基于BPA的某地区电网35kV并网线继电保护配置方案设计毕业论文

基于BPA继电保护装置属于二次系统，它是电力系统的一个重要组成部分，它对电力系统安全稳定运行起着极其重要的作用，没有基于BPA继电保护的电力系统是不能运行的。基于BPA继电保护要达到及时切除故障，保证电力系统安全稳定运行的目的，需要进行多方面的工作，包括设计、制造、安装、整定计算、调试、运行、维护等，基于BPA继电保护整定是其中极其重要的一项工作。

本次设计的主要内容是基于BPA的某地区电网35kV并网线基于BPA继电保护配置与整定设计。设计内容包括：第一章 概论；第二章 计算系统中各主要元件的参数；第三章 电力网短路电流的计算；第四章 电力变压器保护的整定计算；第五章 线路保护的整定计算；第六章 电容器的整定计算。

Abstract

Protection devices belong to the secondary system, which is an important part of the power system to power system safe and stable operation plays an extremely important role, and there is no relay protection of power system can not run. Relay to achieve the timely removal of the failure to ensure that the purpose of safe and stable operation of the power system, the need for a wide range of work, including the design, manufacture, installation, tuning, commissioning, operation, maintenance, relay protection setting is extremely important a work.

The design of the main content is based on a region of the BPA grid 35kV grid line relay protection setting design. Design elements include: Chapter 1 Introduction; major component parameters in the second chapter of the computing system; Chapter power grid short-circuit current calculation; Chapter power transformer protection setting calculation; Chapter line protection setting calculation; six chapters capacitor setting calculation.
