Abstract:With the rapid development of the social economy, China's substation is advancing towards modernization. Automation equipment and relay protection devices are widely used due to their excellent performance. This article introduces the AM series micro-computer protection devices, which provide corresponding protection functions for different protected objects in the Guiyang Vanke Emerald Riverside power distribution project. The logic of the backup power supply protection device is optimized based on actual conditions, making the power supply conditions more rigorous. This greatly improves the reliability, safety, and power supply quality of substation operations, benefiting the realization of comprehensive automation in substation and the implementation of unmanned or less manned operations.
