PowerFlex 7000 - Success Stories

• Project Plzeňská Energetika

• Feed Water Pumps

• Project Povodí Odry

• Synchronization of the generator to the grid


Plzeň

Project Plzeňská Energetika - Feed Water Pumps

• Heating and power station in Czech Republic

• Synchronous transfer for 2 existing motors

• PF 7000 1,6MW / 6,0kV

• Second PF7000 ordered

• Limited space for instalation


Technical Data (depending on the application)


• Motor data

• Load data

• Mechanical data

• Grid data

• Most of the time we are getting the SLD from the existing or new

configuration

• SLD for the new configuration from the existing configuration

• Quote

• Project management

• Delivery and Startup

Receiving the customer request


Customer meeting to have a common understand


• Visiting the application and planed location of the MV installation

• Conclusion

• Standard solution with PF7000

• One VFD for two motors

• Special function - synchronous transfer

Analyzing of the request to understand the needs of the customer


Customer Single Line Digram Implementation of the new equipment


Working out the solution modification of the Single Line Diagram


Providing the technical data of the equipment


• Dimensions

• Heat losses

• Floor load capacity

• Cableways

• etc.

Working the possible arrangement of the equipment in planed e-room

„Open mind – limits are only in head“

Project Povodí Odry

• Hydroelectric power station in Czech Republic

• Generator synchronizations to the grid

avoiding transition currents and flicker

• Synchronous generator 2,65MW / 6,3kV

• PF7000 18 pulse, 895kW

• Service and maintenance contract

Slezská Harta
