摘要

本文针对某电厂百万机组基建期间核算购网电费所涉及的功率因数调整电费比例异常问题

为客观反映电厂外购电费

节约购电成本;通过对电厂调试期间机组启停的追朔

发现调整电费比例严重偏大

是由于计算功率因数时将发电机并网运行不应考虑的因机组进相、低励限制等试验

从系统吸收的无功电量也一并计算在内。因此重新核算

无功考核比例回归合理。

Abstract

As for abnormal power factor adjustment charging ratio involved in calculating the purchased network electric charge of 1 000 MW units at certain power plant during the construction peiod and for objectively reflecting purchasing electric charge of the power plant and save the purchasing cost

it is found through reviewing switch on and off of the unit during commissioning period in the power plant that the adjustment electric charge ratio is too big due to inlet phase and low excitation limit test of the unit as well as calculation of reactive power electricity absorbed from system which shall not be considered during operation of the generator in the network when calculating power factor.Therefore

recalculation is necessary so to keep reactive power assessment proportion reasonable.
