Abstract

The invention provides steel production planning-based energy forecasting system and forecasting method. The forecasting system consists of a data acquisition network, an industrial ring network and a management network, wherein field real-time data of a measuring instrument and a programmable logic controller (PLC) is acquired through the data acquisition network, and output and consumption forecasting of an energy consumption unit in the future is realized by the energy forecasting module according to data of production plan, maintenance plan and equipment state acquired from enterprise resource planning (ERP) and manufacturing executive system (MES). The system can accurately forecast the energy output and consumption of a single unit or the whole enterprise according to the production plan, the maintenance plant and equipment state and other real time data, and provides basis for reasonable dispatching of energy of steel enterprises, thereby effectively reducing energy waste of the steel enterprises.

Description

technical field [0001] The invention belongs to the field of energy forecasting for iron and steel enterprises, in particular to an energy forecasting method based on iron and steel production planning. Background technique [0002] Energy costs account for 13%-15% of the total cost of steel production. Energy prices are still on the rise, which will bring huge market competition pressure to energy-consuming iron and steel enterprises. It can be seen that saving energy, reducing energy consumption and improving efficiency will be a long-term strategic goal adopted by the iron and steel industry in the fierce market competition. At present, the general energy dispatching method of steel companies is a management mode of manual post-dispatching, which cannot reasonably allocate energy and power in advance, balance production, and reduce energy waste. Contents of the invention [0003] In order to provide dispatchers with energy production and consumption data 12 hours in a...
