1.Introduction of YT Hybrid Static Var Generator System Static Var Generator + Capacitors Hybrid intelligent Reactive Power Compensation device adopts the configuration scheme combining static var generator and switching capacitor/reactor. According to the actual needs of users ,it can implement different reactive power compensation schemes to achieve the best combination of price and effec...
Power Factor Correctioni(PFC) Power factor correction (PFC) aims to improve power factor, and therefore power quality. It reduces the load on the electrical distribution system, increases energy efficiency and reduces electricity costs. It also decreases the likelihood of instability and failure of equipment. Power factor correction is obtained via the connection of capacitors(or Static Var...
Characteristics of reactive energy Reactive energy is not consumed, it is not useful for the system. Although it does not produce useful work, it is necessary to neutralize or compensate it. The reactive energy is measured in kVArh (Kilo volt-amp reactive hour). Reactive energy is created in devices or machinery that works with motors or transformers powered by the alternating current that reaches...

Power Quality Problems With the in-depth application of power electronic technology, the automation of the petrochemical industry has been continuously improved, and the nature of the load has also undergone qualitative changes. The increase of nonlinear and impact loads has brought about voltage flicker, three-phase imbalance, and excessive reactive power consumption. , harmonics and a series of ...
Background Jiangyin Huaxin Steel Cable Co., Ltd. produces thick zinc-coated prestressed steel wire, stranded wire and other steel wire, bar steel, steel wire metal products and stainless steel sheet materials. Power Quality Problem In the production process, the harmonic content of the power grid is relatively large, the power quality is poor, and the original reactive power compensation eq...
Background The input terminals of switching power supply and ups of Chinatelecom cloud computing Guizhou Information Park data center generate harmonic current, and the final harmonic current is collected on the general busbar. A large amount of harmonic current will cause the following harm to the communication room. Harmonic current will interfere with the communication signals of adjacent condu...
Power Quality Problems in Data Center Due to the uninterrupted power supply of the load in the data center room, a large number of UPS, switching power supplies and inverter air conditioners are used. The input stages of these devices are all three-phase arrangements, which generate a lot of harmonics when used. The switching power supply and UPS equipment first rectify the AC into DC, and then co...
