Solution description

There are various types of loads in the industrial sector, mainly including various motors (such as spinning motors, fans, water pumps, air compressors, etc.), variable frequency transmission devices, high-power rectifier equipment, medium-frequency furnaces, welding machines, UPS uninterruptible power supplies, and automated production line control systems. With the continuous improvement of industrial automation, nonlinear loads such as frequency converters and rectifiers are widely used, generating large harmonic currents during operation and causing instability in the power grid and distribution systems. At the same time, the power factor of motor inductive loads is generally low, generally only around 0.8, leading to reduced efficiency of distribution transformers, extra line heating, and increased line losses. The dual problems of harmonic pollution and insufficient reactive power not only affect the operational quality and reliability of various electrical equipment within enterprises but may also increase iron losses and stray losses in distribution transformers, and in severe cases, even cause system resonance hazards, threatening production safety. 

Recommended plan

In low-voltage distribution systems of industrial enterprises, IVL-RCS static filter compensation components are installed. This assembly consists of filter capacitors and filter reactors, specifically designed for reactive power compensation and filtering in power distribution systems affected by harmonics. The RCS series filter compensation module, with a reactance of 7%, has a tuning frequency of 189Hz, providing reliable reactive power compensation while effectively suppressing harmonic pollution at five or more times, mainly used in industrial settings. For industrial scenarios with high harmonic content, an IVL-APF active filter can be further configured to work in conjunction with the IVL-RCS static filter compensation component to achieve dual treatment effects of reactive power compensation and harmonic removal. By combining our company's production of high-voltage switchgear, low-voltage switchgear, box-type substations, cable branch boxes, switches, ring control cabinets, gas fillers, environmental protection cabinets, prefabricated cabins, and other complete sets of power equipment, we provide industrial enterprises with full-chain power quality solutions from high-voltage incoming lines to low-voltage distribution, ensuring the safe, stable, and efficient operation of distribution systems.
