Discussion on Relay Protection and Automation System ofIntelligent Substation

In the process of social development, the field of electric power engineering in my country is stilldeveloping. In recent years, many cutting-edge technologies and processes have emerged in the fieldof electric power engineering in China, which further promotes the development of electric powerengineering and gradually improves its functions. In the context of informatization, informatizationplanning and intelligent development are the key development plans of various industries at this stage,especially the emergence and application of intelligent technology has added opportunities fortransformation and development to many industries. The field of engineering projects is still trying touse intelligent technology to improve the automation of power systems. At this stage, the effectiveintegration of intelligent technology and substation has been realized, and the emergence of intelligentsubstation has further strengthened the actual effect of power system operation. In order to ensure theeffective operation of smart substations, relay protection devices and automation technologies must beused. Only with the help of this system can the important role of smart substations be fully utilized.This paper conducts a comprehensive analysis and research on this, and puts forward some insights,hoping to provide useful reference value for relevant staff.
