Core Viewpoint - The State Grid Jinchang Power Supply Company has successfully completed the maintenance and upgrade of clock synchronization devices at 19 substations, enhancing the reliability and precision of the power supply system through the implementation of a dual BeiDou satellite timing system [1][2]. Group 1: Technology and Equipment - The upgraded SHTS-2000 clock synchronization device is a domestically developed, secure, and independent dual BeiDou timing system, providing precise timing signals for various power station equipment [1]. - The new BeiDou timing service offers a precision better than 20 nanoseconds, ensuring strict time synchronization requirements for relay protection and automation devices [2]. - The dual BeiDou configuration creates a redundant architecture that mitigates risks from signal obstruction, equipment failure, or electromagnetic interference [2]. Group 2: Implementation and Impact - The maintenance and upgrade work has been completed for 4 330 kV, 11 110 kV, and 4 35 kV substations, fully applying the dual BeiDou timing system in the Jinchang region's power grid [2]. - The company aims to leverage the technological advantages of the BeiDou timing system to explore new boundaries in power time synchronization technology and promote further upgrades and optimizations of substation equipment [2]. - This initiative contributes to building a more intelligent, stable, and secure power network, supporting the high-quality development of the regional economy and society [2].
