How to calculate the electricity consumption of residential areas?

The construction area is less than 120 square meters, each household is calculated according to 8kw, 120-150 square meters, each household is calculated according to 12kw, 150-200 square meters, each household is calculated according to 16kw, and more than 200 square meters is calculated according to 80w square meters. Hand hope to adopt.

It is estimated by adding the average kW of electricity consumption per household.

Residential 6-10kw calculation, commercial 10-12kw calculation.

The calculation of transformer capacity selection is based on the conventional calculation method;

It is the total design capacity of residential users in the community, which is the sum of the capacity of one household and one household, and because the residential electricity is single-phase, it is necessary to convert this number into three-phase four-wire electricity, then, the relationship between the phase current and the line current is the problem of the root number 3, that is, the sum of the single-phase power is divided by the power of the three-phase four-line, for example, there is a community now, 200 houses, each household 6-8kw electricity consumption, the sum of one household is 1400 808kw, This number is the maximum power of all electrical appliances in the community when used at the same time, then, when actually used, this situation will not happen, then, there is a called simultaneous electricity consumption rate, generally choose 70-80%, which is determined according to the user structure characteristics of the community.

However, according to the economic operating value of the transformer is 75%, then, we can offset these two values, according to the power to find the capacity of the transformer, then, the capacity of this transformer is the total total power of 1400, according to the situation of residential electricity, the power factor is now, the apparent power sp = p = 808 951kva.

How can it be calculated, first divide the total 1400 power into three lines of power, that is, single-phase power, 1400 3 = 467kw, and then, convert this single-phase electricity into three-phase electricity, 467 808kw, and then divide it by the power factor 951kva.

According to the standard capacity of this data set transformer, it is recommended to choose two transformers, with a total capacity of 945kva, one 630kva, the other 315kva, which can also be put into use in batches during the actual construction process, if you take into account the future development, you can also choose two 500kva transformers, or directly choose one 1000kva.

How to calculate the voltage of 10kV, the capacity of 1kVA transformer, and the rated input and output current;

We know that the power kva of the transformer is the apparent power, and there is no need to calculate the power factor when calculating the three-phase AC current, therefore, sp = 3 u i Then, i low = sp 3 That is to say, the rated output current of the transformer capacity of 1kva is selected according to the effective rate of the transformer and the energy consumption ratio. The rated current at full load of high-voltage 10kV input to the transformer is approximately; i High = SP 3 10 = 1 That is to say, the high-voltage rated input current of the transformer with a capacity of 1kVA is.

It is to add up the monthly electricity consumption of each household together is the annual electricity consumption of the community, if the average annual electricity consumption of the community is calculated, it will take at least a few years of community electricity consumption.

According to the current regulations and property management measures, China's current residential public electricity load mainly includes public lighting, elevator electricity, domestic water electricity, underground garage electricity, etc. The total capacity of the common part lighting can be calculated by w m2 10w m2, coefficient method. The coefficient is usually selected according to the specification, and the coefficient is taken when the area is less than 500m2; 500m2 3 000m2; When it is greater than 3 000 m2.

The electricity consumption of a single elevator is the sum of the rated power of its own motor and other auxiliary electrical. If the elevator is powered by DC, it is necessary to pay attention to the calculation of the rated power of the AC motor using the dragging DC generator. If it is powered by multiple elevators, the total capacity should be included in the working factor.

The electricity consumption of domestic water supply is calculated, and the sum of the rated power of all feed pumps is calculated when the water supply is centralized. When the water supply is dispersed, the working factor is added to calculate the total capacity. Coefficient selection principle:

1 5 pumps take 1; More than 5 pumps. The electricity consumption of the underground garage is summed according to the total electricity consumption, and the total electricity consumption is usually 20w m2 and 30 w m2, and the coefficient is taken. Commerce.

Hello dear. See how it helps you? My dear.

Please give it a thumbs up! Kiss.

Questions. No result.

I need a data.

How much electricity is used by 3,000 households.

Wait a minute.

Good. A community of 3,000 people needs 4,500kw

Can you see how it helps you? Kiss.

Please give it a thumbs up! Kiss.

Questions. 3,000 households.

Yes dear. Questions.

Not 3000h

Ok thanks.

According to the calculation of 3,000 households in a community, the annual electricity consumption is 78,840 kWh. Electricity consumption in the sense of convenience is a huge number every year.

Ok thanks.

Okay pro. See how it helps you? Kiss.

The calculation of annual electricity consumption mainly depends on what you use the equipment, first of all, you must calculate the total power consumption of your equipment, and then multiply it by the electricity usage coefficient, and then multiply it by the number of days of electricity consumption, which can be calculated.

You can connect two wattmeters on the main transmission line to test the electricity consumption at different times of the year in different seasons and then estimate!

What is the use of all the electricity and heat given to the conditions.

You have to count this yourself.

According to the provisions of the Notice of the Ministry of Water Resources and Electric Power on the Issuance of Electricity and Heat ((75) Hydropower Cai Zi No. 67), the non-industrial electricity price for elevators and pumps in residential areas shall be implemented.

No, the public electricity is not calculated according to the tiered method, but according to the standard of the residential metered electricity price. The electricity price for residential metered users will be uniformly increased by yuan kilowatt hours this time.

The formula for calculating the basic electricity tariff, how to calculate the electricity tariff after the implementation of the residential tiered electricity tariff.

If it is used to calculate the electricity load, you can check the "Residential Electricity Load Demand Factor Selection Table", 04DX101-1, page 24.

Add all the electrical loads together* or run at the same time, and this is the electricity load you calculated. This is a rough algorithm, and there are many parameters to calculate the electrical load during the design.
