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.
