Modern Technologies for Monitoring Overhead Transmission Lines

Abstract

Relevance: in recent years, due to the energy transition taking place in many countries of the world, energy transition processes are taking place in Uzbekistan. The transition is associated with a turn to green energy and serious problems of diversification of energy sources, development of market relations, digitalization and intellectualization of the energy sector. In such conditions, at all stages of the transition, it is necessary to ensure the reliability of electricity supply to consumers and the provision of electric power systems (EPS) in various modes. Therefore, conducting a study on the use of reliable methods for providing consumers with high-quality electrical power, including when operating wind and solar power plants with unstable modes, is relevant. One of such methods is operational demand response.

Aim: Efficient management of power networks, increasing energy transmission efficiency, and reducing maintenance costs by monitoring the temperature, mechanical tension, sag, icing, and electrical parameters of OHTL conductors.

Methods: Telemetric monitoring of electrical and mechanical parameters of conductors; Utilization of modern monitoring systems such as CAT-1 and OTLM; Application of sensors, strain gauges, accelerometers, and meteorological stations; Data transmission via wireless communication channels (GSM, GPRS, ZigBee, xBee) and processing in SCADA systems.

Results: Power transmission efficiency increases by up to 15–30%; Failure detection and fault localization become faster, reducing maintenance costs; Network reliability improves by identifying critical conductor states, icing, and resonance phenomena.
