The reactive power consumed by the transformer is generally about 10% to 15% of its rated capacity, and its no-load reactive power is about 1/3 of the full load. Therefore, in order to improve power factor (PF) of the power system, the transformer should not operate at no-load or in a long-term low-load operation state. Vigorously improving the power factor of transformers, reducing line losses, a...
Project Name Daqing Electric Power Group Distribution Network Energy Conservation Comprehensive Management Project Project Background and Construction Objectives The distribution network of Daqing Power Group consists of 7 distribution stations, including Ranghulu, Longnan, Saltu, Dongfeng, Donghu, Honggang, and Chuangye. There are over 1000 transformers, with transformer capacities ...
Low voltage automatic contactor switched capacitor banks or filter banks typically use a delay time of 30 – 40 seconds between steps. This delay time is chosen to ensure that the capacitors have discharged prior to being re-connected. The long delay time limits the autobank’s ability to track rapidly changing loads. The slow response time may result in an overload condition in filter b...
Hybrid power factor correction Hybrid Active power factor correction systems utilise power electronics and digital control to achieve active reactive current compensation for specific and high performance solutions. YTPQC hybrid power factor correction system is comprised from both capacitor based and Static Var Generator(SVG,Active Power Factor correction). Static Var Generator is use...
YTPQC-AHF Active Harmonic Filter can realize 2nd to 50th harmonic compensation with full compensation or seletive compensaton, output compensation current follows the system harmonic variation, devoted to green power quality. Our AHF's compensation capacity(ratio) can be set freely by the customers, to realize harmonics compensation, reactive power compensation or imbalance compensation. YT...
