【摘要】：随着社会经济的发展和能源需求量的增加,能源、环境、发展已成为当今人类所面临的三大主题。能源的合理开发与利用将直接影响环境的保护和人类的可持续发展。因此在经济发展的同时,逐步改善能源结构,发展洁净能源是亟待解决的。本文首先综述了国内外分布式能源、天然气发电、燃气轮机联合循环以及热电联产等方面的发展和研究概况,接着介绍了以天然气为燃料的分布式燃气轮机联合循环热电联产系统的组成、工作原理和财务评价、盈亏平衡分析和敏感性分析等理论以及符合预测法等基本原则、内容和方法；然后用负荷预测法预测了金东区域未来几年的负荷及电量增长情况,从地方经济发展、电力电量平衡、区域供热用户数及用热负荷趋势等多角度剖析建设金东燃气轮机热电联产项目的必要性。在深刻剖析中国环境污染及节能减排的现状和面临的形势与任务后,从提高能源利用效率、环境保护及实现可持续发展的战略高度,重点分析了该项目的经济效益和环境效益；从电网安全可靠供电的角度,结合金东电网实际,认真分析了该项目在能源的多样性、电网的安全性、电网黑启动以及调峰等方面的作用和效益。最后得出,高负荷增长下建设分布式燃气轮机联合循环热电联产项目不仅具有占地小、建设周期短、发电效率高、实现能源梯级利用等诸多优点,而且也是提高能源的利用效率,节约能源、保护环境的必然要求。
[Abstract]:With the development of social economy and the increase of energy demand, energy, environment and development have become the three major themes facing human beings.The rational development and utilization of energy will directly affect the protection of the environment and the sustainable development of human beings.Therefore, at the same time of economic development, gradually improve the energy structure, clean energy development is urgent to be solved.In this paper, the development and research of distributed energy, natural gas generation, combined cycle of gas turbine and cogeneration of heat and power are reviewed.Then it introduces the composition, working principle and financial evaluation of distributed gas turbine combined cycle cogeneration system based on natural gas, the theory of break-even analysis and sensitivity analysis, as well as the basic principles of the prediction method.Content and methods; then the load and electricity growth in Jindong District in the next few years is predicted by using the load forecasting method. From the local economic development, the electric power balance is also predicted.The necessity of building Jindong gas turbine cogeneration project is analyzed from several angles, such as the number of district heating users and the trend of heat load.After deeply analyzing the current situation of environmental pollution, energy saving and emission reduction in China, the paper analyzes the economic and environmental benefits of the project from the strategic height of improving energy utilization efficiency, environmental protection and realizing sustainable development.From the point of view of safe and reliable power supply and combining with the actual situation of Jindong Power Grid, this paper analyzes the functions and benefits of the project in such aspects as the diversity of energy sources, the security of power grid, the black-start of power grid and peak shaving.Finally, it is concluded that the construction of distributed gas turbine combined cycle cogeneration project not only has many advantages, such as small occupation, short construction period, high power generation efficiency, but also realizes energy cascade utilization.Moreover, it is necessary to improve the efficiency of energy use, save energy and protect the environment.
