中电投高培中心分布式供能系统的配置与优化
|
摘要
能源是国民经济发展的重要物质基础,世界各国都把建立可靠、安全、稳定的能源供应保障体系作为国民经济的战略问题之一。在能源供应日益紧缺的今天,合理利用能源,提高能源利用率已成为世界各国普遍关注的问题。冷热电三联产是在热电联产的基础上发展起来的,它使燃料燃烧产生的具有较高品位的热能通过汽轮机或燃气轮机等热功转换设备发电,同时利用做过功的品位较低的热能冬季向用户供热、夏季利用消耗热能的制冷机组向用户供冷。本文从实际工程中电投高培中心的分布式供能系统出发,它采用了天然气冷热电三联产系统,是一种对天然气进行梯级利用的系统,可以有效地提高一次能源利用率。
文中,首先介绍了分布式供能系统的定义、应用和特点,综述了国内外在这一领域的发展现状,接着简单介绍了本文所研究对象中电投高培中心的工程概况,从其建设分布式供能站的必要性、设计原则等入手,分析了高培中心的电力系统现状和热负荷现状,对于其电力系统现状,从接入系统方案和系统继电保护两方面进行了具体的分析和核算;根据其热负荷现状,进行了热负荷预测以及设计热负荷。其次,对于分布式供能系统中较重要部分的燃气轮机组,文中从机组选型原则、机组选型方案以及供热运行方案的确定几个方面进行了具体的阐述,并分别从总平面布置、热力系统、热工控制方法、采暖空气调节以及对环境的影响等多个因素,对于分布式供能系统的工程设想做了研究和分析。最后,文中给出了分布式供能系统的工程经济效益分析,从投资估算着手,给出了基本的财务指标、敏感性分析和热电比分析,来证明此项目具有可行性和一定的经济效益。
热电冷三联供系统由于其节能、清洁能源受到越来越多人的重视,在全国推广热电冷三联供的战略构想尤为迫切。从本文所叙述的中电投高培中心分布式供能系统来看,其研究结果对于天然气分布式供能系统的推广和应用有重要意义和一定的促进作用。
Energy resource is the important material element of the national economy development. All the countries in the world regard the building of a reliable, secure and stable energy providing system as one of the strategic problems in national economy development. Nowadays the shortage in energy resource results in high priority in rational use in energy resource and improvement in its efficiency. Combined cold, heat and power (CCHP) system is developing on the basis of combined heat and power system, which makes the heat energy generate power through steamer or gas turbine. At the same time, CCHP system uses the used heat energy to provide heat in winter and the used refrigeration equipment to provide cold in summer. This paper starts from the distributed power system in advanced training center in China Power Investment Corporation. This system is a CCHP system using natural gas as its fuel. The rundle using of natural gas can surely improve the use efficiency of the energy resource.
In the paper, it firstly introduces the definition, application and characteristic of the distributed power system. Also the development situations at home and abroad are shown in the passage. Then a brief introduction of the distributed power system in advancing training center of China Power Investment Corporation is stated on several aspects such as the necessity of building the distributed system and its design principle. The analysis on the power system status quo is calculated from the connecting system method and relay protection. From the analysis on the heat status quo, we do the heat prediction and design. Secondly, for one of the important components in the distributed power system- the gas turbine, the paper does a detailed research on its choosing principle, models definition and heat operating method. Except that, the plane collocation, choice of the system site, fuel system, heat system, the control on heat engine, the regulation of the conditioner and the environmental effect are shown in the paper to do a research and analyses on the project design. At last, the economic analysis of this distributed power system is stated. From the estimated calculation of the investment, the basic finance guideline, sensibility analyses and heat power ratio analyses are provided to prove the feasibility and benefits of the system.
Owing to the its energy-saving and clean energy resource, CCHP system is attached more and more importance. The generalized application of CCHP is urgent. The research results of the distributed power system in advanced training center of China Power Investment Corporation speed the process of generalization in the distributed power system using natural gas as the fuel.
