本科毕业设计说明书 煤矿110kV变电所副井保护系统设计 110kv coal Mine transformer substation auxiliary shaft protection system design 学院（部）： 电气与信息工程学院 专业班级： 电气工程及其自动化08-6班 学生姓名： 邱国强 指导教师： 杨岸 副教授 2012 年 5 月 25 日 副井保护系统设计 摘要 本次毕业设计是有关变电所变配电设计和变电所监控系统微机保护系统方面的内容。其中，变配电设计部分以淮南潘三矿为对象进行了配电选型计算和相关继电保护的计算。对主要设备如主变压器，架空线路，母线和开关柜进行了选型计算及校验，微机保护部分的设计选用PLC进行硬件系统配置和软件的设计。 本论文介绍了矿井提升机及其继电保护保护装置，指出了矿井提升机继电保护装置的必要性。然后介绍了继电保护的原理，再结合实际情况，提出了一套运用PLC技术来设计矿井提升机综合继电保护装置的方案。该套综合后备保护装置的原理为:通过采集各种信号，由软件程序进行处理，并判断是否动作及报警，处理后的数据用于显示和存储查询。 文中着重继电保护装置的硬件和软件设计进行了分析和说明，其中软件设计是该装置的控制部分，硬件是该装置的执行部分。另外给出了硬件的组成图及程序框图和程序流程图。 关键字：继电保护，PLC，微机监控 110kv coal Mine transformer substation auxiliary shaft protection system design ABSTRACT The graduation project is about changing power distribution substation transformer substation monitoring system design and microprocessor-based protection systems content. Among them, the part of distribution design change to the 3rd Mine of Pan,Huai-nan Mining Industry,the distribution for the selection of subjects related to computing and the calculation of relay protection. Major equipment such as main transformers, incoming lines, bus bar and switchgear for the selection of calculation and check.The part of microprocessor-based protection system design,selected PLC hardware system configuration and software design.  This paper introduces the auxiliary shaft hoist and its protective relaying protection device .The paper points out that mine hoist relay protection device is necessary .Then it introduces the principle of relay protection, combined with the actual situation, proposed a set of using single chip computer technology to the design of mine hoister synthetic protection device for. The integrated backup protective devices principle is: through the acquisition of a variety of signals, a software program for treatment, and determine whether the action and alarm, the processed data is displayed an
