摘要
变电站在电力系统中的地位十分重要,随着我国电力事业的发展,变电站的二次部分由传统的二次设备包括测量仪表、信号系统、继电保护、自动装置和远动装置发展为能实现对全站的主设备和输、配电线路的自动监视、测量、自动控制和微机保护以及调度通信的综合性的自动化二次系统,同时变电站的数字化和综合自动化不仅为实现变电站无人值班和配电网实现综合自动化奠定了基础,而且也为供电部门提供更加安全、经济可靠和高质量的电能创造了条件。
本设计主要是对110kV变电站一次部分进行相应的继电保护设计和二次回路初步设计。结合所学各科知识和根据参考标准完成设计。本设计主要包括以下内容:第一章,绪论;第二章,110kV变电站电气一次部分的基本情况;第三章,变电站主变压器的保护方案设计;第四章,变电站母线的保护方案设计;第五章,变电站输电线路的保护方案设计;第六章,断路器和隔离开关控制回路的设计;第七章,互感器的配置和接线设计;第八章,变电站信号回路和其他二次部分的初步设计;第九章,微机保护的整定计算。

Abstract
The status of substation in power system is very important, as our country the development of the electric power industry, the second part by the traditional substation of secondary devices include measuring instrument, signal system, relay protection and automation and far micromovement device for can realize the development of the main equipment and total defeated, the automatic monitoring, power distribution lines measuring, automatic control and puter protection and prehensive automation quadratic system while substation digitization and integrated automation not only for realizing substation nobody on-duty and work to prehensive automation, but also laid a foundation for the power supply departments to provide more security, economic reliable and high quality power created the conditions.
This design is mainly to a part of 110 kV substations make corresponding relay protection design and secondary circuits preliminary design. Unifies studies various branches knowledge plete design according to the reference standard. This design includes the following content: Chapter 1, introduction. Chapter 2, 110 kV substations, the basic situation of electric is a part. Chapter 3, the main transformer substations protection scheme design. Chapter 4, busbar protection substation project design. Chapter 5, substation transmission line protection scheme design. Chapter 6, breaker and isolating switch control circuit design. Chapter 7, transformer configuration and wiring design. Chapter 8, su
