Function and purpose
The modular power quality power unit adopts the latest power electronic converter technology, combined with efficient software control algorithms, to achieve diversified power quality optimization functions. Power units with different functions can independently implement reactive power compensation, harmonic filtering, and three-phase unbalance management according to needs. They can also achieve multi-functional combinations to meet the needs of different capacities and different environments, and provide multiple solutions to solve power quality problems.
Detailed description
Parameters:
Rated capacity of single machine: APF(A):50/75/100/150
SVG(kvar): 50/100
Machine efficiency: ≥95%
Dynamic response time: ≤100us
