China XPQ Static Var Generator 400V/690V Factory - Improve Power Quality with Reactive Power Compensation
Features
Compensation ability
The system can adjust the reactive power output based on site conditions to prevent overcompensation or undercompensation, ensuring a power factor of 0.99.
Fast response
Fully digital control. The harmonic current detection utilizes an efficient TTA algorithm based on time domain exchange. This enables quick and accurate calculation of the instantaneous value of reactive current, leading to a significant improvement in compensation response time and achieving a full response within 10ms.
High-end quality of core components
German original IGBT module, three-level topology. The control system is comprised of the American TIDSP control chip, as well as ALTERA and CYCLONE 3 series FPGA chips, making it a powerful three-core system. Additionally, TI's double-ended high-speed input 12-bit A/D data conversion chip enhances the accuracy and reliability of signal sampling.
Efficient heat dissipation
The layered heat dissipation design allows for independent air ducts, leading to improved heat dissipation performance and effectively preventing dust and other pollutants from affecting the control system.
Independent fan, detachable
The fans can be easily disassembled and reassembled independently, enhancing heat dissipation reliability.
Modular design
Various capacity modules can be installed in any combination to improve the reliability and maintainability of the whole machine.
Human-Machine Interface
Single module can be equipped with a 5-inch LCD touchscreen, and multiple modules can have an external 7-inch LCD touchscreen. It supports real-time monitoring of operating data and online change of control parameters. It is simple to operate and can be equipped with an optional mobile phone APP for remote control.
