大型热电机组供热、发电厂用电率计算方法探讨

本文对现行"厂规"中热电厂供热厂用电率、发电厂厂用电率的计算方法进行了探讨,认为现行"厂规"的计算方法不适用于有再热系统的大型热电两用机组的计算,提出了在新版"厂规"发布之前,建议采用的计算公式。同时根据热电两用机组对外供热量越大,发电功率越小的特点,提出了计算采暖季发电厂用电率时应采用采暖季平均抽汽工况的发电功率计算。并提出了对现行"厂规"进行修订有关建议。

Discussion on Heating and Qenerate Electricity Power Consumption Rate Calculation Method of Large Capacity Thermoelectric Unit

This paper first discussed the calculation method of heating and generating power consumption rate of thermal power plant in existent "code about power server station".Found it was not applicable to large capacity thermoelectric unit with reheat system.Then put forward a reasonable calculation formula propositionally before new "code about power server station" issued.And according to characteristics of more heating and less generating in large capacity thermoelectric unit,the author put forward that average generated power of heating season should be used when power consumption rate of heating season is calculated.Finally,put forward the relevant suggestion for emending existent "code about power server station".
