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...
Industry Background Jiangyin Kangrun Co., Ltd. is a modern production factory specializing in spinning, fabric textile processing, textile raw materials sales and finished textile products production. With the development of social economy, many textile enterprises have updated their equipment in order to improve the product quality, and a large number of frequency conversion, DC and other equipme...
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...
In modern industrial processes, the number of nonlinear loads - known to be a major source of current harmonics - is constantly growing. At the same time, the number of reactive-power compensators operating in these networks is growing too. Though the compensators are not the source of harmonic distortions, they may cause high amplifications of harmonics by creating resonance conditions. This can ...
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...
Power Quality Problem By the end of 2020, China railway operating mileage reached 146,000 kilometers, and the high-speed railway operating mileage reached 37,900 kilometers, ranking first in the world. High-speed rail traction transformers generally use 12 or 24 pulse rectification, which will generate 11th and 13th harmonics; power distribution transformer loads mainly include inverters, UPS...
