Detailed introduction
Product Features
HK-ASVG/0.4kV train intelligent comprehensive filtering and compensation device can effectively control multiple harmonics while compensating the reactive power of the system. It is connected to the low-voltage side of the distribution transformer in parallel. It can detect the three-phase current of the system in real time through an external current transformer, and send the system current information to the internal controller for processing and analysis, and calculate the reactive component and harmonic content required by the system, then, through the three-level topology structure, the direction of the reactive component and harmonic current required by the power system is opposite, and the current of the same size is 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.
