Research Of General Relay Protection Platform For Experiments

With the gradual development of China's power grid and the continuing growth of electricity demand for the social economy, the practical applications of Power system relay protection in power system is Increasingly wide-spreading, thus the requirements of relay protection apparatus are increasingly higher and higher. With the relay protection is developing in the direction of digital and information, new principles and new generation of microcomputer relay protection have generated, then put forward higher requirements on hardwares of the microcomputer protection device, at the same time, make it more difficult for learning and mastering. The rapid development of Integrated circuits and computer technology promoted more rational hardwares'structure, more perfect function, In particular, the softwares of relay protection possess reconfiguration, make it easy to realize many perfect kinds of protection principles on a common hardware platform. This paper gave an extensive analysis and research of relay protection at home and abroad, and proposed a common experimental platform for design ideas in connection with development requirements and trends of relay protection at home and abroad. This article described a general computer relay protection experiment platform which combines computer control and multimedia teaching in detail, and give a introduction to the hardware structure and implement method of this platform. The platform can finish a variety of power system protection experimental, and help the laboratory personnel get a better understanding of the protection principle, operating characteristics, hardware structure, protection algorithms, digital filter characteristics and so on. The platform both considerd the principle of openness, achieved to download compiled executable program, for the realization of the development test using the new protection principle procedures, the multimedia software provided a more convenient platform for the teaching of computer protection, it can mainly finish the teaching of computer protection hardware and the demonstrate of protection algorithms, to make the learner get a more profound study about the computer protection. In a word, the main content of this topic is how to design the software and the hardware of a general computer relay protection experiment platform, and develop a multifunction experiment system of computer relay protection which is not only combined of software and hardware but enough intelligentized.
