3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Generation standard coal consumption thestandardcoalconsumptionperunitproductionofpowergeneration Generators each issue of coal per unit of energy consumed by the average, including the production of the amount of energy consumed directly, as well as to the production-sharing The amount of energy the amount of energy and energy losses in the system and other products of auxiliary production systems and ancillary facilities for the production system of indirect consumption. 3.2 Power plant (field) power consumption rate powerconsumptionrateofpowergeneration During the reporting period generator sets for power generation production plant (field) accounts for a percentage of electricity generation capacity. 3.3 Power supply standard coal consumption thestandardcoalconsumptionperunitproductionofpowersupply Generators to provide power supply unit of the average amount of coal consumed to the grid. Power supply standard coal consumption according to equation (1). bg = bf1-Lfcy (1) Where. bg --- power supply standard coal consumption, in units of grams of standard coal per kWh [gce/(kW · h)]; bf --- generation standard coal consumption, in units of grams of standard coal per kWh [gce/(kW · h)]; Lfcy --- power plant power consumption rate,%. 3.4 Integrated grid line loss rate theintegratedlinelossrateofthepowergrid Grid enterprises within the network coverage, the rate of energy loss in the power transmission network in all sectors generated. Calculation conditions Press DL/T686 Execution, integrated power grid line loss rate is calculated according to the formula (2). Integrated grid line loss rate = [(power supply - electricity sales)/power supply] × 100% (2) ......
