Analyze the specific situation of self-owned power plants from the perspective of environmental protection, energy saving and emission reduction? What is the connection with isolated network operation? Electric energy is one of the main energy sources consumed by high-energy products. Data show that the production of one ton of electrolytic aluminum needs to consume10.5 million kwh of electric energy, and the ferromanganese alloy is as high as 4,000 kwh/ton. According to statistics, in the cost of high energy-consuming products, the electricity fee should account for at least 20%, and the cost of ferrosilicon accounts for 70% at the highest. It can be seen that electric energy is the lifeblood of high energy-consuming industries such as steel, electric power, cement, coal, chemical industry, coking and ferroalloy. How to adopt new technologies, new processes and new equipment to transform traditional industries, reduce energy consumption per ton of products and reduce electricity price expenditure are the main factors for high energy-consuming enterprises to reduce production costs and improve market competitiveness, and are also the key to their survival and development. Therefore, the urgent task is to solve the problem that enterprise-owned power plants are not connected to the grid (that is, isolated networks) and directly supply power to high-energy-consuming projects, give full play to the efficiency of power generation equipment in self-owned power plants, and reduce power consumption costs.

Patent technology of load regulation system invented by Shanxi Bosek Electric Power Technology Co., Ltd. (invention patent number: ZL200610065761.0; +0.0; Patent number of utility model: ZL200620008044. x)。 It is specially designed for enterprise-owned power plants. In the case of weak ties or not connected to the grid, the problem that the power plants owned by these enterprises can't generate electricity, or although they can barely generate electricity, the generator sets can't operate stably due to the fluctuation of power load is completely solved. Successfully realize the off-grid (i.e. isolated network) operation of enterprise-owned power plants, reduce the power consumption cost of kWh, and directly supply power to high energy-consuming products. This patented technology comprehensively applies many new technologies, such as automatic control, electric energy and heat energy conversion, energy storage and recovery, which not only solves the automatic control of load fluctuation adjustment of enterprise-owned power plants, but also completely solves the problem of load fluctuation adjustment caused by frequent switching of high-power loads in the production process of high-energy-consuming projects, so that the generator set can run safely and stably. At the same time, it can directly provide high-energy-consuming projects with the same quality as large power grids to meet the demand of production and domestic electricity.

As a high-tech industrial company, the company leaders led all employees to follow the green economy industry and sustainable development strategy advocated by the state, and devoted themselves to the research and development of the power industry in line with the business philosophy of "continuous progress and Excellence", and obtained two national patents, namely, a power load regulation system and method (invention patent number: 2006400657 10) and a power load regulation device (practical). In Changzhi City, Shanxi Province, our company tailored for some non-grid-connected power plants that adopted this technology, which improved the disadvantages of traditional non-grid-connected power plants in regulating power load through valve venting, thoroughly solved the long-standing problems of energy waste and environmental noise pollution in non-grid-connected power plants, and achieved gratifying results in the safe and stable production of 2*6000W coal gangue generator set and 2* 12MW coking waste heat generator set, and the annual economic benefits increased by 2-5 times.
