Q: What functions does the XPQ Active Power Filter perform?
The XPQ system provides comprehensive power quality compensation by performing three main functions: harmonic control, reactive power compensation, and regulation of three-phase unbalanced currents. These functions can be combined and prioritized based on load environments.
Q: What is the harmonic filtering range and response speed of the system?
The system can compensate for 2 to 50 harmonics simultaneously or target specific harmonics. Driven by the efficient TTA algorithm, it delivers a full response time of just 10ms and guarantees a post-compensation total current distortion rate of less than 5%.
Q: What core components ensure the high quality of the XPQ system?
The XPQ system features top-tier hardware, including a German original IGBT module with a three-level topology, control systems powered by American TI DSP control chips alongside ALTERA and CYCLONE 3 series FPGA chips, and a TI 12-bit A/D data conversion chip for precise signal sampling.
Q: How does the cooling system protect the module from dust and overheating?
It utilizes a layered heat dissipation design that creates an independent air duct, isolating dust and other pollutants from sensitive electronics. The cooling system also features an independent, detachable fan that can be easily disassembled for quick maintenance.
Q: How can the XPQ system be monitored and controlled?
Single modules can be monitored using a 5-inch LCD touchscreen, while multiple modules can be linked to an external 7-inch LCD touchscreen. The system allows for real-time operating data monitoring, online parameter modification, and remote control via a mobile app.
Q: What is the difference between the 3-phase 4-wire and 3-phase 3-wire systems?
The 3-phase 4-wire configuration is specifically suitable for power grid systems with neutral lines, allowing the unit to filter out both phase line and neutral line harmonics simultaneously.
