Design of a Customized Intelligent Electronic Device for Power Circuit Safety

Abstract

The Intelligent Electronic Devices (IEDs) are widely used to control the power circuits through an automated control device. The main motive of IEDs is to monitor the power flow, enable the control process and meter the changes. In some cases, the IEDs are employed as an electronic circuit breaker for providing a reliable operation. It is achieved by operating the relays through digital signals. The traditional methods have been using a mechanical system for operating the circuit breakers, which requires a manual operation for resting the breakers. The modern IEDs are developed to reset the operation by its own but such systems are heavily affected through data intrusions. Therefore, a programmed IED is developed in the proposed work to analyze if the decisions made by the IEDs are original or fake in a simulated observation. It is done with a mathematical averaging algorithm with respect to time for estimating a threshold. The experimental outcome indicates that the performance of the customized IED is better over the traditional IEDs. Moreover, the proposed device saves the energy distribution in a power system by avoiding the fake operations created in the IEDs through external intrusions.
