Description
Technical Field
The present application relates to the technical field of electric energy meters, and in particular, to a method, an apparatus, a computer device, a storage medium, and a computer program product for calculating a demand of an electric energy meter.
Background
Along with the gradual vigorous demand of electric vehicles, when a plurality of electric vehicles are connected to a power grid for charging, the electric power department can bring about the great change of the load of the power line, and the electric power department needs to predict the load of the power grid and implement a peak clipping and valley filling method to ensure the voltage stability and the load balance of the power grid. The large industrial user load fluctuation value is large, the impact on the power grid is particularly great, and the current power department carries out two electricity prices for the power transformer with the capacity of more than 100 kilovolts ampere in industry, commerce and other users, wherein the two electricity prices consist of two parts of electricity prices, namely a basic electricity price and an electricity price. The basic electricity price is generally charged according to the capacity of the transformer, and the maximum monthly demand can be charged, namely the electricity price is the electricity fee actually used by the user. When the demand is used as a charging mode, the realization and calculation methods of the demand in the electric energy meter become as important as the electric energy metering.
The demand is a power measure, which refers to the average value of power in a prescribed demand period, and the maximum demand is the maximum value of demand recorded in a prescribed settlement period.
The existing demand calculation methods include the following:
1. Slip type. Each slip time T obtains a power value P i, i e { 1..once, n }, n >1, n is the number of slip, and when the first time the demand period t=n×t is reached, the demand calculation d= (P 1+...+Pn)/n is performed. The method can only achieve the purpose of measuring the needed quantity simply and roughly, and once the needed quantity is in a certain slip time, the needed quantity can not accurately reflect the load condition of a user in the period of the needed quantity because the user electric equipment is started or the equipment operates abnormally, and the power value just obtained at the moment is an instantaneous peak value of the equipment, and no energy is actually generated and the power grid can not be impacted, or the needed quantity can not accurately reflect the load condition of the user in the period of the needed quantity because the user electric equipment is shut down in the certain slip time, and the power value is very small or 0 after the power value is obtained.
2. For an improved method of the above slip, the average power is calculated as the P value of the calculation requirement, instead of obtaining a power value as the calculation in each slip time. The method can correct the defects of the method 1, but only improves the accuracy of power acquisition to a limited extent, can not solve the problem at all, and still can possibly have the problems, meanwhile, because the sampling value is increased, generally, one power value occupies 3 bytes of storage space, 60 storage spaces are increased in1 minute, 180 storage spaces are increased, and because the required quantity is divided into forward active power, reverse active power, reactive power 1 quadrant, reactive power 2 quadrant, reactive power 3 quadrant, reactive power 4 quadrant, split-phase active power, reactive power and the like, 4320 storage spaces are required to be increased at most, and the main control MCU chip is required to be reselected for the existing electric energy meter, so that the cost is increased.
3. And an electric energy accumulation method is adopted, an electric energy accumulation value E is obtained at each slip time t, the power is P=E/t at the moment, and other calculation methods are the same as the above. The method can completely avoid the problems of the method, but has the problems that 1) if the existing electric energy accumulated value with the accuracy of 0.01kWh is adopted as a calculated value or the electric energy accuracy accumulated value with the accuracy of 1 pulse is adopted, errors are necessarily caused, and the errors are larger. Assuming that the pulse constant of the electric energy meter is 6400imp/kWh, the current power is 1kW, the electric energy integrated value of 1min is (6400/3600) 60= 106.667 pulses, and the electric quantity of 0.0166 kWh. When the electric quantity calculation with the accuracy of 0.01kWh is adopted, the electric quantity calculation value of 0.0066kWh is lost, and when the pulse method is adopted, the calculation value of 0.667 pulses is lost. 2) If there is power in a slip time t for the previous period, the power is actually accumulated, but there is no power in the later period, and there is no load at this time, but in the calculation, p=e/t, t is still a complete slip time, so that P becomes smaller, and the load cannot be accurately reflected.

In this embodiment, the method includes the steps of:
Step 102, determining slip time t and power sampling period t 0, wherein the power sampling period t 0 is less than or equal to 1s.
For the power sampling period t 0, the smaller t 0 is, the more accurate the power judgment is, the more accurate the electric energy accumulation time is, the slip time is inevitably larger than the power sampling period, and the slip time t is more than or equal to 1min.
Step 104, in the ith slip time t, the initial electric energy accumulation time is 0, judging whether the power acquired in the current power sampling period t 0 is smaller than the starting power, if so, the electric energy accumulation time is not accumulated, otherwise, accumulating the current power sampling period t 0 to the previous electric energy accumulation time, and finally determining the electric energy accumulation time t E (i) in the ith slip time t, wherein i is {1, the number of the first place, n >1.
Step 106, obtaining the total power accumulation time T E in the demand period T according to the power accumulation time T E (i) in the ith slip time T, wherein the demand period t=n×t.
Optionally, the required period T is more than or equal to 5min.
Optionally, the total power accumulation time T E in the demand period T is calculated according to the following formula:
Step 108, calculating the electric energy pulse accumulation value D t (i) in the ith slip time t according to the pulse constant after frequency division and the electric energy accumulation time t E (i and the current power) in the ith slip time t.
Step 110, obtaining the total power pulse accumulated value D T in the demand period T according to the power pulse accumulated value D t (i) in the ith slip time T.

