The Microprocessor System Design Of RT-DSP Protective Relay Test Equipment

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.
