DPS-H separate compensation

  • No harmonic is generated, no harmonic is amplified and the odd harmonic orders lower than 13th can be filtered.

Stepless adjustment

  •  DPS-H can realize dynamic stepless adjustment without over compensation and short-compensation

Modularized product design

  •  DPS-H adopts modular product design
    and cabinet installation.
  • It features convenient engineering design
    and installation

Power factor, Three-phase unbalanced and Loworder harmonic synchronization control

  • Mainly compensate power factor and threephase unbalance
  • Support low-order (3, 5, 7, 9, 11 orders) small capacity (50% rated power) harmonic compensation

Resonance avoidance

  •  DPS-H is a current source device which avoids resonance phenomena in mechanism

Multiple compensation applications

  • DPS-H separate compensation
  • DPS-H separate compensation

The compensation capacity of DPS installed capacity.The compensation capacity of SVG is installed capacity.The installed capacity of
traditional compensation device is usually more than actual capacity		Capacity characteristic
The DPS floor space is always 50% of other reactive compensation type which has same capacity, even smaller.The SVG floor space is always 50% of other reactive compensation type which has same capacity, even smaller.LargeSpace

Operating principle

 DPS-H Advanced Generator conducts real-time monitoring to load current through external Current Transformer (CT) and detects reactive components and harmonic from load current through the calculation of internal DSP, then transmits PWM signal to internal IGBT. Conforming reactive current and low-order harmonic Acurrent are generated by inverter with control settings to achieve reactive compensation and control harmonic.
