Delta’s PQC Series APF is connected in parallel with non-linear loads, and uses one set of current transformers (CT) to detect the load current. It calculates each order harmonic current by FFT algorithms in its DSP microchips, and then generates a compensating current with the same amplitude but opposite phase angles to the detected harmonic current, which cancels out the original load harmonics. The PQC series APF not only eliminates harmonic current from the load side, but it also mitigates harmonic voltage caused by harmonic currents. The APF system can also improve power factor (PF) and correct load imbalances in the power system.
The series has a modular design, which adopted 3-level inverter topology with 12 pcs discrete IGBT and DC capacitor components the Delta Active Power Filter system consists of one or several APF modules and a display. There are two types of displays, one is Touch Panel Human Machine Interface (HMI), which is touch-screen type, and the other one is non-touch-screen type, call Liquid Crystal Monitor (LCM). Each APF module is an independent harmonic filtering system, and users can change the harmonic filtering system rating by adding or removing APF modules. According to the mounting type, Delta PQC series APF can be divided into modular APF (rack mounting) and wall-mounted solutions.
The principle of the SVG is very similar to that of Active Power Filter. When the load is generating inductive or capacitive current, it makes load current lagging or leading the voltage. SVG detects the phase angle difference and generates leading or lagging current into the grid, making the phase angle of current almost the same as that of voltage on the transformer side, which means fundamental power factor is unit. Delta’s PQC series SVG is also capable of correcting load imbalance.
The Delta PQC Series SVG is also in modular structure, which adopted 3-level inverter topology with 12 pcs discrete IGBT and DC capacitor components and the Delta SVG system consists of one or several SVG modules and a display. There are two types of displays, one is Touch Panel Human Machine Interface (HMI), which is touch-screen type, and the other one is non-touch- screen type, call Liquid Crystal Monitor (LCM). SVG’s HMI or LCM can be shared with Delta APF modules. Each SVG module is an independent reactive power compensation system, and users can change the SVG rating by adding or removing SVG modules. According to the mounting type, Delta PQC series SVG can be divided into modular APF (rack mounting) and wall-mounted solutions.
Elspec’s power quality solutions compensate for full load reactive power demands in less than one network cycle. Their real-time compensation systems stabilise voltage, enhance PF, mitigate Harmonics and reduce voltage flickering & fluctuations. Utilising free transient switching technology through precise zero-crossing thyristor control, Elspec’s solutions enable quick problem identification, power factor correction and faster decision making. The result is smoother operation, better equipment protection and standard regulations compliance. Built for durability, Elspec’s solutions are designed for reliable performance over years of operation.
