Method for measuring electric energy loss of high-energy-consumption smelting system

Abstract

The invention discloses a method for measuring the electric energy loss of a high-energy-consumption smelting system and relates to the field of detection. The method includes the following steps that firstly, a sensor is selected and installed; secondly, a sampling period is determined; thirdly, sampling is carried out; fourthly, the total electric energy quantity of all measuring points is acquired; fifthly, an electric energy loss value is acquired; sixthly, the electric energy loss value is output. According to the method, professional sensors like a PT is selected, accurate current and voltage values of measuring positions are acquired, and a foundation is laid for improving the accuracy of electric energy loss measurement; then, data are collected through a high-frequency analog-digital converter, the spline interpolation error compensation algorithm is utilized, and therefore a more accurate measured value is acquired, the total electric power and the total electric energy quantity value of all the measuring points can be calculated accordingly, and accurate electric energy loss conditions can be acquired according to an electric energy loss formula. The method is convenient to operate and has high market promotion and application value.

Description

technical field [0001] The invention relates to the detection field, in particular to a method for measuring power consumption of equipment using power in a high-energy smelting system. [0002] Background technique [0003] Electric energy loss is bound to occur when electric energy is used as power or heating source, but if the electric energy loss of electrical equipment can be accurately measured, the cause of electric energy loss can be analyzed in a targeted manner, which is helpful for reducing loss, saving energy and reducing It is very necessary to accurately measure the power loss and improve the power loss situation. Especially in high-energy smelting equipment, the measurement of power loss, the accurate diagnosis of the cause of the loss, and the improvement of the system can greatly reduce the cost of production. [0004] There are no mature products in the prior art for monitoring energy consumption, especially for accurate measurement of power consumption o...
