Remote control of intelligent circuit breakers in power systems based on wireless communication technology

Given that traditional circuit breakers often use wired connections, which result in complex wiring and difficult maintenance, this paper proposes a remote control scheme for intelligent circuit breakers in power systems based on wireless communication technology. Deploy Hall sensors at the operation site of the power system to collect real-time voltage data of the closing and opening capacitors of intelligent circuit breakers, and then wirelessly transmit it to the remote monitoring center through 5G communication technology. At the remote monitoring center, based on the error between the received voltage data and the target set value, combined with PID algorithm, the corresponding control signal is calculated to drive the operating mechanism to remotely control the opening and closing of the intelligent circuit breaker in the power system. The experimental results show that the research method performs well in the remote control accuracy, response speed, and voltage stability of intelligent circuit breakers in power systems, effectively improving the intelligence and remote control capabilities of circuit breakers.
