Core Tip: First, the analysis of the characteristics of electricity users in the industry Cement manufacturing under the non-metallic mineral manufacturing industry directory of cement, lime and gypsum manufacturing industry, is heavy industry, refers to

The analysis of the power consumption of industry users
The textile industry can be subdivided into cotton production, chemical fiber textile and printing and finishing processing, wool textile and dyeing finishing, linen textile, silk spinning and finishing, textile and finished products, knitwear, knitted fabrics and their products, according to the national production industry.
The general capacity of the textile industry, most of the use of high voltage power supply, set up special substation (distribution). The users in this industry are basically continuous 24 hours a day, the electricity load is relatively average, the production load accounts for about 95% of the total load, and the office electricity (including living lighting) and other loads account for about 5% of the total load.
The main production process: spinning carding process (open cotton - Cotton - Cotton Blending - roll), carding (carding - impurity mixing strips), strip rolling process (and and drafting rolls), combing (impurity - comb - drawing - strips) and drawing (drafting and - mixing strips), roving (draft - twisting, spinning process (Draft) - twisting - winding - forming), winding process (winding and forming impurity), twisting process (twisting winding, yarn - forming) process and package process.
The main production process of weaving is: warping process, sizing of sizing, passing through process, weaving process and finishing process.
Classification of user equipment in textile industry
Two, industry users participating in peak power rationing ability analysis
1. the industry is generally 24 hours continuous production, the electricity load is more average, the load curve is relatively stable, the load rate is up to 95%.
The 2. industry is labor-intensive industries, no important load, there are a number of production lines, in the middle of emergency peak ability, more suitable for the holiday to participate in the stage of peak power rationing.
Three, industry users to participate in the technical scheme of the peak power
(1) IV level participation scheme for notch grade
The 1. stage of the peak
1) first, the user saving power is advocated:
A. no lights in the corridors, passages, toilets and other places with good natural lighting.
B. office lights in one stop; indoor temperature is higher than 30 degrees centigrade to open air conditioning, air conditioning temperature setting is not less than 28 degrees.
C. reduces standby time for office equipment: office equipment mainly includes computers, printers, facsimile machines, copiers and water dispensers. After the end of the work, all electrical equipment in the office will be closed in time and the office electrical equipment is not in standby state.
D. closes the landscape lighting.
2) to reduce or stop blowing machine, pre carding machine, carding machine, roving machine, drawing frame, combing machine and production load.
2. emergency peak
During the period from 8:00 to 22:00, the non productive loads such as lighting, office air conditioning, office load and so on should be reduced. During the period of the "to" period, there will be no production load such as lighting, office air conditioning, office load and landscape lighting.
To reduce or stop blowing machine, pre carding machine, carding machine, roving machine, drawing frame, combing machine and production load.
(two) notch grade III level participation scheme
The 1. stage of the peak
Based on the implementation of IV scheme, to reduce or stop the workshop workshop lighting, air-conditioning and ventilation equipment, humidifiers and other auxiliary production workshop load; reduce or stop blowing machine, pre carding machine, carding machine, roving machine, drawing frame, combing machine and production load.
2. emergency peak
Based on the implementation of IV scheme, to reduce or stop the workshop workshop lighting, air-conditioning and ventilation equipment, humidifiers and other auxiliary production workshop load; reduce or stop blowing machine, pre carding machine, carding machine, roving machine, drawing frame, combing machine and production load.
(three) notch grade II level participation scheme
The 1. stage of the peak
On the basis of implementing the III level plan, we should reduce or discontinue the load and other production loads of cryogenic nitrogen making machines, refrigerators, air compressors, fans, pumps, steam boilers and other power plants.
2. emergency peak
On the basis of implementing the III level plan, we should reduce or discontinue the load and other production loads of cryogenic nitrogen making machines, refrigerators, air compressors, fans, pumps, steam boilers and other power plants.
(four) notch grade I level participation scheme
The 1. stage of the peak
All auxiliary productive load and productive load are discontinued.
2. emergency peak
All auxiliary productive load and productive load are discontinued.
Four, industry users participating in peak power rationing and precautions of risk
The textile industry is a labor-intensive industry, no important load, in peak power rationing there is no security risk, enterprise workers do reasonable scheduling work. The peak power rationing to keep the total load capacity of 10%, to ensure the fire control system (automatic sprinkler system, blower etc.) and living quarters electricity demand for electricity.
Therefore, the industry users to participate in managing, enterprises should be based on their actual situation, scientific and reasonable preparation of internal emergency plans, actively cooperate with managing the implementation, to prevent accidents, undertake the social responsibility at the same time to minimize the loss.
Five, the function and application of intelligent power monitoring
5.1 project overview
Changshu polyester Co., Ltd. (formerly Changshou City polyester factory) is a high-strength and low stretch polyester filament and FDY high strength low shrinkage polyester industrial yarn (fine denier) professional production enterprise, and has the right of self import and export. The company was founded in 1983, is located in the Yangtze River Delta, Changshou City City Town Dong xu. The factory covers an area of 49900 square meters, with a building area of 27319 square meters, with a total of four production areas. Because the power consumption of Changshu polyester factory is relatively large, and in response to a series of policies and measures promoted by the State Council to promote energy saving and emission reduction, it is better to monitor and manage the distribution system. Therefore, the background power monitoring and power management system is set up, and the intelligent management of distribution is carried out.
The power distribution system of the factory is mainly produced by the high voltage motor line of the first floor of the factory and three
