毕业设计说明书中文摘要分布式发电指的是规模不大、分布在负荷或者配电网附近的发电单元，具有经济、可靠和高效的特点。分布式能源系统就是将清洁能源按照用户需求供应能量。它可以具有一种或者多种功能，可以只提供一种或者多种能源[1]。分布式能源系统在国外发达国家使用广泛，在国内处于快速发展阶段。本文将介绍三种分布式能源利用系统，并介绍国内外这三种能源利用系统的现状和国内对于这三种分布式能源利用系统的相关政策。并进行一些市场调研，最终在RETScreen软件上对着三个能源利用系统分别进行设计和经济性分析，分析它们的收益与环保效益，思考它们盈亏的决定性因素和投资前景。最后分别对他们进行建模仿真，观察它们的仿真结果。84182

Title    Based on the RETSCREEN distributed energy system    design and evaluation                 

Abstract

Distributed generation refers to by small size, distribution near the load or the distribution network of power generation facilities to achieve economic, efficient and reliable power generation unit。 Distributed energy system is to supply energy clean energy according to user requirements。 He can have one or more functions that can only provide one or more energy。 Distributed energy system is widely used in foreign developed countries, in a stage of rapid development in China。 , this article introduces three kinds of distributed energy system at home and abroad and introduces the three kinds of the status quo of energy utilization system and domestic for the three kinds of distributed energy system of relevant policies。 And do some market research, and finally on the RETScreen software to three energy systems for design, and economy analysis, analysis of their benefits and environmental benefits, thinking they are the decisive factor of profit and loss and investment prospects。 The modeling simulation to them respectively, observe their simulation results。
