The Overviews of Application of Three-Dimensional LiDar Technology in Operation and Maintenance of Overhead Transmission Lines in China

The paper briefly reviews the operational principles and commercialized conditions of airborne three-dimensional (3D) LiDar and terrestrial 3D LiDar. And then the representative functions of 3D LiDar that are developed for the operation and maintenance of overhead transmission lines (OTL) are described in detail. Besides, the problems associated with the process of applying 3D LiDar to OTL are analyzed. It is pointed out that it is necessary to make improvement to several aspects, including new functions development, standardization of application approaches and the simplification of data processing.

Specific Implementation

This paper briefly introduces the background, significance, and development status of 3D radar technology at home and abroad, and then explains the concept, working principle, system composition, and workflow of the radar system. Combined with the current development trend of smart grids, it focuses on the application scope of this technology in the field of transmission line construction, operation, and maintenance. Then, through the specific implementation of the project cases, the daily operation and maintenance of four 500 kV transmission lines in Nanjing have played a certain guiding role. Finally, according to the development trend of smart grid and the actual demand of power system production and business integration, this paper briefly prospects the function expansion of this technology in transmission line operation evaluation, fault analysis and diagnosis, emergency rescue plan formulation, and other fields.

Preliminary Application

Based on a brief introduction of the operational principle of terrestrial 3D LiDar, this paper describes some typical defects detection methods of security distance in the overhead transmission line with living examples. These tests are realized by the Z+F Imager 5010 terrestrial 3D LiDar and Polyworks. The research results show that terrestrial LiDar technology can achieve the defect evaluation of defect detection of security distance in the overhead transmission lines. And this technology has many advantages, such as portable, security, intuitive and high precision.
