Network fault monitoring in Grid

2011 Third International Conference on Advanced Computing, 2011
Grid resources having heterogeneous architecture being geographically distributed and interconnected via unreliable network media are at the risk of failure which proves the need for an efficient fault monitoring framework. The traditional network fault monitoring systems based on the centralized client/server architecture have limited efficiency and ...

Fault Isolation in DC Grids

2020
DC fault current breaking devices are important components for enabling robust protection of the dc system. This chapter will present the ongoing developments regarding the dc fault isolation devices. There are two major trends in dc fault isolation, namely based on, dc circuit breaker (DCCB) and converter-based solution.

RT-GRID: a real-time, fault-tolerant grid model

Proceedings of the Fourth International Conference on Parallel and Distributed Computing, Applications and Technologies, 2003
Computational grids bring together various distributed resources belonging to different organizations, and provide a high-performance computing environment. However, there is another application category, with the requirement of time constraints and fault tolerance, which needs to be processed in such a high-performance platform.

Control of Grid Connected Converters Under Unbalanced Grid Faults

2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018
A grid connected inverter with an unbalanced voltage at the point of common coupling creates oscillation in DC link voltage at twice the grid frequency and inject highly distorted current into the grid. In this paper analytical expression for oscillation of DC link voltage and distortion in current injected to the grid are derived.

Grid Faults and Component Failures

2011
The Chapter describes grid faults; mainly short circuits and trips of big generators. These common faults or credible events affect system stability and security. The Chapter also discusses component failures, their causes and the calculation of failure rate estimates and unavailabilities. Fault and failure statistics are briefly described, too.

Fault-ride-through schemes of grid-interfaced DFIG: A comparative study under symmetrical grid faults

2017 International Symposium on Recent Advances in Electrical Engineering (RAEE), 2017
The stabilized operation of Doubly Fed Induction Generator (DFIG) during symmetrical faults is a demanding problem for power system engineers. Transient peaks, oscillations, and higher-order frequency harmonics in DC link voltage and rotor circuitry will lead to the violations of the grid-code objectives during grid faults.

Stability study of a grid fault

2015 16th International Conference on Sciences and Techniques of Automatic Control and Computer Engineering (STA), 2015
The exploitation of grids has witnessed a rapid increase during the last years. Indeed, a grid fault has repercussions on the quality of energy produced and transmitted to the users and thus on its stability. Consequently, regulators are installed to restore the stability and improve the performance of the power system.
