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...
The History Of Reactive Power Compensation If you are in the power industry, you must have heard of reactive power compensation. But you may not know much about it. What is reactive power compensation? We know that the power output of the power grid includes two parts: first, active power: directly consume electric energy, convert electric energy into mechanical energy, thermal energy,...
YT Electric single-phase active harmonic filter(AHF) is improved and upgraded on the basis of three-phase equipment. The A/B/C (L1/L2/L3) three-phase output is the same to achieve the purpose of single-phase compensation. Features of Single-phase AHF The device has a variety of compensation modes: reactive power compensation, harmonics current mitigation, which can be compensat...
Gelinmei (Wuxi) Energy Materials Co., Ltd. is a company that develops and produces lithium cobaltate and ternary materials. In the process of material production, some equipment (such as atmosphere furnace, air compressor, water chiller, etc.) will generate a large number of harmonics when working, which will do great harm to the whole power grid system. According to on-site data analysis and user...
Power Quality Problems Residential community power grids are low-voltage power distribution networks, generally connected to large power grids by 10/0.4kV transformers. Most of the loads in the grid work at three-phase 480V and single-phase 220V voltage levels, mainly small-capacity loads, such as air conditioners, refrigerators, and televisions. Machines and other household appliances. Most house...
Power Quality Problem The target enterprise produces shampoo, hair conditioner, moisturizing products, skin care products, liquid detergent, sanitary napkin, plastic molding products, cosmetics, washing powder, soap, etc. because the factory has more frequency conversion equipment, the harmonic current is large, and the voltage distortion rate is high, which endangers production safety and needs t...
Power Quality Problem Public utilities is indispensable to urban production and operation, residents' daily life, is the basis of urban survival and development and basic conditions, with the development and perfection of public utilities, improve the efficiency of urban labor, create a beautiful environment and good conditions for residents at the same time, also greatly increased the powe...
YTPQC-AHF Active Harmonic Filter YTPQC-AHF Active Harmonic Filter is a perfect and comprehensive solution to the power quality issues of power grid, such as harmonics, reactive power and 3 phase load unbalance. YTPQC-AHF which is in parallel to power grid can detect the harmonic wave in power grid in time, generate the reverse-phase compensation current through the converter and dynamica...
