精品文档---下载后可任意编辑 本次设计的主要内容是变电所的主变压器的选择、主接线的选择、短路计算、变电所保护装置等的选定进行设计，通过对变压器以及线路保护配置的选择，来保证电力系统的安全运行。其主要采纳的保护有继电保护、过电压保护、瓦斯保护、变压器差动保护。 本次设计是我们在校期间进行的最后一个非常重要的综合性实践教学环节，也是我们学生全面运用所学基础理论、专业知识对实际问题进行设计（或讨论）的综合性训练，同时还是我们将来走向工作岗位而奠定的基本实践。通过本次设计可以增强我们运用所学知识解释实际问题的能力和创新能力，以便更好地适应工作的需要。 电力系统继电保护的设计与配置是否合理，直接影响电力系统的安全运行，故选择保护方式时，满足继电保护的基本要求。选择保护方式和正确的计算，以保证电力系统的安全运行。关键词 电力系统，继电保护，整定计算，灵敏度校验AbstractThis important task of this design is protective relaying design of sabstation through the pootective distribution of the tramsformer and lines. Ensure the Electric power system’s safe operation.Mainly uses the protection has the gas to protect, the transformer differential motion protection, the electric current, the load, the distance protection. This design is we in school period carries on last the count for much comprehensive practice teaching link, also is our student comprehensively utilizes studies the basic theory, the specialized knowledge carry on the design to the actual problem (or research) the comprehensive training, simultaneously or we future will move towards the basic practice which the work post will establish. May strengthen us through this design to utilize studies the knowledge explanation actual problem the ability and the innovation ability, in order to meets the work need well. The Electric power system’s protective relaying design and distribution whether is rational directly affect safe operation whon selecting protective duty. S...
