发电厂电气主接线设计作者:卢平摘要随着我国经济得不断进展,对电得需求也越来越大。电力工业就是我国经济进展中最为重要得一种能源,主要就是它可以方便、高效地转换其它能源形式。电力工业作为一种先进得生产力,就是国民经济进展中最重要得基础能源产业。而火力发电就是电力工业进展中得主力军。截止 2025 年底,火电发电量达到 48405 万千瓦,约占总容量得 77、82%。由此可见,火力发电在我国这个进展中国家得国民经济中得重要性。本次设计就是针对 2*300MW 火力发电厂电气部分得设计,电气主接线就是发电厂、变电站电气设计得首要部分,也就是构成电力系统得主要环节。所以本次设计电气部分主接线方案为一台半断路器接线。该设计主要从理论上在电气主接线设计、短路电流计算、电气设备得选择、配电装置得布局、防雷设计、发电机、变压器与母线得继电保护等方面做详尽得论述,同时,在保证设计可靠性得前提下,还要兼顾经济型与灵活性,通过计算论证火电厂实际设计得合理性与经济型。采纳软件绘制电气图与查阅相关书籍,进一步完善了设计。关键词:电气主接线;短路电流;配电装置;电气设备选择AbstractAs China's economic development,the demand for electricity is growing。Electric power industry in China's economic development is one of the most important energy,mainly it can be easily and efficiently convert other forms of energy 。As an advanced productivity in the electrical industry,is the most important foundation in the development of energy industry of the national economy。Thermal power is the main force in the development of the electric power industry。By the end of 2025, thermal power generating capacity reached 484、05 millionkilowatt,77、82% per cent of total capacity。Thus,thermal power generation in China,the importance of developing the national economy。This design is designed for electrical parts of the 2*300MW thermal power plant,main electrical connection is the primary part of the electric design of power plant and substation,constitute the main part of power system。 Design of main electrical connectio...
