Detailed Description
Firstly, the total energy required by the whole year, the total energy consumption of the whole year and the total natural gas consumption are converted into standard coal, and the standard coal is unified (for example, 80 units of standard coal are required in the whole year, and the electric energy and the natural gas purchased in the current year are 100 units of standard coal). As shown in figure 3, by comparing, the total energy efficiency can be found, and all waste and recyclable places can be searched, so that the recycling of the air compressor waste heat and the flue gas after the natural gas is combusted in the boiler is considered, and the water can be heated to about 70 ℃ after the recycling.
Step 1: the total energy used throughout the year is converted, and the total energy of the standard coal is calculated. And then counting the electric energy and the natural gas used all the year round, and counting how much standard coal can be provided by the electric energy and the natural gas used all the year round.
Step 2: after passing through the unified unit, an ant colony algorithm is utilized according to the efficiency, loss and expected cost of electric energy and natural gas (such as the electricity charge carries out step electricity price, the natural gas charge reduces price along with the penetration of a Yunnan and Burm gas pipeline, pollution discharge cost caused by burning natural gas and the like), f (Xmin) is established by taking cost as an objective function, and the global optimal solution for reasonably using the energy is searched, so that the situation that the prior consideration is incomplete and only the local optimal situation is obtained is avoided.
Constraint conditions need to be considered in an ant colony algorithm, and constraint conditions are formulated based on the boiler gas yield, transformer load and the like of the factory;
Natural gas constraint conditions:
Hmin≤Hgas≤Hmax，
Hmin minimum gas production
Hmax maximum gas production
Electric energy constraint conditions:
Hmin≤Hele≤Hmax
Hmin minimum transformer load
Hmax maximum transformer load.
In a specific embodiment, in the step 2, the step electricity price is realized by the local electricity price, and the more electricity is used in winter, the more expensive is. The heat loss is considered when the steam is used, heat loss and the like are caused by overlong steam pipelines, and the natural gas is burnt too much to cause the potential exceeding risk of annual pollution discharge NOX (nitrogen oxide) discharge. The ant colony algorithm is used for searching the global optimal solution by combining a plurality of factors, and the use of natural gas and electric energy is reasonably arranged.
And step 3, obtaining distributed energy supply according to the calculation result. The overall calculation of natural gas and electric energy used throughout the year has a plurality of devices which can use steam (obtained by consuming natural gas) and electric energy, for example, a refrigerator is divided into a steam refrigerator and an electric refrigerator, and also can heat, and can use steam and electric energy. And according to the optimal combination calculated before, the energy distribution is carried out on equipment which can use natural gas or electric energy. It should be noted that this can have a better guiding meaning for purchasing a new device.
In one embodiment, data collection is performed and all wasted and recoverable places are searched, the air compressor waste heat and the flue gas after the boiler burns natural gas are recovered, and the recovered heating water can be heated to about 70 ℃.
And step 4, outputting energy steps and performing intelligent management.
In a specific embodiment, after the energy supply mode is distributed, attention is paid to energy steps, such as silk making equipment and the like, heat contained in steam is used, condensate water of the steam still has high latent heat, steam pressure is high, and the steam requirement of an air conditioner can be completely met, so that a set of energy supply system for reasonably utilizing energy sources and greatly reducing waste and consumption is established through carding of a distributed energy supply idea.
And recycling the waste heat of the high-grade energy according to the energy cascade division, and utilizing the waste heat according to the situation. (for example, after the vapor for vacuum moisture regaining of the silk making, the vapor for the front section and the rear section, more waste heat in the condensed water is recovered, and the silk-making vacuum moisture regaining vapor is used for air conditioning equipment, canteens and bathrooms through a flash evaporation process).
