Abstract

Financially effective maintenance and monitoring of the power system is one of the most important functions of today's power industry to ensure high quality and reliability of power supply to consumers. This is extremely important because due to unexpected failures, utilities and consumers will also face many losses. Ideal power networks can be contacted through reducing the cost of maintenance and maximizing the service life and reliability of the existing lifetime. But both goals can not be achieved simultaneously, timely preventive maintenance can dramatically reduce system failures. At present, there are three maintenance methods employed by utilities: corrective maintenance, scheduled maintenance and position-based maintenance. The following block diagram shows the important characteristics of different maintenance methods.

Corrective maintenance is dominant in today's power industry, this method is inactive, i.e. no failure will be taken unless there is no failure. On the other hand, scheduled maintenance shows periodic maintenance done at pre-defined time intervals. Position-based maintenance is defined as schematic maintenance based on the continuous monitoring of the position of the device. Position-based maintenance is very attractive because maintenance is only done when components of electricity system are required. The only fault cost of condition-based maintenance is monitoring the cost. To implement condition-based maintenance, expensive surveillance equipment and additional technicians are required. Mobile monitoring solves this problem

Mobile monitoring involves the development of a robot platform that carries the sensor array. It constantly patrols the power cable network, detects initial failures and estimates the aging status of electrical insulation. For the presence of reliability, aging and early mistakes, monitoring of electrical energy systems in real-time, large quantity of data distributed from distributed sensor networks and centralized processing is required. In order to solve this task, multi-purpose efforts are required to combine areas such as sensing, signal processing, control, communication and robotics.

With any preventive maintenance technique, the efforts spent in monitoring the situation are considered appropriate due to the reduction in defect and damage resulting from damages and damage to the equipment as a result of the loss of electricity. In addition, it is a well recognized fact in the surveillance and surveillance areas that the measurement of distributed system parameters has high accuracy when it is completed using sensing techniques. In addition to improving sensitivity and enhancing the subsequent reliability, there are many other advantages in the use of robot platforms for the maintenance of electrical systems, such as hazardous and highly specialized operations such as live line maintenance, rather than human workers.
