Technical parameters
BLUEWAVE active filter
The BLUEWAVE three-level active power filter can be used to directly or indirectly measure the current, harmonic and reactive power components injected into the grid by nonlinear loads in the digital control unit through connected external current transformers. Active filter continuously generates compensation current, cancels harmonic components and load reactive current, and makes only fundamental current in the grid. Active power filter can adapt to the change of load and harmonic content.
Main functions of BLUEWAVE three-level active filter system:
- Harmonic filtering function
- Up to 50 harmonics can be filtered;
- Within the system capacity, the effective filtering ability of target harmonics reaches 97%.
- The system can provide two filtering modes:
(1) for less than 50 harmonic automatic filter all;
(2) single harmonic selective filtering mode;
- In the single-harmonic selective filtering mode, 24 harmonics can be randomly selected from all odd harmonics within the range of 50, and the filtering - ratio of each harmonic can be set.
- Fast harmonic compensation capability (response time ≤5ms);
