Using the latest integrated circuit chip control technology, in order to "dynamic tracking energy management control system software" and "fuzzy neural control software" as the leading factor, with the computer technology, CVT technology as the means, dynamic tracking detection and feedback of motor running change and the change of the power grid, power consumption and the operation feedback signal operation, control, change of the motor power supply situation at any time, in the process of dynamic adjustment motor running voltage and current, make the optimal operating voltage and current, thus effectively avoid motor caused by output excessive waste of electric current. Without changing under the normal operation of the motor system, guarantee the output torque and the load demand an exact match, keep the motor running in the best state, to achieve automatic intelligent control of the motor, maximum limit save power. This technology can be used for the fan, water pump, air compressor motor drive series such as energy saving, suitable for factory buildings and buildings, wide coverage of industries, including steel, power, chemical industry, metallurgy, cement, light industry, medicine, business and other fields. Circulating water system, cooling water pump, went on a drag way, has prepared cutting function, 8 hours each operation can be automatically or manually switch to another under the same frequency converter motor run, according to the terminal temperature automatically adjust pump speed; Heat pumps, using yituo two way to run the same rev. Stop, according to the network temperature automatic closed-loop adjustment, has the high limit protection to ensure that the cooling tower does not exceed the maximum capacity; Cooling fan, using yituo two ways according to the radiator outlet temperature to realize closed loop control, and set the time automatic cutting operation points three times every day. In general the system using the optimization control theory, fuzzy control, automatic computer closed loop control technology, such as energy saving rate of 45%. Purify dust removal fan system, using a inverter tow three motors. In maintenance or motor, inverter breaker failure by high voltage switch cabinet, the manual switch to one or two motor in power frequency operation, meet production purification dust purification system. Frequency control mode is controlled by inverter ontology and field remote control two kinds, the scene has switching state, frequency setting and display and tripping functions. This system USES a 32 bit high speed DSP chip, PLC control technology, precise algorithm controller structure adopts enclosure structure, each control unit board use the large scale integrated circuit such as FPGA, CPLD and the surface welding technology, using industry communication protocol and the optical fiber communication at the same time, make the system have high reliability, energy-saving rate of 69%. Strong energy saving renovation of oil air-cooled transformer adopts temperature closed loop control, through the industrial computer, PLC control technology for 50000 tons of electrolytic cell strong rectifier transformer oil energy saving renovation of air cooling system for oil pump and fan automatic control, to keep its temperature and environmental temperature difference within the scope of the set, energy-saving rate of 50%.

      Through the establishment of energy management system, the real-time data collection, statistics and analysis of energy consumption, and establish the energy usage plan and maximum demand control system, the further optimization of energy distribution and utilization of management so as to achieve the effect of energy saving.

      Festival energy = 25304400-10296000 = 25304400 kWh, equivalent to BiaoMei 5177.8 tons (conversion coefficients by 3.45 x 10-4 tce/kWh), according to the local industrial electricity price (0.51 yuan/kWh) for the user to save electricity, 7.65 million yuan a year.
