Abstract

In order to make the operation of the line more safe and reliable, the state monitoring is needed and the remote transmission of data is realized on this basis. This paper proposes a variety of communication modes suitable for transmission line condition monitoring data transmission. The corresponding communication system design is given for different application conditions. The development and application of data transmission technology for condition monitoring of transmission lines are discussed in combination with two different schemes of typical design and distributed intelligent fault diagnosis system.

Highlights

  • The construction of smart grid is to achieve the overall strategic planning goal of power development[1,2]

  • The initial maintenance methods are determined by referring to the previous traditional experience, and the implementation technology is poor and relatively rigid[35]

  • CMG is a kind of gateway equipment, which is divided into two different types: line and substation. It can remotely connect with the condition monitoring agent, obtain the condition monitoring data and verify it, so as to realize the reasonable control of data information

Summary

Introduction

The construction of smart grid is to achieve the overall strategic planning goal of power development[1,2]. It is necessary to build the line condition monitoring system, adopt more new technologies, use more reliable communication methods, realize the realtime data transmission, speed up the transmission speed, reduce the communication cost, improve the management and control level of transmission line, and deal with emergencies in time. With the continuous development of sensor equipment, communication network, computer technology and other disciplines, the current transmission line has high technical support in data storage, remote measurement, real-time response and other aspects. It makes the transmission line online monitoring technology level achieve better development, so that the data long-distance transmission technology can be realized
