With technological advances, the traditional relay protection devices are gradually being replaced by microprocessorbased protection. Microprocessorbased protection is referred to as the protection of PC puter, a digital relay protection, is based on the programmable digital circuit technology and realtime digital signal processing technology of the Power System Protection. At present, both at home and abroad have been developed to 32bit digital signal processor for hardwarebased protection, control, measurement, and data munications integration of microprocessorbased protection control devices, and artificial intelligence technology into a number of relay protection, such as artificial neural works, fuzzy theory to determine the realization of fault type, fault location, the direction of protection, the main equipment and other new methods of protection. By means of wavelet analysis of the theory of digital signal failure of the entire frequency band information and to achieve fault detection. These artificial intelligence technology to improve the accuracy of failure to provide a means of identification, but also some singlefrequency signal based on the traditional method difficult to identify the problems to be resolved. At present, the microprocessorbased relay protection is along the microprocessorbased protection work, and intelligent, adaptive and protection, control, measurement, signal, data munications integration direction. 譯文： 變電站是電力系統(tǒng)中不可缺少的重要組成部分，它擔負著電能轉換和分配的任務，對電網(wǎng)的安全和經濟運行起著舉足輕重的作用， 是聯(lián)系發(fā)電廠和用戶的中間環(huán)節(jié) 。s power plants and intermediate links. With economic development, expanding grid capacity, reliability of operation of the power grid is getting higher and higher requirements. Development of science and technology, intelligent switches, photoelectric current and voltage transformer, a runline state detection, training simulation Substation Operation matures, such as hightech, as well as fiberoptic technology, puter highspeed work system in the development of realtime applications, bound to the existing substation automation technology have a profound impact, alldigital substation automation system development trend. Keywords: substation automation Power system is operated by the production, transmission, distribution and consumption of a variety of power linked to the position of electrical equipment. As a result of a large number of power can not be stored, we must ensure that the production of electricity and energy balance. With the scientific and technological advances in the technological development of our country has reached a certain level. Intelligent switches, photoelectric current and voltage transformer, a runline state detection, training simulation Substation Operation matures, such as hightech, as well as fiberoptic technology, puter highspeed work system in the development of realtime applications, significantly increase the transformation degree of automation. Design of our substation substation cable programs tend to be simple, many of the recent domestic new 220 k V substation and 110kV voltage levels of wiring without the use of dualbus bypass bus. The use of GIS, the priority subbus single wire. Terminal Substation, the line as far as possible, such as transformer unit wiring. A large number of the introduction of new technology, transformer substation rising level of electrical equipment, power distribution devices from the traditional form of moving toward oilfree, vacuum switches, SF6 switches and mechanical, electrical equipment bination of the development of smallscale integration. In recent years the world famous highvoltage electrical equipment panies have been developing, the development of the various types of 145550 kV outdoor highpr
