Abstract Substation integrated automation system in substation application automatic control and information processing and transmission technology, through the computer hardware system instead of manual or automatic device of operation, improve the management level of substation operation, through automation, substation automation system devices in the mutual exchange of information, data sharing, the completion of substation operation monitoring and control task. Substation integrated automation system is to improve the level of safe and stable operation, reduce operation and maintenance costs, improve economic efficiency to provide users with high-quality power is an important technical measure. Function integrated is its biggest characteristics is different from conventional substation, it is based on computer technology, In data communications as a means, to information sharing as the goal, through the transformer substation the original protection, instrumentation, central signal, remote devices such as the two times system and function of recombined, Internet and computer, set of substation protection, measurement, monitoring and remote control in one, completely replace the conventional substation two equipment, simplifying the the two wiring of transformer substation. Integrated substation automation system has the following advantages: (1) improve the quality of power supply, improve the voltage qualification rate. (2) the improvement of safety, reliable operation level. (3) improve the operation of power system, the management level. (4) narrowing of substation area, reduce cost, reduce the total investment.(5) reduce the maintenance workload, reduce the attendant labor, implementation decreases person synergism.
Key words: automatic control technology; information processing; data sharing
