HKA series SVG
Features
HK-ASVG / 0.4kV series intelligent integrated filter compensation device, which can effectively control multiple harmonics while compensating the reactive power of the system, is connected in parallel to the low voltage side of the distribution transformer, and can detect the system through an external current transformer in real time. Phase current, and send the system current information to the internal controller for processing and analysis, calculate the reactive power component and harmonic content required by the system, and then invert the output and reactive power required by the power system through the three-level topology The components and harmonic currents are in opposite directions, and currents of the same size are injected into the power system to achieve dynamic compensation of reactive power and dynamic suppression of harmonics.
The device itself has anti-interference function, using dual DSP + FPGA control platform, triple protection logic, the system is reliable and stable.
