The paper is designed for electric power and is divided into five chapters, with the second and third chapters about low voltage distribution and the fourth and fifth chapters about site design. The paper mainly covers topics on low voltage distribution system, short circuit current computation, equipment selection and calibration, overcurrent protection setting, overvoltage protection setting, substation and distribution station designing, household distribution design, design for public part of the lightening and its control in residential building, design for lightening protection system etc. The graduating design for the electrical system in the residential building aims to apply the theoretical knowledge from class and put it into practice. Through the practical designing process, the regular approaches and methods for electrical design in buildings can be better grasped and the engineering problems can be analyzed and solved. It lays a strong foundation for a career in electrical designing in the future. Key words：Electrical design, Electric power supply and distribution system, Lighting, Lightning protection  目 录 中文摘要 Ⅰ ABSTRACT Ⅱ 1绪论 1 1.1课题意义 1 1.2课题基本情况 1 1.3外部条件 2 2低压配电系统设计 3 2.1变配电所选址及符合等级 3 2.1.1配电
