基于多种能源接入的冷热电三联供系统
技术领域
[0001] 本发明属于冷热电三联供系统领域,尤其是涉及一种基于多种能源接入的冷热电三联供系统。
背景技术
[0002]能源是人类赖以生存的物质基础,是经济发展的原动力,也正因为此,当今世界,在经济高速发展的同时,煤炭、石油等不可再生能源也面临着枯竭。传统电力行业以火力发电为主,消耗了大量的煤炭资源,同时也造成了严重的环境污染,资源与环境的压力给电力系统带来了新的挑战,利用新能源逐步取代传统能源进行发电将是今后电力工业发展的趋势。分布式能源系统是一种一次能源以气体燃料为主,可再生能源为辅的分布在用户端的能源综合利用系统,冷热电三联供是分布式能源的一种,具有节约能源、改善环境,增加电力供应等综合效益。而目前冷热电三联供系统主要以天然气为一次能源,综合能源利用率较低,特别是在一些偏远地区,当天然气的供应受到限制时,冷热电三联供系统不能有效地运行。
发明内容
[0003] 有鉴于此,本发明旨在提出一种基于多种能源接入的冷热电二联供系统,以提尚能源的综合利用效率。
[0004] 为达到上述目的,本发明的技术方案是这样实现的:
[0005] 基于多种能源接入的冷热电三联供系统,包括沼气,太阳能,地热能,发电系统,热交换系统以及冷热电负荷,所述沼气与直燃机,微燃机相连,所述太阳能依次连接光伏发电,电网冷热电负荷,所述地热能与发电机,热交换机相连。
[0006] 进一步的,所述直燃机与微燃机并联接入系统,直燃机为用户提供冷量与热量,微燃机与电网相连,用于发电。
[0007] 进一步的,所述发电机与热交换机并连接入系统,发电机与电网相连,利用汽轮机将机械能转化为电能用于发电,所述热交换机为用户提供冷量与热量。所述电网与电负荷,冷负荷,热负荷相连,当直燃机与热交换机提供的冷量与热量不能满足用户要求时,电网通过电力系统为用户提供量与热量。
[0008] 相对于现有技术,本发明所述的基于多种能源接入的冷热电三联供系统具有以下优势:
[0009] 本发明所述的基于多种能源接入的冷热电三联供系统可以结合区域特点利用沼气,地热等可再生能源实现沼气,太阳能,地热能的综合利用,提高能源综合利用效率,同时能够有效节约能源、改善环境,增加电力系统的综合效益。
