Abstract Traditional on‐load voltage regulating transformer are composed of segmented windings controlled by tap changers and power frequency transformers. The changer can only perform ‘step‐wise regulation’ is slow in response. A topology flexible presented this paper, which requires connecting a electronic converter at the transformer. PEC fully combine existing to achieve continuous stepless regulation function. This paper conducts modelling switch cycle average analyses range for...
Thermocline has a significant impact on marine fishery, navy submarine activity, ocean circulation and internal wave. In consideration of long range, low cost, high maneuverability, the AUV (Autonomous Underwater Vehicle) is an ideal platform for local precisely thermocline tracking. Combining with advantage yo-yo movement, this paper presents simple effective tracking method. According to definition thermocline, we set threshold, in real detect area, threshold can change adaptively, thus...
The large number of distributed generations connected to the power grid brings problems reverse flow and voltage rise. Due existence "negative regulating effect", traditional on-load tap changer (OLTC) needs reactive compensation device make good regulation. In this paper, flexible OLTC with back-to-back source converter (BTB-VSC) technology can generate a certain without device, which achieve better regulation effect. Meanwhile, based on principle sensitivity partition, we propose...
Voltage stability has always been a hot topic in power system research. Traditional On-Load Tap-Charger (OLTC) transformer is considered to play very important role the voltage stability. However, heavy load of distribution network, tap adjustment OLTC will lead shift critical stable operating point, which bring “negative regulating effect” adjustment, and even cause instability voltage. This paper presents Flexible Regulation (OLVR) based on electronic technology. The combination Power...
The application of on-load tap-charger (OLTC) transformer technology has become the most direct and effective way to solve voltage fluctuation power grid. With development active distribution technology, research focus regulation gradually turned direction arc free, fast intelligent. This paper presents a flexible topology based on electronic technology. (flexible OLVR) is combination traditional transformer, which can realize arcless switching, step-less regulation, other functions. In this...
Abstract The flexible on-load transformer can be adapted to different application scenarios by adding power electronic converter structures through the use of existing transformers. In this paper, a regulator structure based on floating capacitor multi-level AC/AC is proposed, which compensate input voltage primary side in same direction or opposite direction, combine with tap-changer, and also achieve fast stepless regulation. Finally, effectiveness proposed new topology verified simulation...
Abstract Traditional on-load tap charger (OLTC) transformer use mechanical switch or anti-parallel thyristor as changers. By changing the position of chargers, transformation ratio is changed, so to achieve discrete step voltage regulation function. In this paper a novel Flexible On-Load Voltage Regulator (Flexible OLVR) proposed, which integrated design Power Electronic Converter (PEC) and OLTC transformer. The converter set at primary side transformer, it could control output accurately...
