Analysis of Wind Farm Synchronization Impacted by Short Circuit of Grid Fault

A Comprehensive Mathematical Model for Analysis of WR-Resolvers under Stator Short Circuit Fault

Wound-Rotor (WR) resolvers are the most widely used position sensors in applications with harsh environmental conditions. However, their performance is exposed to failure due to the high risk of short circuit (SC) fault. Although the output current of the resolver is negligible, its thin copper wires increase the probability of the short circuit fault. To avoid the propagation of the turn-to-tu...

Dynamic modelling of wind farm grid interaction

This paper describes a dynamic model of a wind farm and its nearest utility grid. It is intended to use this model in studies addressing the dynamic interaction between a wind farm and a power system, both during normal operation of the wind farm and during transient grid fault events. The model comprises the substation w here the wind farm is connected, the internal power collection system of ...

Synchronization of Wind Farm Power System to Utility Grid under Voltage and Frequency Variations

The high penetration of micro-grid (MG) based on renewable distributed generators (DG) in the electrical network has brought about new issues on the stability and the transient operation of the grid. However, the disconnection and the reconnection of these local networks may give rise to undesired transient overcurrents and other damage that have to be avoided. In order to solve this problem, t...

Decreasing Distribution Generation Effects on Grid Short Circuit Level Using Superconducting Fault Current Limiter Through Updating Relays Set-Points

Power system protection at transmission and distribution levels based on overcurrent relays is essential based on their properties such as detection, stability, high speed, backup and error correction accuracy. Since distributed generation sources are connected to the power grid, they not only increase the short circuit level of the grid, but also disrupt the set point of main and backup relays...
