As one or more embodiments, the settled electricity consumer electricity fees include daily clearing electricity fees and monthly accounting electricity fees; the daily clearing only calculates daily electric quantity, the electricity purchasing settlement application is responsible for calculating daily settlement electric quantity of the power generation enterprises, and the result is pushed to the transaction center for segmentation. The monthly settlement needs to calculate electric quantity electric charges of the non-marketization and the marketization, wherein the calculation of the electric quantity electric charges of the marketization part needs to push the settlement electric quantity of the marketization metering point to the transaction center for segmentation, the transaction center pushes the segmentation electric quantity to the electricity purchasing settlement application after segmentation, and the electricity purchasing settlement application calculates the marketization part electric quantity electric charges of the power generation enterprises according to the segmentation electric quantity result.
In the metering mode of power generation enterprises, it is common and common to use main sub-meter metering (total settlement electric quantity=main meter reading electric quantity-sub-meter electric quantity sum); if the time-sharing meter is adopted for metering, then calculating time-sharing electric quantity according to the proportion of each time period (the time-sharing electric quantity=the total settlement electric quantity is the proportion of the corresponding time period); the final peak Gu Pingzhi sum is not equal to the total and is leveled with the usual period as the adjustment period.
Several common metering and configuration modes are described below:
(1) The total network electricity quantity is apportioned according to the meter reading electricity quantity proportion, a schematic diagram is shown in fig. 3, a plurality of units are arranged below a total gateway port, each unit is provided with a meter, and the total gateway port electricity quantity is calculated by the total network electricity quantity = the sum of the meter reading electricity quantity of the units/the meter reading electricity quantity of the units; the calculation formula is used for obtaining:
the network-surfing electric quantity of the unit A is = [ 20/(20+40+50) ]. 100
The network-surfing electric quantity of the unit B is = [ 40/(20+40+50) ]. 100
The network-surfing electric quantity of the unit C is = [ 50/(20+40+50) ]. 100
(2) The total network electricity quantity is apportioned according to the ratio of the meter reading, the schematic diagram is shown in figure 4, a plurality of units are arranged under the total gateway port, and the calculated electricity quantity of each unit on the network is equal to the ratio of the total gateway port electricity quantity; according to the calculation formula, the following can be obtained:
unit a network access electricity=100×20%
Set B network power=100×30%
Unit C network power=100×50%
(3) The line loss is allocated according to the line loss allocation coefficient of the machine set, the schematic diagram is shown in figure 5, three machine sets are arranged below a main upper gateway port, the three machine sets are provided with own tables, the A, B, C machine sets allocate the line loss according to the line loss allocation proportion of 60%, 40% and 80%, namely, the A machine set participates in the line loss allocation calculation with 60% of meter reading electric quantity, the B machine set participates in the line loss allocation calculation with 40% of meter reading electric quantity, and the C machine set participates in the line loss allocation calculation with 80% of meter reading electric quantity; total line loss = sum of sub-meter network power-main meter total network power; the sum of the unit line loss allocation coefficient electric quantity is the sum of the current unit meter reading electric quantity multiplied by the current power station line loss allocation coefficient; according to the formula, it can be obtained that:
bus loss=50+60+10-100=10
Unit a apportions line loss amount= [ (50 x 60%)/p division ]. Total line loss = 4.84
Unit B allocates line loss power= [ (60 x 40%)/p division ]. Total line loss = 3.87
Unit c allocates line loss power= [ (10 x 80%)/p division ]. Total line loss = 1.29
If the power plant participates in spot goods transaction, the settlement electric quantity is required to be shared to 96 points in daily clearing, contract electric quantity, daily front electric quantity and real-time electric quantity of each time period of 96 time periods are calculated, deviation electric quantity is calculated, daily clearing contract electric charge, daily front electric charge, daily clearing real-time electric charge and daily clearing deviation electric charge are calculated according to various electric quantities, the deviation of the monthly settlement electric quantity and daily clearing settlement electric quantity sum is calculated according to the monthly market electric quantity calculation result in monthly settlement, the obtained deviation is used as leveling electric quantity, the leveling electric charge is calculated according to the leveling electric charge, the sum of the daily clearing electric charge and the leveling electric charge are added to calculate market transaction part electric charge of the power plant, non-market part electric charge is overlapped, and the total electric charge of the power generation month is obtained in a summarizing mode.
