Problems solved by technology

Existing energy-saving renovation measurement methods and devices cannot measure the power consumption of the measured system under different operating conditions. The energy-saving data before and after energy-saving renovation needs to be processed manually, which is prone to errors caused by human factors, resulting in inaccurate power-saving data

Embodiment 1

[0028] This embodiment provides a method for energy saving measurement such as figure 1 As shown, the method includes the following steps:

[0029] S101. Collect the current of the system under test before the energy-saving renovation and compare it with the preset current threshold before the energy-saving renovation to determine the operating state of the system under test before the energy-saving renovation;

[0030] The system under test is also called the motor system, that is, the motor system undergoing energy-saving transformation, and also the motor system that needs the measured energy-saving data. Specifically, when the system under test is running before the energy-saving transformation, the real-time current of the system under test is collected, and the collected real-time current is compared with a preset current threshold to determine the running state of the system under test. It should be noted that the preset threshold is used to distinguish the operating s...

Abstract

The invention discloses an electric-energy-saving metering method and device. According to the electric-energy-saving metering method and device, the real-time currents of a tested system are collected before and after reform and compared with a preset current threshold value, the operation states, existing before and after reform, of the tested system are determined, the electric energy data classifications of the tested motor systems under different running states are recorded and stored, after energy-saving reform is completed and before a motor runs, the electric energy data obtained before energy-saving reform are frozen and stored in a first mode, and electricity saving data are calculated according to the electric energy data, existing before and after energy-saving reform, of the tested system under the same corresponding running state. The electric-energy-saving metering method and device are suitable for measurement of the electric energy data of the tested system before and after energy-saving reform under multiple running states, all the data can be displayed, stored and transmitted remotely, metering is accurate and understandable, and operation is convenient.

Description

technical field [0001] The present application relates to the field of energy-saving measurement of electric energy, in particular to a method and device for energy-saving measurement of electric energy. Background technique [0002] With the continuous progress of society and the continuous development of science and technology, the energy problem is the most urgent problem facing human development. In order to fundamentally solve the energy problem, in addition to finding new energy sources, energy saving is the key and the most direct and effective measure at present. Energy saving is the application of methods that are technically reliable, economically feasible and reasonable, and environmentally and socially acceptable, to effectively use energy and improve the energy utilization efficiency of energy-consuming equipment or processes. [0003] According to the relevant national regulations, in terms of energy saving, energy consumption measurement devices are complete, ...
