First, the industry user electricity characteristics analysis

The food and beverage industry can be subdivided into agricultural and sideline food processing industries (including grain milling, feed processing, vegetable oil processing, slaughtering and meat processing, fruit and vegetable processing, etc.) according to the national production industry, food manufacturing industry (including bakery products manufacturing, convenience foods Manufacturing, canning, etc.), beverage manufacturing (including the manufacture of wine, soft drinks, etc.).

The main agricultural and sideline products processing processes: raw materials - slaughtering - cooling - cutting - processing - processing - cooking - cooling - sterilization - frozen - Packaging - custody.

Canned fruits and vegetables processing mainly for the production process: cleaning - pre-treatment - pre-cooling - frozen - Canning - Sealing - sterilization - rubbing tank - storage.

The main electrical characteristics of the industry for pipeline operations; continuous operation of refrigeration equipment; fruits and vegetables seasonal seasonal electricity production significantly; export-oriented and strong demand during the contract period.

Second, the industry users participate in the peak load capacity analysis

1. The industry electricity load and continuous load from the time, season, climate impact.

2. Emergency peak power cut You can quickly disable office, lighting, computer fax machines and other office equipment, at night, you can stop the plant lighting and other equipment, and disable some auxiliary production equipment, such as: cooling Units, air conditioners, boilers, but without prejudice to the safety. Emergency peak crossing ability is weak, purification recycling equipment: such as cross-tube coolers, electric tar, tornado tarry, ammonia washing tower, benzene tower, desulfurization tower and other important (high risk) electricity load, unfit to participate in the fast To avoid the peak.

3. The industry users staggered peaks can be arranged by the centralized maintenance and production cuts and other ways to carry out, such as the use of centralized maintenance methods, only to retain the workshop lighting, accident lighting, maintenance lighting and other maintenance equipment power supply, the general maintenance of about 1,000 kilowatts maintenance Load can be; such as the use of shutdown mode, you can gradually stop coking equipment and ancillary support systems to reduce the production load, peak shifting effect.

Third, the industry users involved in the peak load power technology solutions

(A) gap level IV level participation program

1. Staggered peaks:

Under the premise of ensuring safety, stop the oven at 8: 00 ~ 22: 00 for stuffy oven treatment, reduce production, so as to achieve the peak shifting effect.

2 emergency peak

1) After receiving the peak load command, input the limit load quickly and then release the load gradually to resume normal production according to the instruction.

2) prioritize air-conditioning systems, office and lighting system peak, and then gradually release the load according to the instructions.

(B) Gap level III participation program

1. Staggered peaks:

On the premise of ensuring the safety, on the basis of implementing the IV plan, part of the machining equipment will be added to stop the peak at 8: 00 ~ 22: 00 and coke ovens will be treated in a fryer to further reduce the output so as to meet the peak load requirement .

2 emergency peak

1) After receiving the peak load command, input the limit load quickly and then release the load gradually to resume normal production according to the instruction.

2) On the basis of the implementation of the IV plan, some additional machining equipment will be involved in the shifting of peak load to reduce part of the production load so as to meet the peak load shifting requirement. Then, the load will be released gradually to resume normal production according to the instructions.

(C) Gap level II level participation program

1. Staggered peaks:

1) On the premise of ensuring safety, on the basis of implementing the plan of level III, all the machining equipment will be added and stopped at 8: 00 ~ 22: 00, and the coal blending system equipment will further reduce the output so as to meet the requirements of peak shifting.

2) for the slow response time purification purification equipment in advance to participate in the preparation of peak cross-peak, to ensure that all load-limited full-time participation in the wrong peak.

2 emergency peak

1) After receiving the peak load command, input the limit load quickly and then release the load gradually to resume normal production according to the instruction.

2) Based on the implementation of the Level III program, quickly stop all machining equipment and equipment on the coal blending system to meet peak load requirements, and then gradually release the load as instructed.

(D) Gap level I-level participation in the program

1. Staggered peaks:

Taking into account the larger power gap, you can arrange the entire plant overhaul, leaving only the maintenance load required by the equipment.

2 emergency peak

1) After receiving the peak load command, input the limit load quickly and then release the load gradually to resume normal production according to the instruction.

2) Taking into account the safety of the industry's production and the ease of resumption of production, no additional production equipment will be imposed on the basis of the implementation of the Level II program. Then gradually release the load according to the instructions.

Fourth, the industry users participate in the peak load risk and precautions

1. A sudden power outage occurred in the furnace, fire and other parts of the production area of the production enterprise, which easily lead to the gas leakage, resulting in environmental pollution and causing serious poisoning or economic loss to the relevant personnel. It is proposed to adopt centralized production , Focus on maintenance methods, ahead of completion of this month's production tasks, the remaining number of days to avoid peaks or annual maintenance.

2. From a safety point of view, such as purifying the product recovery workshop (gas purification), a sudden power outage will result in a major accident due to the fact that the gas from the coke oven reaches 82 ℃, such as power failure, fan shutdown and gas spill Explosion and poisoning and other personal injuries. For coke oven, such as power outages, coke oven will be scrapped, the same gas may explode.

Therefore, the industry users should develop effective contingency plans as early as possible, participate in the peak should take the initiative to cooperate with the implementation of peak shifting, timely communication with the power supply companies, should take maintenance or shift, etc., to avoid the use of forced pull or remote control equipment to limit power and eliminate Malignant accidents take the initiative to shoulder social responsibility, while minimizing losses.

Fifth, the smart power monitoring functions and applications

5.1 Project Overview

India's Uttam Steel builds a 500,000-mt pig iron mill in Wardha, Wardha (Wardha district has abundant coal and iron ore resources, convenient transportation and road and rail access) The project includes a sintering plant and a 500,000-ton coking plant. The project is estimated to cost Rs 11 billion (US $ 228 million).

500,000 tons of coking plant construction includes coal preparation plant, coking plant, gas purification plant and other production facilities and supporting public auxiliary facilities; as other plant energy supply area, power distribution security is particularly important, the requirements are higher, in the Power control must require safe, reliable, fast, relying on manual control of the site can not meet the actual requirements of the project. An Kerui Electric Co., Ltd. on the company commissioned by Hyde Lixi, India Coking Plant on-site commissioning and commissioning of intelligent power system; the main completion of the coking plant 6.6KV distribution system and 0.4KV power distribution system for centralized monitoring to ensure coking Factory power supply system is operating normally.
