Community and Building Solutions
1. Characteristics of Residential Area and Building Loads
Main equipment in residential areas and buildings are Variable frequency air conditioners, washing machines and other high-energy-consuming appliances (inductive loads). The extensive use of these devices will lead to large reactive power and low power factor in the circuit, and these devices use single-phase power supply. Uneven load distribution will cause three-phase imbalance.
2. Use of SVG devices Solution
2.1 Compensation Design Basis
Our company's SVG devices Can both govern three-phase imbalance and compensate for reactive power. The device uses a DSP controller to monitor the load current in real time. The controller drives the IGBT in real time to generate the required reactive power compensation current, ultimately achieving dynamic reactive power compensation and solving the three-phase imbalance.
Refer to the parameters provided by the user, such as the three-phase imbalance rate and transformer parameters on site, to calculate the required compensation capacity, and then select the corresponding SVG devices。
2.2 Effect after device use
The on-site equipment operates in a three-phase balanced state, and the neutral current of the power distribution network is significantly reduced; the on-site power factor is increased to above 0.9, reducing transmission losses, improving power grid operation efficiency, and saving electricity costs.
