【摘要】 继电保护装置的作用,是当电力系统中电气元件或设备发生故障时将故障元件从电力系统中切除,使故障元件免遭更大破坏,并使电力系统尽快恢复正常运行。继电保护测试是在运行前和检修期间对继电保护装置进行检查的重要设备,对它们的深入研究对尽早检测保护装置的故障,保证电力系统安全稳定的运行有着重要的意义。继电保护测试装置通过输出交流三相电压、电流来模拟电力系统中的各种故障,并测试继电保护及安全自动装置当故障发生时对故障的响应状态和响应速度。RT-DSP继电保护微机试验装置课题,是在电力系统对继电保护测试装置技术要求不断提高的背景下提出的。本文主要研究对象是微处理器(DSP)系统的开发,包括测试系统的构建,软硬件设计、制作和调试等。系统设计存在几个技术关键:寻求良好的系统构建方法,建立和微型机通讯的有效协议,高性能任意波形发生器的实现,继电保护装置动作的识别,故障再现的实现和装置电磁兼容性的保证等。论文通过第二章的系统设计、第三章的微处理器部分的硬件结构设计和第四章的监控测试软件,指出了微处理器系统解决以上技术关键的方法,论文最后阐述了毕业设计主要成果和系统需要进一步完善的地方。更多还原

【Abstract】 The protective relay equipment is very important for electrical power system,and protective relay test is in operation before and during the overhaul of the important equipment and protective devices, which ensure the security and stability of the electricity system functioning. According to the protective power system testing devices to upgrade the technical requirements set forth RT-DSP protective devices.The emphasis of this thesis is to develop the microprocessor system of the RT-DSP Protective Relay Test Equipment Based On Microcomputer, including the designing and debugging of hardware and software.There are several key techniques in the system of microprocessor as follows:Seeking a good structure of the system,Setting up an effective protocol between microcomputer and microprocessor,Implementing a high performance arbitrary wave generator,Creating a circuit that can identify all the actions of relay,Redisplaying fault waveform,Guarantee for electromagnetic compatibility, and so on.This thesis points out the settlements of key techniques through the instructions of chapter three and chapter four. Particularly, chapter three concerns the hardware structure of the microprocessor system, chapter four discusses the monitoring and testing software, moreover, the measures to handle the electromagnetic compatibility and anti-interference are also provided in these two chapters.更多还原
