    Introduction

    SVG Principle

    The principle of the SVG is very similar to that of Active Power Filter, as demonstrated in the picture below. 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 and compensating part of harmonic currents.

    Note: CT is a critical part of the SVG system, and it can be purchased by users themselves, following Delta’s suggestions on CT specification.

    SVG Structure

    Delta PQC Series SVG has a modular design, which adopted 3-level inverter topology with 3pcs modular IGBT and DC capacitor components, and the Delta SVG system consists of one or several SVG modules and a HMI display.

    SVG’s HMI 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.

     

    SVG Module and Cabinet Solutions

    According to cable terminal type, a modular SVG can be divided into two types:

    • Drawer type modular SVG (adding pluggable accessories on power cable terminals)
    • Mixed fixed type modular SVG (Power cables are fixed from rear side, Signal cables are fixed from front side.)

    HMI has two types:

    • 7’’ HMI
    • 10’’ HMI

    SVG modules and HMI panel can be embedded in Delta’s standard SVG cabinet or a customized cabinet. There are breakers, cable terminals and Surge Protection Device (SPD) in the SVG cabinet. Delta can supply IP30, IP42, IP54 or customized solutions.

    Wall-mounted SVG Solutions

    Delta’s Wall-mounted SVG can be installed on a wall, which is suitable for low rating applications, and wall-mounted type HMI can be installed on the wall-mounted SVG module, along with a mounting bracket to provide support and protection. Delta can supply IP30, IP42, IP54 or customized solutions.
