Hotel buildings usually have a large number of ventilation equipment and elevator equipment, and large central air conditioning unit, these equipment consist of typical nonlinear load:
Computer system equipment
……
The harmonic waves generated by these nonlinear loads flow into the distribution system, not only affect the reactive power compensation equipment, but also interfering with the normal operation of other electrical equipment, resulting in inefficient operation of the power system, increase of the failure rate, and increase of the overall cost.
Tuned reactive power compensation + concentrated active power filter system
Tuned type reactive power compensation + APF Choose tuned reactive power compensation to improve the system power factor. Choose APF active filter, connected to the main busbar for overall harmonic controlCompletely eliminate the neutral line current caused by third order harmonic, improve the quality of power. The solution can significantly improve the power factor of the system, 3rd and higher order harmonic mostly filtered. Effectively reduce the power loss caused by harmonic, greatly improve the utilization rate of designed system capacity |
