Shipboard microgrids (SBMGs) are becoming increasingly popular in the power industry due to their potential for reducing fossil-fuel usage and increasing production. However, operating SBMGs poses significant challenges operational environmental constraints. To address these challenges, intelligent control, management, protection strategies necessary ensure safe operation under complex uncertain conditions. This paper provides a comprehensive review of SBMGs, including classifications,...
An intelligent electronic device (IED) is presented in this article to provide rapid fault detection and location method for ship power systems (SPSs). The IED employs the pilot distance protection scheme with IEC 61850 communication network. proposed depends on high-frequency transient feature which components of current voltage are extracted analyzed estimate system's impedance fault's by comparing estimated prescribed threshold. After that, IEDs can communicate each other based protect...
This paper introduces an innovative adaptive scheme for detecting and locating faults in DC-zonal shipboard microgrids (SBMGs). relies on the estimation of high-frequency impedance. The proposed is implemented intelligent electronic device (IED) which Fast Fourier Transform applied to obtain components current voltage at each node. Then, these are exchanged between two IEDs that protect same line by using IEC 61850 GOOSE-based communication system. estimated impedance calculated compared...
Multiterminal High-Voltage Direct Current (MT-HVDC) systems offer numerous benefits compared to conventional alternating current (AC) power systems, including higher density and improved efficiency. However, the need for adequate protection schemes HVDC remains a significant obstacle their widespread adoption. Much attention has been given developing methods address this. Moreover, of MT-HVDC presents challenge due bidirectional flow, dynamic system characteristics, fault characteristics...
Shipboard microgrids must have adequate protection schemes to be more reliable, provide the ability prevent spread of outages, and sustain continuous service customers. The intelligent distance relay that is presented in this paper provides such an scheme. performed by Intelligent Electronic Device (IED) based on IEC61850 communication network. This solves a problem exists conventional relays not protecting whole line instantaneously. proposed scheme has two stages. Firstly, fault detected...
The zonal DC Voltage shipboard microgrid has many issues in terms of the protection side. A novel adaptive pilot, distance scheme, is proposed this paper for to make system more reliable, selective, and rapidly detect fault. scheme based on three stages. Firstly, it detects whether there a fault by applying Fourier transform (FT) method analyze voltage current measurements. Secondly, location detected determining which line selecting proper zone each relay. Thirdly, communication signals are...
Multiterminal High-Voltage Direct Current (MTHVDC) systems have emerged as a promising solution to enhance power transmission efficiency and capacity.
