How to calculate the electricity charge
first, the receivable electricity charge = electricity charge + basic electricity charge + interest rate adjusted electricity charge
electricity charge = Active Power * electricity price = 2650 * 0.5344 = 1416.16 yuan
basic electricity charge = transformer capacity * basic electricity price = 400 * 26 = 10400 yuan
calculation method of interest rate adjusted electricity charge:
first, determine the interest rate standard< The power factor standard is 0.90, which is applicable to high-voltage power supply instrial users above 160 KVA (including community instrial users), high-voltage power supply power users with load voltage adjustment device and high-voltage power supply drainage and irrigation stations above 3200 kVA
the power factor standard is 0.85, which is applicable to other instrial users (including Shei instrial users) with 100 KVA (kw) and above, non instrial users with 100 KVA (kw) and above, and power drainage and irrigation stations with 100 KVA (kw) and above
the power factor standard is 0.80, which is suitable for agricultural users and wholesale users with 100 KVA (kw) or above, but for wholesale users whose large instrial users are not directly managed by the power instry, the power factor standard should be 0.85
your power factor standard should be 0.9
then calculate the real interest rate of this month, and your power factor is 0.52. Compare your actual power rate with the power rate meter in Tuli issued by the elder brother upstairs. If the power factor is more than 0.9 under the standard of 0.9, every 0.9x indicates the percentage of additional electricity charge. Then multiply the sum of electricity charge and basic electricity charge by this percentage to get the interest rate adjustment electricity charge. On the contrary, if it is lower than 0.9, every 0.9x indicates the percentage of electricity charge rection, and the calculation method is the same as above
in the end, the total electricity charge you should pay in the current month is the electricity charge + basic electricity charge + interest rate adjustment electricity charge. The generation tariff you mentioned is included in 0.5344/kwh, so there is no need to calculate it separately. I don't have the power ratio adjustment comparison table. You can find it on the Internet
power factor = active power consumption / √ (square of active power consumption + square of inactive power consumption)
transformer type: such as S7, S9, S11...
transformer capacity: such as 100kVA, 125kva, 315KVA...

power factor adjustment table
total active power of the current month
total reactive power of the current month
with the above conditions, it can be calculated manually, Now it's basically computer generated by the power supply company
the specific calculation method is as follows:
1. Divide the total reactive power of this month by the total active power, and calculate the power ratio
2. According to the power rate, check the transformer loss quick calculation table. Here, find out the value of copper loss and iron loss according to the transformer model, capacity and electricity of this month
3. Use the active power and reactive power of this month, plus copper loss and iron loss respectively
4. Divide the total reactive power by the total active power to calculate the actual power rate
5. According to the actual power rate, check the power factor adjustment table to calculate the percentage value of the power adjustment fee
6. Multiply the "percentage value" found by the catalog tariff, the positive number is the tariff to be increased, and the negative number is the tariff to be decreased
hope to help you.
The basic tariff is calculated according to the customer's transformer capacity or maximum demand and the basic tariff approved by the state
power regulation fee generally refers to power regulation fee, which refers to the relevant electricity fee charged by the power supply company according to the average power factor calculated by the active and reactive power used by the customer in a period of time (such as a month or a year)
there are two ways to calculate and collect the basic electricity charge, which can be calculated and collected according to the transformer (rated) capacity or the maximum demand. If the customer chooses to charge the basic electricity charge according to the maximum demand or transformer capacity, it shall be specified in the power supply and consumption contract and shall not be changed within the validity period of the contract
the charging quantity of the power adjustment charge on the electricity bill is the percentage of the total electricity charge (i.e. "adjustment rate") according to the power factor. This "adjustment rate" is different according to the corresponding power factor. If the power factor is high, the charge rate will be low, and if the power factor is low, the charge rate will be high. This rate may vary slightly from place to place. Please refer to the local electricity policy
extended data:
basic electricity charge standard of transformer:
1. According to capacity: the basic electricity charge standard for proction of synthetic ammonia, electric furnace calcium magnesium phosphate fertilizer and small and medium chemical fertilizer is 14 yuan / KVA / month; The basic electricity charge standard of other large instrial customers is 18 yuan / KVA / month
2. According to demand: the basic electricity charge standard for the proction of synthetic ammonia, electric furnace calcium magnesium phosphate fertilizer and medium and small chemical fertilizers is 21 yuan / kW / month; The basic electricity charge standard for other large instrial customers is 27 yuan / kW / month
Suppose that the active power is a, the reactive power is B, and the power factor is cos φ， Then
monthly average power factor: cos φ= A / root sign (square of a + square of B)
the power factor standard requires 0.9
power factor reward and penalty regulations: when the power factor is lower than the standard by 0.01, the penalty will be increased by 0.5% from the total electricity charge, which will be increased to 1% for each level lower than 0.7 and 2% for each level lower than 0.65; For every 0.01 higher than the standard, 0.15% of the total electricity charge will be awarded, and so on, the top will be 0.75%

Electricity charge: basic electricity charge, catalog electricity charge is the electricity charge copied on the meter,
basic electricity charge: capacity charge for transformer above 315KVA.
