Calculating power tariff
Publish: 2021-04-20 18:39:16
1. It's troublesome for you to calculate in several steps, and you need to use your force adjustment coefficient
1. Actual power factor = total active energy / sqrt (total reactive energy square + total active energy Square)
2. Through the actual power factor and force regulation coefficient standard, look up the table to get the adjustment proportion, which can be found in the network force regulation comparison table
3. Step 3: force regulation electricity charge = (basic electricity charge + electricity charge) × Adjustment ratio
you also need to provide the power adjustment coefficient and electricity tariff (customer price)
1. Actual power factor = total active energy / sqrt (total reactive energy square + total active energy Square)
2. Through the actual power factor and force regulation coefficient standard, look up the table to get the adjustment proportion, which can be found in the network force regulation comparison table
3. Step 3: force regulation electricity charge = (basic electricity charge + electricity charge) × Adjustment ratio
you also need to provide the power adjustment coefficient and electricity tariff (customer price)
2. Hello, you can't buy a hoe for the mobile version of legend of hot blood. mining method, click the calendar in the upper right corner of the mobile & gt; Daily activities & gt; Slide up the screen to select mine, and click go. It will automatically find the way to find the foreman, transmit it to the mining map, enter the mining map, and a hoe sign will appear in the lower right corner of the mobile phone. When the character is close to the wall, click the sign to automatically mine. It can only dig for half an hour every day, and it will be automatically transmitted to the foreman after half an hour. The mining map is only transmitted to the foreman.
3. The first simple calculation method is
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)
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

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.

You can find it on the Internet
power factor = active power consumption / √ (square of active power consumption + square of inactive power consumption)
4. 1. First of all, according to the "power factor adjustment tariff method" and your actual electricity situation, determine your power factor assessment standard
2. Secondly, calculate a ratio according to the total reactive power / total active power of your actual electricity consumption ring the billing period, that is ( reactive power + variable loss reactive power) / ( active power + variable loss active power)
3. Then check the calculation method and check table of transformer loss and power factor in Guangdong Province, select the row in the table according to the upper and lower limits of the ratio, and select the column in the table according to the assessment standard in step 1 to find out the adjustment rate
4. Finally, use this adjustment rate * (the sum of basic electricity charge and electricity charge) to adjust your electricity charge.
2. Secondly, calculate a ratio according to the total reactive power / total active power of your actual electricity consumption ring the billing period, that is ( reactive power + variable loss reactive power) / ( active power + variable loss active power)
3. Then check the calculation method and check table of transformer loss and power factor in Guangdong Province, select the row in the table according to the upper and lower limits of the ratio, and select the column in the table according to the assessment standard in step 1 to find out the adjustment rate
4. Finally, use this adjustment rate * (the sum of basic electricity charge and electricity charge) to adjust your electricity charge.
5. I calculated according to the data you gave, and the measurement at your place should be at the high pressure side
in case of low-pressure side metering, the calculation is much more complicated
power factor = active power consumption / √ (the square of active power consumption + the square of non active power consumption)
0.92 = 42919 / √ (42919 * 42919 + 18000 * 18000)
then according to the power rate (that is, power factor), check the power rate adjustment method to know the power rate charge
if it reaches 0.92, there should be a reward, because most electricity users will not be punished if their power ratio reaches 0.90, and if your power ratio exceeds 0.90, there should be a reward for electricity charges
the negative power rate electricity charge is displayed on the electricity bill
the national power supply and consumption rules stipulate that the power supply department will charge a part of the electricity fee for the users whose power factor fails to meet the above requirements; If the power factor exceeds the above-mentioned requirements, the power supply department will rece part of the electricity charge - reward electricity charge. The specific implementation shall be in accordance with the measures for power factor adjustment of electricity charges
high voltage metering users: power rate tariff = (kilowatt hour tariff + basic tariff) × Penalty ratio
reward electricity charge = (electricity charge per kilowatt hour + basic electricity charge) × Reward proportion
low voltage metering users: power rate electricity charge = electricity charge per kilowatt hour × Penalty ratio
reward electricity charge = electricity charge per kilowatt hour × Reward proportion
the electricity charge of electric degree refers to the power charge, excluding the lighting charge, and the lighting does not participate in the power rate assessment. When the capacity of transformer exceeds 315KVA, users of high voltage metering will charge basic electricity fee. The basic tariff is charged according to the capacity of the transformer. It can be seen that the regulation of power rate and electricity charge is the promotion means for the power management department to urge the power users to do a good job in reactive power compensation, which has great economic benefits for both the power supply and the power consumption
