Research on the Application of Automation Control System in Intelligent Dispatch of Substation

PAN Shuyang，ZHANG Xinyuan

[Abstract]The article takes a 220 kV substation in Shaanxi Province as an example to design an automation control system suitable for the substation and explore the application effect of the automation control system in intelligent dispatching of the substation. The research results indicate that the data delay of the fiber optic communication system in this system is lower than the design target， and the response time of the differential protection device and overcurrent protection device is better than the design requirements. Moreover， the scheduling efficiency and system operation reliability are greatly improved.

[Keywords]automation control system； substation； intelligent scheduling