line loss: line loss
variable loss: transformer loss.
total electricity charge = basic electricity charge + catalog electricity charge + line loss + variable loss electricity
metering device should be installed at the property right demarcation point. The line loss and transformer loss generated at the load side of the demarcation point have been recorded in the metering device, and the power consumption = end code of this month (period) - last (period) at least = line code * Pt ratio * CT ratio = power consumption of the current month (period), unit: kW. H. The electricity consumption of the current month (period) multiplied by the unit electricity price is equal to the electricity charge
the line loss is rated. There is a power supply contract every year, which says that it is determined according to the capacity, whether it is a special line, and then the monthly electricity consumption multiplied by the fixed percentage is the line loss
the reactive line loss is calculated by multiplying the total reading of reactive power on the meter and the total reading of reactive power reverse by the multiplying factor. The total reactive power must be less than the total active power, otherwise the power factor is too low, and the power adjustment charge and additional charge will be charged
extended data:
the part of electricity charge calculated according to the actual electricity consumption. The cost of electricity consumption is to compensate the part of variable cost expenditure of power enterprises which changes with the change of power generation and supply. For small consumers such as residents, the electricity charge is the total electricity charge they should pay
for the users who implement the two-part tariff, the electricity tariff is only a part of the payable electricity tariff, and the basic electricity tariff is the total payable electricity tariff. The electricity charge is calculated based on the reading of the active energy meter in the charging energy metering device installed by the power enterprise at the user's place
since the meter count is a cumulative value, the difference between the final reading and the initial reading should be taken into account when calculating the power consumption within a specified period. When the current transformer and the voltage transformer are installed in the electric energy metering device, the transformation ratio of the current transformer and the voltage transformer should be multiplied respectively
the transformation ratio of current transformer (or voltage transformer) is the ratio of rated current (or voltage) of primary winding and secondary winding of current transformer (or voltage transformer)
if the charging energy metering device of high-voltage users is installed on the low-voltage side of its special transformer, it is called high supply and low quantity users when implementing the specified electricity price on the high-voltage side. For the electricity consumption of such users, the active power loss part of the copper iron loss of the special transformer for users should be included in the electricity consumption to calculate the electricity rate and electricity charge
total active power:
3240 + 880 = 4120 (KWH)
reactive power:
780 + 4330 = 5110 (KWH)
monthly average power factor:
cos φ＝ Active power / root (square of active power + square of reactive power) = 4120 / root (4120) × 4120＋5110 × 5110) ≈ 0.63
the standard requirement of power factor is 0.9, now it is only 0.63, lower than the standard: 0.9-0.63 = 0.27
power factor reward and penalty regulations: when the power factor is lower than the standard by 0.01, the total electricity charge will be fined by 0.5%, which will be increased from 0.7 to 1%, and from 0.65 to 2%; For every 0.01 higher than the standard, 0.15% of the total electricity charge will be awarded, and so on, the top will be 0.75%
according to the regulations, the penalty percentage of the total electricity charge is 19%
