DRPCE

DUBAS designs and manufactures Dynamic Reactive Power compensation systems for Traction Substations (TSS). The power factor of the substation suffers from dynamic load pattern due to a number of trains getting in and out of the substation power loop based on train movements. DRPCE is a dynamic PF and power quality improvement system, capable of both inductive and capacitive compensation instantaneously.

Dubas’ DRPCE systems are based on dubas ePFC philosophy and is an IGBT based PWM current generator. DRPCE system is a hybrid combination of several ePFC panels and HT capacitor bank to reach desired compensation capacity. Dubas DRPCE systems are approved by RDSO and are in compliance to RDSO specifications. Dubas offers the DRPCE system on a turnkey basis including HT to LT conversion transformer, HT capacitor, Reactor and all protection systems along with Dubas range of IGBT based panels.

FEATURES:

• IGBT based PWM current generator technique with DSP based digital control, seamlessly parallelable.
• Dynamic system to maintain input PF near unity irrespective of the load dynamics.
• Can be built to reach several MVAR ratings and offer most cost economic solution through Hybrid model in combination with existing / new HT capacitor banks.
• Compensates both Inductive and Capacitive reactive power.
• Avoids danger of over compensation and resonance.
• System is expandable by adding incremental rating panels in parallel with the existing DRPCE panels.
