The Research Of The 220kV Traditional Transformer Substation Integration-automation's Use

In recent years, with the development of China's power industry, as well as the progress of computers, communications and other tecnologies, transformer substation automation system has entered a practical stage.The systerm enable the equipment (including intelligent relay-protection units and automatic device, observe and control, DC systems etc.) to exchange and deal with the data with the mainframe by using computers and network. It's a kind of full-digital and strongly-maneuverability synthesizes Automation System. As one kind of electric technical ways to improve the quality of products, it guarantees the electric power manufacture high-quality and high-efficiency.Based on the cognition of the integrated automation system, the paper consulted some kinds of the domestic substation automation system structures and also drawing on some of their advantages, particularly for interval, layered distributed integrated automation systerm structure pattern. It optimized 220kv Lu'an transformer substation automation alteration and suggested a feasible project. As a example, it shows how to use transformer substation automation systerm in the 200kv traditional transformer substation fields.The Paper present the concept of the Substation Automation System, also discussed the content, function, requirement and the design of 220kV integrated automatization system. Finally, it emphasized the alteration of the 220kv traditional transformer substation based on RCS-9700 integrated automatization system.
