Problems solved by technology

Judging from the number of cycles required to be 200,510 times, the program needs to be run repeatedly here, which is very time-consuming, and there will be a "false crash" phenomenon, which is not suitable for the calculation of electric meter compensation.

Embodiment Construction

[0031] Such as figure 1 Shown is the method flowchart of the method of the present invention: the compensation calculation method of this load curve provided by the present invention comprises the following steps:

[0032] S1. The energy meter records the time point of power-off and power-on again; the record time point includes recording the year, month, day, hour and minute of power-off and power-on again, for example, the power-off point is January 1, 2017 At 10:05 on the day, the record is 17.01.01.10:05;

[0033] S2. The electric energy meter converts the time point of power-off into the time from a specific time point as the starting point, and at the same time converts the time point of re-power on into the time from the specific time point as the end point; the specific time point can use the existing general The time point, that is, 0:00 on January 1, 2000; the starting point is the number of minutes from the power-off time point to the specific time point, and the e...

Abstract

The invention discloses a compensation calculation method for a load curve. The method comprises: a power-down time point and a re-power-on time point are recorded; the power-down time point is converted to be time of a distance specific time point and the time is used as a starting point, and the re-power-on time point is converted to be time of a distance specific time point and the time is usedas an end point; with a non-circular calculation method, the number of records needing to be supplemented between the starting point and the end point is calculated; and one-time supplementing of obtained record number data is carried out by starting with the recorded power-down time point to complete compensation of a load curve. According to the invention, the non-circular calculation method isused for replacing the original circular calculation method to calculate the number of data needing to be supplemented, so that the function implementation is simplified; the statement is concise. With the n calculation method, the product performance is improved substantially; and the calculation method is especially suitable for occasions needing repetitive invoking. Moreover, the method that is simple and reliable has the fast response; the operation is done quickly; and the national standard requirements are met.

Description

technical field [0001] The invention specifically relates to a compensation calculation method of a load curve. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's daily production and life, bringing endless convenience to people's production and life. [0003] As the only part of electric energy metering in the power system, the importance of the electric energy meter is self-evident. At present, in the electric meter (with battery power supply and clock function) industry, the load curve is a very common and very important part. The load curve means that the meter records the voltage, current, electricity and other information during the operation of the meter at a fixed interval (such as 1 minute, 5 minutes, 10 minutes, etc.), and draws these information into a curve in chronological order. The load curve has...
