ABSTRACT:With China's science and technology development, especially computer technology progress of the transformer substation, power system more requirements for more and more is also high. 

　　Microcomputer relay protection device type in the power system has been widely used. Compared with conventional protections, microcomputer protection with advanced principle and structure, installation simple operation and maintenance convenience, protect sensitive and reliable and quickness can automatically record fault information and other significant advantages. In this paper the microcomputer relay protection, illustrates the feature and advantage of microcomputer protection, and the algorithm and made mainly discusses anti-interference measures. 

　　With the rapid development of electric power system and computer technology, communication technology progress, relay protection technology faces further development trend. The relay protection technology at home and abroad for: the development trend of computerized, networking, protection, control, measurement, data communications integration and artificially intelligent, it put forward to relay protection workers difficult task, also pioneered the wide space activities. 

　　The microcomputer relay protection, development process, summarizes the microcomputer relay protection technology achievements, this paper puts forward the future development trend of relay protection technology is: network, protection, control, measurement, data communications integration.
