Analysis And Research On Access System Of Waste Heat Power Generation Projects In Iron And Steel Enterprises

Energy is not only the material basis for human society,but also the necessary condition for competitive development of all countries.The iron and steel industry plays an important role in the energy consumption of our country,which plays a very important role in people's daily life and provides guarantee for the economic development of our country.Although our country is a big country of iron and steel industry,but in the process of producing iron and steel,there will be a lot of waste heat.If the waste heat is not reused,it will waste a lot of energy,so the iron and steel industry is a very high energy consuming industry.At present,more and more iron and steel enterprises will collect and reuse the exhaust gas,so as to use the exhaust gas as the secondary energy for power generation.However,many iron and steel enterprises use the waste heat produced by iron and steel smelting with low efficiency,less electricity produced,and waste a lot of resources.Therefore,how to effectively use the waste heat of iron and steel enterprises for power generation,successfully connect the waste heat power generation project of iron and steel enterprises to the power grid,improve the power supply quality of the power system,and further alleviate the power supply pressure during the peak period of power consumption is the purpose of the waste heat power generation of iron and steel enterprises.Optimal power flow(OPF)can help the power system to solve the problems of power dispatching,transmission capacity and powerdistribution.The essence of OPF analysis is to solve the nonlinear problems with multiple variables and constraints,which has the advantage of solving the optimal value.Therefore,this paper takes the access system of the waste heat power generation project in iron and steel enterprises as the research subject.Through the optimal power flow calculation and simulation based on the artificial bee colony algorithm,the superiority of the algorithm is obtained.And the access scheme of the waste heat power generation project in iron and steel enterprises is designed with the actual case,which provides the most appropriate scheme for relieving the pressure of the power system.In this paper,firstly,the research situation of waste heat power generation in iron and steel enterprises at home and abroad is reviewed,and the importance of waste heat power generation to environmental protection is clarified.Secondly,the waste heat power generation system in iron and steel enterprises is described,the methods and equipment of waste heat power generation are analyzed,and the technical characteristics of converter waste heat power generation are summarized,which lays a foundation for the research of this paper.Combined with the characteristics of power system access,the mathematical model of the artificial bee colony algorithm is established,and the process and steps of solving the optimal value of the artificial bee colony algorithm are analyzed in detail.The simulation of the artificial bee colony algorithm is carried out,and the calculation optimization performance of the artificial bee colony algorithm is obtained.Based on the artificial bee colony algorithm,the optimal power flow problem of the power system is studied,and the optimal power flow problem is established Based on the mathematical model of optimal power flow,the optimal power flow ofthe artificial bee colony algorithm is simulated and analyzed,and the optimal value of the algorithm is obtained.Finally,through the load forecasting of power and electricity in Wuzhou City,combined with the optimal power flow algorithm,the access scheme of steel waste heat power generation project is designed,and the most appropriate scheme is selected through calculation.
