| Energy and environmental issues have been a major issue for my country over the years and a major global challenge.From the strategic point of view of sustainable development,we must maintain the harmonious development relationship between ecological balance,environmental protection and economic construction,so how to develop and effectively use clean energy has far-reaching strategic significance for the sustainable development of our economy and environment.In this study,distributed power supply is applied to a central heating system in Panjin.The "low cost" and "high flexibility" of distributed power supply are used as the starting point.At the same time,the decentralized equipment resources in distributed power supply system and central heating system are integrated to maximize the utilization efficiency of equipment.The main work and results of this study are as follows:(1)Electrical energy generating equipment consisting of photovoltaic cells is selected to form a distributed power supply system.The electrical energy generated is directly converted into heat energy through resistance,and heat exchange occurs with the heat circulation carrier at the designated position in the central heating system.Complete the combination of distributed power supply system and central heating system.(2)Based on the analysis of the electrical characteristics of the key equipment,the software and hardware platform is designed and built,and an effective control method is put forward.The driving control system realizes the functions of collecting and accumulating analog signals and automatically tracking the maximum power output points of photovoltaic cells according to the predetermined mode.(3)Integration of decentralized equipment resources,establishment of a remote monitoring platform,real-time monitoring and preservation of the operating data of distributed power supply systems and heat exchange station systems for central heating,and custom generation of historical reports and trend curves,so as to do a good job of basic work for the statistics and analysis of operational data.(4)According to the stage characteristic of the heat energy demand of the user,the operation scheme of central heating is optimized and reformed,and the energy saving subroutine is added to realize the rational distribution of heat energy without increasing the investment of equipment funds.The application of distributed power supply in central heating system in this paper reduces the consumption of fossil energy in the production of heating enterprises and reduces environmental pollution.The auxiliary heating system also provides a new solution for DC distribution and local absorption of distributed power supply. |
