Energy efficiency analysis system of interlocking equipment

Abstract

The invention relates to an energy efficiency analysis method of interlocking equipment. The energy efficiency analysis method comprises: data sampling: carrying out equal-time and equal-distance sampling on energy consumption correlation parameters of at least two sets of equipment in the interlocking equipment, so as to obtain sampled data within certain time; data pre-processing: carrying out the data pre-processing on the actually measured sampled data, eliminating abnormal data therein and complementing missing data; framing operation: dividing the sampled data subjected to pre-processing of each set of equipment into a plurality frames through adopting an overlapping and sectioning manner, wherein each frame corresponds to one time period with equal duration and a frame shifting length of each frame is smaller than a frame length; correlation coefficient calculation: taking the sampled data in each frame as a foundation and calculating a correlation coefficient rXY in each frame of the energy consumption correlation parameters of at least two sets of equipment in the interlocking equipment; abnormity judgment: taking a frame with the correlation coefficient lower than a judgment threshold value as an abnormal frame. The energy efficiency analysis method of the interlocking equipment, provided by the invention, can be used for assisting to check reasons for forming interlocking abnormity and guiding the equipment to be correspondingly adjusted; whole operation of a system can be more stable and more energy can be saved through adopting the method.

Description

technical field [0001] The invention relates to a method for analyzing energy efficiency of linkage equipment. Background technique [0002] In the production of modern enterprises, monitoring and analyzing the energy consumption related parameters of each equipment in the production equipment is an effective method to understand and control the overall energy consumption related parameters of the production equipment, but the monitoring of the energy consumption related parameters of the production equipment is often isolated in the existing technology. That is to say, only the independent energy consumption-related parameters of the equipment are monitored and analyzed, and the linkage relationship between the equipment is ignored. Although this method can reduce the overall energy consumption-related parameters of the equipment to a certain extent, it does not consider the running time of the linkage equipment. The influence between each other, so the optimization effect ...

[0002] In the production of modern enterprises, monitoring and analyzing the energy consumption related parameters of each equipment in the production equipment is an effective method to understand and control the overall energy consumption related parameters of the production equipment, but the monitoring of the energy consumption related parameters of the production equipment is often isolated in the existing technology. That is, only independent monitoring and analysis of energy consumption-related parameters of equipment is carried out while ignoring the linkage relationship between equipment. Although this method can reduce the overall energy consumption-related parameters of equipment to a certain extent, it does not consider the running time of linkage equipment. The influence between each other, so the optimization effect of its energy consumption related parameters is not ideal
