Embodiment Construction

[0030] The invention provides a metering method for saving electricity, which compares and calculates the electricity saving rate and electricity saving method by controlling the start and stop of the electricity saving equipment and counting the electricity metering data during the start and stop period, and realizes the method through the electric meter.

[0031] Metering energy saving is composed of sequentially executed metering cycles, and each metering cycle is composed of two steps: calculating the power saving rate and measuring the energy saving.

[0032] The energy-saving rate measurement method is to control the input and removal of the energy-saving equipment, measure the power difference between the input and removal of the energy-saving equipment, and calculate the energy-saving rate by the ratio of the power difference to the power consumption. The calculation formula is as follows:

[0033] K=(Wn-Wy) / Wn (Wn is the power consumption during the equipment disconne...

Abstract

The invention discloses a method for metering power saving amount and an ammeter. The method and the ammeter realize real-time calculation of power saving rate and power saving amount through a mode of controlling start and stop of equipment and real-time online energy saving calculation. The assessment method is straightforward, high in user acceptance and accurate in assessment result, preventsthe defects of long period of conventional power saving assessment and low assessment accuracy, provides a new verification method for power saving effect, and greatly promotes rapid promotion and application of power energy saving technology and products.

Description

technical field [0001] The invention relates to the technical field of electric energy saving measurement, in particular to a method for measuring energy saving and an electric meter. Background technique [0002] In the field of energy saving, after adding energy-saving equipment, it is necessary to evaluate the energy-saving and economic benefits, which often requires an evaluation cycle of more than half a year, which is not only long, but also easily affected by load fluctuations, which seriously restricts energy-saving technology. Currently, there is no simple and fast energy-saving measurement method that is convenient and recognized by both parties on the market. In view of the above problems, the present invention can quickly and easily calculate and verify the energy-saving rate, and calculate the energy-saving online in real time. Contents of the invention [0003] In order to solve the above problems, the present invention provides a metering method of energy sa...
