Compensation function
It can realize any combination of harmonic control, reactive power compensation, and three-phase unbalanced current adjustment, and can set the priority of each function according to the load environment and demand to realize the compensation of typical power quality problems.
Wide filtering range and fast response
2 ~ 50 harmonics can be compensated at the same time, or a specific harmonic can be selected for compensation, and the total current distortion rate after compensation is less than 5%.
Using full digital control, the harmonic current detection algorithm is based on the TTA algorithm of time domain transformation, which quickly separates the instantaneous value of each harmonic current, greatly improves the compensation response time, and truly achieves a full response of 10ms.
Core components
IGBT module imported from Germany, three-level topology.
American TIDSP control chip and A LTERA's CYCLONE III series FPGA chip constitute a powerful three-core control system.
American TI's double-ended high-speed input 12-bit A/D data conversion chip makes signal sampling more reliable.
Layered heat dissipation structure design
The structure design of layered heat dissipation makes the air duct independent, the heat dissipation performance is better, and the interference of dust and other pollutants on the control system is effectively isolated.
Fan independent disassembly design
The fan can be disassembled independently, and the replacement is easy and convenient, which enhances the reliability of heat dissipation.
Modular Design
A variety of capacity modules can be installed in any combination to improve the reliability and maintainability of the whole machine.
Humanized interface design
Using a high-resolution 5-inch LCD touch screen, it can monitor various operating data of the product in real time, and change the control parameters online. The operation is simple, and it can be remotely controlled through the mobile APP. The display interface design is novel and beautiful.
