微机保护硬件发展研究

Development of Microprocessor Based Protection Hardware

继电保护的研究是电力科研的重要领域,从1950年至今历经了从最初的机电式到微机式的跨越式发展。微机保护装置之所以会大规模使用,是因为它通过强大的计算能力、逻辑判断能力以及存储记忆功能可以实现基于复杂保护原理的保护,已成为继电保护装置的主要形式。微机保护硬件结合计算机、网络以及电子技术的发展,使其性能也得到了进一步提升,并沿着智能化、网络化及保护、测量、控制数据一体化的方向不断前进。

The research of relay protection is an important field of electric power research.From 1950 on,it has experienced a leap forward development from the initial electromechanical to microcomputer.The reason why microprocessor-based protection devices are widely used is that microprocessor-based protection based on complex protection principle can be realized by powerful calculation ability,logic judgment ability and memory function.Microcomputer protection has become the main form of relay protection device.With the development of computer,network and electronic technology,the performance of microprocessor-based protection has been further improved.It is advancing in the direction of intelligence,networking and integration of protection,measurement and control data.
