Abstract

The power transmission line is one of most critical components in electrical power system. In order to enhance the reliability of the large power systems, an advanced and efficient Wireless Sensor Network (WSN) must be employed along power transmission line. However, time delay has emerged as one of the most critical issues in the design of WSN-based monitoring network of transmission lines. This paper proposes a new model for WSN for monitoring High Voltage Transmission Line (HVTL) which improves the needed time delay to transmit the measured quantity from transmission line towers to the control center. The proposed design considers the broadband power line communication (BPLC) technologies to transmit the collected data from group of towers to the nearest substation. To evaluate the performance of proposed model, the maximum time delay in data flow for the proposed model is determined in mathematical form and compared with other common models. The results of this paper demonstrate that the maximum time delay of proposed model less than the other common models, especially when advanced wireless communication, such as 4G and 5G, is used between the relay nodes. Based on the simulation results, the proposed WSN-based transmission line monitoring is efficient, powerful, reliable, and applicable to meet the smart grid requirements.

Highlights

The electrical power system consists of hundred or even thousands of substations which are connected with power plants, lines, transformers and consumers
The simulation results of various network model of Wireless Sensor Network (WSN) for power transmission line monitoring has been done to evaluate the performance of Linear Network Model (LNM), direct link network model (DLNM) and the proposed PBLNM model
Since the WSN Wireless Sensor Network (WSN) is a technology that allows sensors to coordinate among each other, the time delay is the critical parameter to evaluate the performance of WSN-based transmission line monitoring network

Summary

Introduction

The electrical power system consists of hundred or even thousands of substations which are connected with power plants, lines, transformers and consumers. The authors in [10] [11] were the first to propose wireless sensor technology in the power transmission line monitoring; they suggested the use of wireless sensors to estimate the line status and the conductor temperature based on intelligent technique. In their work, they assumed that the sensors are installed along the transmission line. They assumed that the substations have a direct communication link with the main control center through fiber optic cables It means that the relay nodes form a linear network between two substations located at the ends of transmission line.
