Description

technical field [0001] The invention relates to the field of energy management, in particular to an energy management and control system. Background technique [0002] In the prior art, iron and steel enterprises are large energy consumers, and electricity consumption accounts for about 10% of the total local electricity consumption. After nearly ten years of industry development, the iron and steel industry has experienced overcapacity, and reducing costs has become an inevitable choice. Judging from the survey and the known situation of several iron and steel enterprises, in terms of system, each major steel enterprise has set up an energy management leading group and an energy management (control) center, and each branch factory is equipped with corresponding management and technical personnel . However, there is an overall disconnection in management methods, that is, there is no necessary connection between the energy management (control) center and each branch factor...

Problems solved by technology

However, there is an overall disconnection in management methods, that is, there is no necessary connection between the energy management (control) center and each branch factory, energy assessment generally has no substance, and the energy center only knows the total energy consumption of the branch factory. The specific classification and data of the plant's energy consumption cannot be grasped. Even the branch factory itself has no detailed energy classification and data indicators due to historical conditions. This situation has continued year after year. In addition, the electricity consumption data has always been Acquisition is an important technical link of the energy management and control system. So far, many systems with different principles and functions have been developed.

[0003] The application number is CN201120003322.3 and the energy management and control system described in the invention, although it can realize the transformation from single equipment energy saving to system optimization energy saving, but its control program is relatively complicated, the equipment operation is relatively cumbersome, and the investment is large.

[0004] The application number is CN201320134324.5, an energy management and control system for offshore oil production equipment, although it is equipped with the electric energy meter and the ultrasonic flowmeter, so as to control the energy consumption and crude oil consumption of offshore oil production equipment monitor, and transmit the monitored data to the master station computer for centralized monitoring through the data acquisition device, once a certain value exceeds the set value, the master station computer controls the alarm device to give an alarm, Therefore, the energy management and control system of the offshore oil production equipment can achieve fine control of the energy of the offshore oil production equipment, and further, it is conducive to efficient use of energy, but its system structure is relatively complicated and the degree of automation is not high. Signal transmission efficiency is low
