STATCOM and UPQC: options to enhance fault-ride-through capability of a fixed speed wind generator

6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012), 2012
The enhancement of fault-ride through (FRT) capability of a Fixed Speed Induction Generator (FSIG) with the help of a Unified Power Quality Conditioner (UPQC) and STATCOM are examined in this paper. The FRT performance of these equipments are evaluated and compared in accordance with Irish Grid Code requirement. A simulation study carried out on a 2 MW

Intelligent Islanding and Seamless Reconnection Technique for Microgrid With UPQC

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2015
A new proposal for the placement, integration, and control of unified power quality conditioner (UPQC) in distributed generation (DG)-based grid connected/autonomous microgrid/microgeneration (μ G) system has been presented here. The DG converters (with storage) and the shunt part of the UPQC Active Power Filter (APFsh) is placed at the Point of Common

UPQC: An Exhaustive Solution to Improve Power Quality

2020 4th International Conference on Electronics, Communication and Aerospace Technology (ICECA), 2020
To improve power quality in the distribution system, various custom power devices like dynamic voltage restorer (DVR), distribution static synchronous compensator (D-STATCOM), and unified power quality conditioner (UPQC) are used. DVR takes care of voltage related problems viz. voltage sag, swell, interruption. D-STATCOM either generates or absorbs the

Complex wavelet based control strategy for UPQC

2010 Joint International Conference on Power Electronics, Drives and Energy Systems & 2010 Power India, 2010
This paper discusses the utilization of complex continuous wavelet transform based on B-spline function for reference voltages and currents extraction which are used for compensating power quality disturbances by using unified power quality conditioner. The major advantages of choosing B-spline function are the reduction of computation time and ease of

Performance analysis of UPQC for total harmonic distortion

World Journal of Advanced Engineering Technology and Sciences
In order to mitigate power quality (PQ) issues in electrical power systems, the Unified Power Quality Conditioner (UPQC) is the main topic of this research study. Power Quality problems, such as voltage sag, voltage swell, harmonics, and flicker, are brought on by the increase in nonlinear loads and the integration of renewable energy sources into ...
