Reactive Power Compensation and Power Quality Management Device
General
The APF features a modular design with compact size and lightweight construction, enabling installation without requiring cranes or forklifts, thereby saving time and labor. Its wall-mounted design offers flexible installation, making it particularly suitable for space-constrained locations.
The APF provides multiple monitoring options tailored to different models, including:
-
3.8-inch LCD display
-
4.3-inch color touchscreen
-
8-inch full-color LCD touchscreen
-
Background monitoring software
This versatility ensures adaptability to diverse user requirements.
General
The ASVG continuously monitors load current through external current transformers (CTs). Its internal DSP calculates and extracts the reactive and harmonic components from the load current. Subsequently, it generates PFM signals to control the IGBT inverter, producing precise reactive current and low-order harmonic currents as configured. This achieves combined reactive power compensation and harmonic mitigation.
General
The ASVG utilizes external current transformers (CT) to monitor load current in real-time. The internal DSP calculates and extracts the reactive power components and harmonics from the measured load current. It then sends PFM signals to control the IGBT-based inverter, which generates the required reactive current and low-order harmonic currents according to preset parameters. This achieves simultaneous reactive power compensation and harmonic suppression.
