Abstract

The invention relates to a demand calculation method for a smart meter, which is characterized in that it includes the following steps: step (1), detecting whether the smart meter has a clock calibration or a demand period change, and if there is a clock calibration, go to step ( 2), if there is a periodic change in demand, go to step (4); step (2), collect the time t1 before clock calibration and the time t2 after calibration; Clear the data, and calculate the demand within the demand cycle at the time t2 after calibration; step (4), collect the time point t3 when the demand cycle changes and the cycle T′ after the change of the demand cycle; step (5 ), clear the electricity data before the time point t3 when the demand period changes, and calculate the demand in the period T′ after the demand period change, and turn to step (6). Step (6), using the demand calculation method to calculate the demand in the demand cycle when the smart meter has not changed. The calculation method is more reasonable and accurate.

Description

technical field

[0001] The invention relates to the field of smart electric meters, in particular to a method for calculating the demand of the smart electric meter. Background technique

[0002] Smart meters are one of the basic equipment for data collection in smart grids (especially smart distribution networks). Foundation. Demand is an important function in smart meters. In a specified time period, the maximum average power measured in the demand cycle is called the maximum demand of electric energy. The measurement of the maximum demand of electric energy is of great significance to the electric energy management of power lines or power networks. For the power supply related departments: it is beneficial to the reasonable adjustment of the line and optimal scheduling work; for the user, knowing the maximum demand of the line and adjusting the load distribution can make the system stable without increasing the capacity of the transformer.
