供电工程课程设计 题 目 某机械制造厂供配电设计 学 院 自动化与电气工程学院 专 业 电气工程及其自动化 班 级 电气094 学 号 109032106 学生姓名 朱胤炜 指导教师 刘峰 完成日期 2012年6月28日 摘 要 随着科技的进步和工业生产的发展，工厂供电已经越来越得到人们的关注和重视。电能作为当今世界的最主要环保能源之一，也是现在社会发展的最主要能源之一。而工厂供电是企业生产生活的的必要保障，更是一个国家发展和壮大的根本命脉。所以，为了让我们更好的了解和懂得供电工程这门课程，以及对供电系统、继电保护和电力系统等有一个更加深刻的了解，老师给我们指定了以“某机械制造厂供配电设计”为题目的供电工程设计。 为此，我们以自己在课堂上学习的《供电工程》内容为基础，辅以《电力系统继电保护雨里及应用》的保护整定以及《电力系统分析》的部分知识，对该课程设计经行了负荷计算、无功补偿计算、短路电流计算，进行自主的变压器的选择，从可靠、安全、经济等方面对断路器、供电线进行了选择，从供电的的优质、可靠、经济等性能来进行综合考虑，采用最优化的电气设备和供电方式。 关键词： Abstract With the progress of science and technology and the development of industrial production, the factory has been more and more get the power supply people concerned. As the worlds most power main environmental energy, and also one of the main social development is now one of the energy. And the power supply enterprise production factory is the life of the necessary security, but also a national development and growth of the fundamental lifeblood. So, in order to make us better understand and know the power supply project this course, and for power supply system, relay protection and power system have a more profound understanding of, the teacher gave us a designated as a mechanical factory for distribution design in the subject power supply engineering design. For this reason, we in their own learning in the classroom the power supply project content as the foundation, with the power system protection in the rain and application protection setting and the electric power system analysis, part of the knowledge, the course design of the line the load calculation, reactive power compensation calculation, short-circuit current calculation, the transformer independently of choice, from reliable, safe, economic and other aspects of circuit breaker, power supply line on the choice, from the power supply of high quality, reliable,
