Fault Detection and Isolation of DC Micro-Grid

Abstract

In a microgrid, faults can lead to voltage instability, which can produce voltage sags, swells, or even a full collapse of the voltage. This may result in electrical equipment damage and interfere with the microgrid's operation. Faults can also produce safety risks including fire, explosion, or electrocution, which can endanger employees and harm equipment. By isolating or shutting down the system when a malfunction is found, the danger of harm or injury is reduced. The purpose of fault isolation and detection in a DC microgrid is to guarantee the microgrid's dependability and safety. The microgrid's flaws are found using fault detection and isolation (FDI) techniques, which are then used to isolate them so they won't influence other system components. The microgrid's downtime can be reduced by immediately identifying and isolating issues, ensuring a steady supply of electricity to the associated loads. Additionally, fault isolation and detection can stop problems from spreading to other system components, which can reduce the severity of the fault's harm. The purpose of this research is to identify and isolate faults that occur in DC microgrids, as well as to minimise their impact. In this project fault detection and isolation is properly done, for detecting a fault microprocessor is used which continuously monitor the values of current and voltage and for isolation of microgrid relay is used. We are successfully providing the circuit which detects the fault and isolate within the time which reduces the severity of fault and protect the healthy
