Power Quality Problems In Commercial Complexes
A large number of automation equipment in commercial complex automation systems require high-quality power supplies. However, a considerable part of these devices have become disturbance sources that cause harmonic distortion in low-voltage power supply systems due to their nonlinear load characteristics. It will cause pollution of the power distribution system and cause harm to the surrounding communication system and even the equipment outside the power distribution system.
There are two main sources of harmonics in commercial complexes:
Hazards and Influence
YT Solutions
The loads in the commercial complex system mainly include lighting, elevators, central air conditioners, etc. Among them, single-phase load equipment such as lighting mainly generates 3 harmonics, while elevators, central air conditioners, etc. use inverter-driven loads mainly generate 5th, 7th , 11th, 13th ordder harmonics. According to the current situation of harmonics in commercial complex systems, the best solution is to use Active Harmonic Filtering technology. The YT Active Harmonic Filter device adopts advanced power electronic technology to detect the harmonics in the power grid in real time, and generates an inverse compensation current through the converter to dynamically filter out the harmonics in the power grid.
