1、 论文题目：煤矿供电系统面保护技术的研究与实现 专 业：电气工程及其自动化 摘 要 电力系统是煤矿生产的重要组成部分。由于煤矿井下环境较为特殊，通过提高煤矿 供电和系统运行的可靠性来保证煤矿生产的正常运行及安全。 煤矿现有的继电保护系统基本都是点保护，本次设计采用面保护技术，使设备能综 合自身及其它开关点信息来做出故障判断和动作出口，它不需要靠延时来实现动作配 合，这对煤矿供电继电保护系统以及煤矿的安全正常生产具有重要的意义。 本设计包括测控单元、通信单元和上位机监控单元。测控单元采用 DSP TMS320F2812 及单片机 STC89C52RC 为处理器，通信方式采用 CAN 通信模式，上

2、位 机监控采用力控 6.1。 关键词 :面保护,测控单元,通信单元,上位机监控 Subject: Research and Implementation of the supply system about area-protection technology in underground coal mines Specialty: Electric Engineering and its Automation Name: Hao Chunyang (Signature) Instructor: Lu Jianqiu (Signature) ABSTRACT Electricity is th

3、e main energy production of coal mining enterprises. Due to the underground environment of coal mine is special, In order to minimize the power supply problems which the damage caused by personnel equipment for coal mine and the influence of the normal, We need set out to coal mine enterprise power

4、supply and power supply coal mine relay protection system through two aspects to ensure the safety of coal mine personnel equipment and normal production activities. Production Coal mine of existing relay protection system is the basic point protection .That is, all protection equipment only base on

5、 switch points where there is fault information to complete their protection task. The protection based on communication makes the equipment synthesize own and other switch points and make fault information judgment and action exports. It does not need to rely on delay to implement actions. The powe

6、r supply of coal mine relay protection system and the normal production of coal mine safety is of great significance. This design includes ensure and control unit, communication cell and PC monitoring unit. Measurement and control unit uses the digital signal processor TMS320F2812 and single chip microcomputer as the processor STC89C52RC.communication mode, adopting CAN communication mode, PC monitor units uses force control with 6.1 as the main interface, and
