Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The existing electric energy meter is provided with a clock and a time control circuit which are accurate in timing, small in time interval error and day error and accurate in connection or switching. The time base in the electric energy meter generates a second signal through frequency division, and the second signal generates a clock signal such as time division and the like through counting; the time control part of the electric energy meter segments the clock signal and controls the opening and closing of the peak control gate, the valley control gate or the flat control gate, thereby realizing the time-sharing multi-rate metering of the electric energy.
The existing electric energy meter clock adopts a lithium battery as an operation power supply, and under the condition of insufficient electric quantity of the battery, an external circuit is stopped from passing electricity, so that the clock cannot normally keep running and returns to a reset state. For example: when the electric energy meter normally runs, the clock is 2019, 9, 18 and 00, the battery energy is exhausted, and the clock is reset to 2000, 1 and 00. Once the clock of the electric energy meter is abnormal, the clock of the electric energy meter is different from the standard time (Beijing time) by several minutes or even hours. Besides the deviation between the factory clock setting of each electric energy meter and the Beijing time, the main reason is that the parameters of the clock crystal oscillator change, particularly the output frequency of the crystal oscillator changes under the influence of the environmental temperature in the operation process, and the temperature characteristic of the clock crystal oscillator shows that the clock day error exceeds the standard of 0.5s/d at 23 ℃ under the condition that the environmental temperature deviates from the calibration temperature and the clock is slow. The daily time errors are accumulated continuously, so that the clock deviation of the electric energy meter becomes larger and larger along with the running time, and the clock deviation is individual or even larger. If the electricity consumption data of the time period directly acquired from the electric energy meter is not consistent with the electricity consumption data required by the standard time, the time period electricity quantity calculated by the electric energy meter does not truly reflect the electricity quantity used by the user in the corresponding time period, and therefore the time-sharing multi-rate metering of the electric energy meter is inaccurate.
Wherein, the standard time refers to the standard time of the national time service center.
Therefore, the embodiment of the application provides a method and a device for calculating time-sharing electric quantity of an electric energy meter and computer equipment, and is used for solving the technical problem that time-sharing electric quantity stored in a memory is wrong due to the fact that peak time, flat time and valley time-sharing electric quantity data calculated by the electric energy meter are not in one-to-one correspondence with time-sharing electric quantity data of actual time when a clock of the existing electric energy meter fails.
The first embodiment is as follows:
fig. 1 is a flowchart illustrating steps of a method for calculating time-sharing electric quantity of an electric energy meter according to an embodiment of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for calculating time-sharing electric quantity of an electric energy meter, which is applied to a metering automation system, and includes the following steps:
s1, acquiring forward active power sums with an interval of 1 hour every day of electric energy meter settlement to obtain 24 summary tables of the forward active power sums;
s2, respectively extracting forward active power sums of a first time point and a last time point in the peak time period, the ordinary time period and the valley time period from the summary table according to the peak time period, the ordinary time period and the valley time period;
and S3, calculating the peak electric quantity, the average electric quantity and the valley electric quantity of the time-sharing electric quantity for the forward active power extracted at the first time point and the last time point according to a time-sharing electric quantity calculation rule.
In the embodiment of the invention, the time-sharing electricity quantity is that electricity consumption of a peak time period, a valley time period and a normal time period is respectively measured by adopting the preset division of the peak time period, the valley time period and the normal time period, and the user property of charging by adopting the time-sharing electricity quantity is mainly common industry and large industry users.
The peak time zone is a time zone in which a large amount of electricity is used by the user during one day, the valley time zone is a time zone in which the amount of electricity used by the user during one day is small, and the normal time zone is another time zone in which the user excludes the peak time zone and the valley time zone during one day. The peak electric quantity refers to the electric quantity used by a user in a peak time period of a day, the valley electric quantity refers to the electric quantity used by the user in a valley time period of the day, and the flat electric quantity refers to the electric quantity used by the user in a flat time period of the day.
In the embodiment of the invention, the time segmentation is adopted by taking 24 hours as a cycle, and the peak time period is 14 to 17 points and 19 to 22 points in the 24-hour system; the normal time period is 8 to 14 points, 17 to 19 points and 22 to 24 points in a 24-hour system; the valley period is from 0 to 14 points in the 24-hour system, and the electric energy consumed in the period is referred to as time-sharing electric energy. For example, the amount of power consumed by the user during the valley period is referred to as a valley power amount.
In the embodiment of the invention, the current positive activities of the electric energy meter are always accumulated in real time, and the metering automation system of the electric energy meter collects the meter codes of the electric quantity used by the user to the electric energy meter every hour.

The technical problem that time-sharing electric quantity stored in a memory is wrong due to the fact that peak time-sharing electric quantity data, flat time-sharing electric quantity data and valley time-sharing electric quantity data of the electric energy meter are not in one-to-one correspondence caused by the fact that a clock of an existing electric energy meter breaks down is solved.

Note that, according to the forward active total in fig. 3, the peak electric power is (280.98-280.97) + (281.00-280.99) is 0.01+0.01 is 0.02 kwh. The average electric quantity is (280.97-280.90) + (280.99-280.98) + (281.15-281.00) 0.07+0.01+ 0.15-0.23 kwh. The grain average value is 280.90-277.93-2.97 kwh. At this time, the correct time-sharing electricity quantity of the user is obtained through calculation, the electricity consumption quantity of the user in the peak time period, the ordinary time period and the valley time period can be respectively obtained, and the daily electricity consumption expense of the user can be conveniently calculated.
