rough this connection mode needs manycables, and the cost is high. Besides, the information It is electric operation management or achieve deep application of Since DCS is the most important system in power ３ Feasibility Analysis of Electrical System Integrated Automation The improvement of electrical system automation is based on integrated automation and field bus or industrial Ether technology. Microputer9based protection and automation devices are widely used in power plant electrical system. The measure, logic judge, action, record and man9 machine interface function can be done by software. Moreover, all these devices have munication interface, they can exchange information with master system or with each other through field bus. Fieldbus technology has been widely used in industry and electric power field , and it has been paid more and more attention. The technology in munication rate , munication distance and anti jamming capability has been improved. Many sorts of standards have been formed, such as Profibus advocated by Siemens, FF by ABB, CAN originated from automobile industry and Lon works brought forward by Echelon pany. They are all influential fieldbus technology and applied in industry automation area [4 ]. Recently, industrial Ether work bees new hotspot. The application of microputerbased devices of electrical system, fieldbus or industrial Ether technology and munication capability provided by DCS system bring powerful support for the integrated automation of power plant electrical system. 4 Real inaction of Integrated Automation in Electrical System Electrical system integrated automation is to connect foregoing many protective relay and automation devices by fieldbus and then connect them to DCS system and (possible) electrical workstation through munication devices. The electrical workstation imple。
