Research on remote phase verification system for power systems based on 5G and Beidou technologies
摘要
Abstract
To solve the problem that a single-power-source substation cannot accurately perform potential transformer(PT)phase verification with an existing transmission line during commissioning,this paper proposes a remote phase verification system based on 5G and Beidou technologies.The proposed system comprises three parts:a Beidou satellite positioning system,a 5G-based positioning system,and a local clock synchronization system.Utilizing the high-precision positioning capabilities of 5G and Beidou,the overall system architecture is designed,along with a signal acquisition circuit and a phase synchronization and verification module.The phase verification module integrates both Beidou and 5G-based positioning to achieve accurate phase alignment,while a local clock synchronization module is introduced to enhance robustness against environmental interference.Simulation results demonstrate that the proposed system effec-tively solves the phase verification challenge in single-source substations.Moreover,it overcomes the traditional constraint that phase verification could only be performed when a dual-circuit power supply is available during the ener-gization process of newly built substations.关键词
