微机保护实验装置组态软件的开发

his paper analyzes the study and development of the experiments of teaching for digital relaying protection on abroad and home.Based on the requirement of experiments of teaching for digital relaying protection in home colleges.The configuration software of experimental device for digital relaying protection is developed.The frame of configuration software is true of the identical Single Chip Microcomputer and different Single Chip Microcomputer. The configuration software is divided into PC software and Single Chip Microcomputer software.The modularization design idea is adopted in this paper.The PC software is chiefly for setting-up control system of hardware and selecting algorithms and protections and setting-up the setting values.The PC software can also communicate with the digital relaying protection device by the RS232 interface or USB interface.The Single Chip Microcomputer software can carry out the read analogue input function,measurement function,switching input function,controlling output function,protection function,local setting and displaying function and communication function.Students hold the principle,design of hardware and software and algorithm analysis of digital relaying protection by simulating instructional experiments.Experiments indicate that the configuration software can reach expected effect.
