MPA-200B Power Plant Solution
ID/FD/PA Fan VFDCirculation PumpFGD/DeNOx4×1800kW
MARKET CONTEXT · POWER PLANT AUXILIARY DRIVES
Growing Demand for MV VFD in Power Plant Applications
60–70% of power plant auxiliary electricity is consumed by fans and pumps — the primary targets for VFD energy savings
Energy Efficiency Mandates: National policies require power plants to reduce auxiliary power consumption by 15–25% through VFD retrofit
FGD/DeNOx Compliance: Environmental regulations drive new FGD and SCR installations, each requiring 2–6 large MV VFD motors
Aging Infrastructure: Existing power plants upgrading from DOL/soft-start to VFD for improved process control and reduced maintenance
8-12 Large MV Motors -Fans + Pumps-
4,000-15,000 kW Total Drive Capacity
E-House solution consolidates all VFD equipment into a prefabricated, factory-tested package — reducing site installation time and interface complexity
APPLICATION SCENARIOS · FAN & PUMP VFD CONTROL
E-House Drives Power Plant Fans & Pumps
6 Target Motor Load Categories | 400-2,500 kW Motor Range per Unit | 6.6kV MV Voltage | 5-Step Power Flow: MV Incoming → MV Switchgear → MV VFD -AC-AC- → Output to Motor → Fan / Pump Load
ID Fan (Induced Draft)
1,000–2,500 kW · 6.6kV — Flue gas extraction, highest energy saving potential (30–45%)
FD Fan (Forced Draft)
800–1,800 kW · 6.6kV — Combustion air supply, energy saving 25–35%
PA Fan (Primary Air)
600–1,500 kW · 6.6kV — Coal pulverizer air supply, frequent load changes
Circulation Pump
1,200–2,000 kW · 6.6kV — FGD slurry circulation, high torque at low speed, 24/7 duty
Booster / Feedwater Pump
800–1,600 kW · 6.6kV — Feedwater booster, continuous duty with flow regulation
Condensate Pump
400–1,000 kW · 6.6kV — Condenser extraction, variable flow demand
