分析了火电机组厂用电率测试结果修正的原因,介绍了磨煤机、风机和给水泵厂用电率测试结果的修正计算方法.以某300 MW空冷机组为例进行了厂用电率测试结果的修正计算,得到该机组实测辅机总耗电功率为24751 kW,厂用电率为8．28％,修正后的总耗电功率为24513 kW,厂用电率为8．17％.
分析瞭火電機組廠用電率測試結果脩正的原因,介紹瞭磨煤機、風機和給水泵廠用電率測試結果的脩正計算方法.以某300 MW空冷機組為例進行瞭廠用電率測試結果的脩正計算,得到該機組實測輔機總耗電功率為24751 kW,廠用電率為8．28％,脩正後的總耗電功率為24513 kW,廠用電率為8．17％.

The reasons why we need to carry out correction for measured auxiliary power consumption rate were analyzed,and the correction methods for coal mills,fans and pumps were elaborated.Moreover,a 300 MW air cooling unit was taken as the example to conduct correct calculation for the measured auxiliary power consumption rate.The results show that,the actual measured total electricity consumption and aux-iliary power consumption rate of this unit were 24 751 kW and 8.28%,respectively.After correction,they reduced to 24 513 kW and 8.17%.
