Abstract
Smart sensing and power line tracking is very important in a smart grid system. Illegal electricity usage can be detected by remote current measurement on overhead power lines using an inspection robot. There is a need for accurate detection methods of illegal electricity usage. Stable and correct power line tracking is a very prominent issue. In order to correctly track and make accurate measurements, the swing path of a power line should be previously fitted and predicted by a mathematical function using an inspection robot. After this, the remote inspection robot can follow the power line and measure the current. This paper presents a new power line tracking method using parabolic and circle fitting algorithms for illegal electricity detection. We demonstrate the effectiveness of the proposed tracking method by simulation and experimental results.
Highlights
One of the aspects that characterizes the development of a society is its energy consumption in all of its forms, where the amount of consumption is steadily increasing
The same problem exists in Iran [5], and even Mongolia is seeking an optimal solution for remote detection of illegal electricity usage [6]
There, illegal electricity usage can be detected by measuring the line impedance when the power distribution system of all users are disconnected and a low-voltage signal having a high frequency component is transmitted to the power distribution system [5]
Summary
One of the aspects that characterizes the development of a society is its energy consumption in all of its forms, where the amount of consumption is steadily increasing. Remote detection methods in real time are classified as follows: Smart meter method, high frequency signal processing method, and inspection robot based methods [8]. There, illegal electricity usage can be detected by measuring the line impedance when the power distribution system of all users are disconnected and a low-voltage signal having a high frequency component is transmitted to the power distribution system [5]. If an illegal electricity usage occurs on the power delivery system, the measured value of MEM and the summation of each TSM measurements will not be equivalent This paper presents a new power line tracking algorithm for mobile sensing and detection of illegal electricity usage based on an inspection robot
