An UPQC Based on Thyristor and Ultra Capacitor

Kongzhi Yu Xinxi Jishu, 2015
The traditional UPQC(unified power quality conditioner) cannot realize voltage compensation when the system’s power voltage deeply drops or interrupts in a short time. A new type of UPQC was proposed, which was added bidirectional thyristor, ultra energy

Power quality solutions for rail transport using AI-based unified power quality conditioners

Discover Applied Sciences
Abstract This research proposes an AI-controlled Unified Power Quality Conditioner (AI-UPQC) to enhance power quality in railway power supply systems. The AI-UPQC utilizes artificial neural networks (ANNs) to generate optimal reference signals for controlling the series and shunt active power filters (APFs).

Unified power quality conditioner: Design, simulation and experimental analysis

, 2020
Güç kalitesi problemi gerilim ve/veya akımın nominal sinüs dalga formundan sapması olarak tanımlanabilir. Güç kalitesi problemleri genellikle gerilim düşümleri/yükselmeleri ve harmonikli akımlar ile ilgilidir. Güç kalitesi problemlerine çüzüm getiren özel Güç Donanımları son yıllarda büyük bir önem kazanmıstır.
