According to transformer substation monitoring requirements, 110kV substation automation system is for design. And the study is summarized as the follow steps．First of all, covers domestic and foreign development of substation automation, purpose and significance of the research on substation automation, brings out the design of substation automation system. Secondly, according to the Sourcebook of substation and monitoring requirements, and substation automation system design principles, research and design the automation system’s structure and function. Third, according to the original data, integrating principles of substation design and national laws and regulations, systems, and the substation monitoring requirements, design the main circuit wiring of substation; simple calculations to select the basic equipment of substation load. Fourth, outline the operation process of PLC and design the PLC control system; according to the importance of high-voltage circuit breaker control and PLC control circuit breaker’s advantage, design using PLC control to high voltage circuit breaker; based on the importance of integrated bus coupling spare switching and operational processes, design the PLC control system of automatic bus transfer system. Finally, draw a conclusion of the papers design and design process, sum up the problems and defects in design, and where to work toward.
