1、机加厂房配电系统设计-I-机加厂房配电系统设计摘要随着社会不断发展，电力系统在我国工业生产和日常生活中得到广泛应用。众所周知，电能是现代工业生产的主要能源和动力，无论是从经济发展还是社会生活方面来说，电力已迅速成为重要能源之一，因此对电力系统的研究也日益重要。电能作为最广泛使用的能[1]源之一，是因为它在生产、传输、分配、转换、控制和管理等方面都非常便易。因此对用户的供电能力是电力系统的重要环节，供电的可靠性及功率损耗也值得重视。电能在工业生产中的重要性，在于工业生产实现电气化以后可以大大增加产量，提高产品质量

2、和劳动生产率，降低生产成本，减轻工人的劳动强度，有利于实现生产过程自动化。从另一方面来说，如果工厂的电能供应突然中断，则对工业生产可能造成严重的后果。因此，做好工厂供电工作对于发展工业生产，实现工业现代化，具有十分重要的意义。而在电力系统规划和设计时则需要考虑一些因素，首先保证电力系统运行的安全可靠性；其次是保证良好的电能质量；再次是保证系统运行的经济性。继电保护是保证电力系统安全运行和提高电能质量的重要环节，在设计电力系统时要对输电线路进行继电保护，进行相关环节的计算。因此对配电线路的设计和计算具有重要的现实

3、意义与工程价值。本论文以某机械制造厂为研究对象，探讨了厂区配电线路的设计方案。首先对研究对象的基础资料进行调查研究，掌握设计方案的背景。进而对其供电的配电线路进行负荷计算和线路短路计算，选择符合研究内容要求的电气设备，同时考虑了其外部保护的方案措施。关键词：电力系统；供电；配电线路；短路计算；继电保护-II-机加厂房配电系统设计目录第1章绪论······················································································
