Plan Description

Load Types: In commercial residential areas, this includes household appliances such as TVs, refrigerators, air conditioners, sterilizers, dishwashers, and microwaves, as well as personal computers and various electronic devices used in offices and homes. As residents’ living standards continue to improve, electricity consumption in homes and commercial spaces has increased significantly. Especially during peak summer usage, inductive loads like air conditioners operate simultaneously, causing a sharp rise in reactive current and putting considerable stress on the low-voltage distribution network. At the same time, a large number of nonlinear electronic devices generate harmonic currents, making harmonic distortion in the distribution network increasingly prominent. The neutral line carries a high level of triple-order harmonics, odd harmonics are significant in phase currents, and harmonic losses cannot be ignored. If these issues are not effectively managed, they may lead to overheating of distribution lines, reduced equipment lifespan, and capacitor damage, among other risks.

Recommended Solution

For the low-voltage distribution system in commercial residential projects, install IVL-RCS static filter compensation units. These units not only provide dynamic reactive power compensation and improve power factor, but also effectively suppress harmonic amplification through series reactors, absorbing most of the harmonic current. Paired with our company’s high-voltage switchgear, low-voltage switchgear, box-type substations, cable branch boxes, switching stations, ring main units, gas-insulated switchgear, eco-friendly cabinets, and prefabricated cabins, we can offer a complete power distribution solution from high-voltage input to low-voltage output for commercial residential projects. Equipment selection strictly follows residential distribution facility standards to ensure that the system operates safely, reliably, and economically.

Plan Benefits

This solution effectively improves the power factor of low-voltage networks in residential areas, reducing the flow of reactive current in distribution lines and lowering line losses; it increases the effective output of transformers, delaying the need for investment in grid capacity expansion; it suppresses harmonic amplification, protecting the distribution system and electrical equipment to ensure safe operation and reliable power quality. Furthermore, it helps avoid penalties from power companies due to low power factor. The solution offers both energy savings and operational reliability, providing high-quality power assurance for commercial residential projects.
