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...
Why power factor is lower at power grid with solar? The active power and reactive power consumed by the system is fixed. When there is photovoltaic, photovoltaic provides active power, so the active power provided by the system decreases, and the reactive power remains unchanged, so the power factor decreases. If the active power provided by photovoltaics is close to the active power consumed by t...
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...
Passive Harmonic Filter The simplest of all filters are the ones built using just resistors, capacitors and inductors. Such filters are called passive harmoinc filters, as they are constructed from passive components. In electronics, passive components are those which do not produce energy of their own. They are only capable of dissipating energy (in the case of resistors) or storing energy (in th...
YTPQC-AHF Active Harmonic Filter is a comprehensive and flexible solution for power quality problems. It provides the advanced control and proven reliability that your facility needs to solve power quality issues. It monitors the load current and very quickly responds to the power system distortion as it develops. A corrective current is injected to effectively cancel out the harmonics required fr...
