Design of Wireless Monitoring and Controlling System of Power Transmission Lines

Abstract

– In the traditional overhead power transmission lines systems, the detection of the faults in the electric lines is difficult and may lead to comparatively longer time to repair them. Specifically, the faults resulting from loads or current leakage are difficult to detect. This paper presents a monitoring system to detect such faults. The weather conditions such as humidity, temperature, and rainfall, as well as the current flow of the line are monitored to detect the faults and highlighted the specified fault region. The system disconnects the power when an over value exists. The design consists of a group of nodes, each one contains a transmitter and receiver unit. The transmitter consists of a group of sensors namely DHT11 sensor, rain sensor and ACS755 which sends the measured information as frames via Xbee technology. All these nodes send their data to the main node. Virtual Serial Port Emulator VSPE used to access multiple nodes on the main pc. The result in this paper shows the performance of the system when all the parameters were within the allowed range. The design also was simulated in different out of range values for over current, high humidity and high rainfall. The obtained results were accurate and prove that it works successfully.
