposed,and the availability index is defined as the ratio of availability hour to the benchmark availability hour.The reference values for the design availability hour and comparability availability hour are given respectively in the paper,and then an availability index calculation model is proposed.Through comparison of the generating equipment availability hours and availability indexes in different regions and different companies,it is proved that the availability index can factually reflect the utilization level of power generating equipment under the circumstance of generation structure being taken into consideration adequately.This new index and method can be used for power planning and project management.
