Real-time detection of harmonic current, through instantaneous current tracking control, which can automatically track the harmonic change of load with a high controllability and fast response.
The filtering performance is not affected by system impedance. Resonance prediction control can effectively prevent capacitance attenuation and avoid resonance risk. It can be adjusted dynamically in single phase to improve load imbalance, restrain system oscillation and improve system stability. Passive branch can use zero-crossing switching.
Single cabinet integrates active and passive modules, active modules are seamlessly parallel, with capacity free to choose, arbitrary expansion, easy maintenance.
With perfect protections , features like overvoltage, undervoltage protection, overcurrent protection, overheat protection and comprehensive control protection, to ensure the long-term stable operation of the device without equipment overload.
Integrated control and unit integration, the whole equipment adopts an intelligent control unit to control the real-time filtering of the active filter module and the automatic switching of the passive compensation module.