Alternatively, the demand P in the demand period T is calculated according to the following formula:

Where C is the pulse constant and k is the frequency division number of the pulse constant.
Optionally, the method further comprises dividing the pulse constant in the MCU of the electric energy meter.
Optionally, the frequency division number of the pulse constant is more than or equal to 5.
Specifically, in this embodiment, the pulse constant C of the electric energy meter is 6400imp/kwh, the power of the current device is 1kW, the instantaneous power of the device start is 8kW, the peak power is 14kW (the instantaneous value may be captured occasionally), the slip time T is set to 1min, the power sampling period T 0 is 1s, the demand period T is 15min, and the pulse frequency division number k is 10.
In the embodiment, the power is judged by sampling power every 1s within 1min of each slip time, the power is supplied for the first 30s and is larger than the starting power within 1min of the last slip time within 15min of the demand period, the power is not supplied for the last 30s, the power is supplied for the rest slip time and is larger than the starting power, the total electric energy accumulation time within 1-14 slip times within 15min of the demand period can be determined to be 14min, and the electric energy accumulation time within 15 th slip time is 30s, namely 0.5min, so that the total electric energy accumulation time T E within 15min of the demand period is 14.5min.
From the pulse constant after frequency division by 10, the power accumulation time within 1min of each slip time, and the current device power of 1kW, it is determined that:
in the first 14 slip times, the power pulse accumulated value of each slip time 1min is (6400×10× 1)/60= 1066.67 pulses, wherein/60 is because 1 min=1/60 h, and the time units need to be unified in the calculation process;
The 15 th slip time 1min has an accumulated value of ((6400×10×1)/60) ×0.5= 533.35 pulses, wherein/60 is because 1 min=1/60 h, and the 15 th slip time 1min has an accumulated time of 0.5min, so that×0.5 is also required, and the time units are required to be unified in the calculation process;
thus, the total power pulse integrated value D T is 1066.67 ×14+533.35= 15466.73 pulses in one demand period of 15 min.
According to the pulse constant C, the frequency division number k and the total electric energy pulse accumulated value D T, the electric quantity within 15min of one demand period in the embodiment can be calculated as follows:
ET＝DT/(C×k)=15466.73/(6400×10)kwh
Finally, according to a formula E T/TE, calculating to obtain a demand P within 15min of a demand period, wherein the demand P is as follows:
P=ET/TE=(15466.73/(6400×10))/(14.5/60)=1.000kw
The 14.5/60 is to convert 14.5min into hours to meet the unification in time units.
Based on the parameters of the above embodiments, if the existing calculation method mentioned in the background art is adopted, it can be obtained:

By using the slip equation of mode 1 mentioned in the background art, the calculated demand D may be:
D=(1+1+1+1+1+1+1+1+1+1+1+1+1+1+1)/15=1kW;
D=(1+1+8+1+1+1+1+1+1+1+1+1+1+1+1)/15=1.466kW;
D=(1+1+14+1+1+1+1+1+1+1+1+1+1+1+1)/15=1.866kW;
D=(1+1+1+1+1+1+1+1+1+1+1+1+1+1+0)/15=0.933kW;
D=(1+1+8+1+1+1+1+1+1+1+1+1+1+1+0)/15=1.400kW;
D=(1+1+14+1+1+1+1+1+1+1+1+1+1+1+0)/15=1.800kW。
Comparative example 2
In the manner 2 mentioned in the background art, the calculated demand D may be:
D=(1+1+1+1+1+1+1+1+1+1+1+1+1+1+1)/15=1kW;
D=(1+1+1.116+1+1+1+1+1+1+1+1+1+1+1+1)/15=1.007kW;
D=(1+1+1.216+1+1+1+1+1+1+1+1+1+1+1+1)/15=1.014kW;
D=(1+1+1+1+1+1+1+1+1+1+1+1+1+1+0.5)/15=0.966kW;
D=(1+1+1.116+1+1+1+1+1+1+1+1+1+1+1+0.5)/15=0.9744kW;
D=(1+1+1.216+1+1+1+1+1+1+1+1+1+1+1+0.5)/15=0.981kW。
Comparative example 3
By adopting the mode 3 electric energy accumulation method mentioned in the background art, the calculated demand D may be:
Taking pulse counting as an example, if there is one pulse number for 1 minute, then
D=((106*14+53)/6400)/(15/60)=0.96kW;
If the total of 15 minutes of pulses is accumulated, there is a possibility that less than one pulse number is lost before and after the time, the main reason is that when the demand begins to calculate, no pulse is present at the time
D=((105.667+106.667*13+53.335)/6400)/(15/60)=0.966kW。
In summary, compared with the existing demand calculation method, the demand calculation method of the application can more accurately reflect the load variation and has higher calculation accuracy.
