8. Problems with Traditional & PLC Based System
• Many Components –
• Reduces Availability and increase maintenance of System
• More Wiring and hence more copper loss and reduce reliability
• More time in commissioning.
• Difficult in fault finding and assigning the responsibility
• More Spare parts inventory.
• Standardization
• PLC Programs are programmer specific and site specific and no standardization for operation.
• Difficult to operate and maintain.
• Require complete modification in software while adding new unit or power plant expansion
• Multiple Suppliers
• Difficult to coordinate and commission the system.
• Fault finding and diagnostics
• Long term Service & Support
• Frequent absolution of components and no long term service and support

9. Modern Controller - Delomatic 400 Hydro

10. Advantages of Modern DEIF Controllers
• Integrated system increases the reliability and maintainability.
• Fast reaction to events (internal interaction between functions), no data
transfer delay time between different units
• Reduces risk of wiring problems compared to components solution
• Reduces panel space requirement (footprint on base plate)
• Integration of control functions within one unit secures a bumpless
transition between control modes.
• Only three modules as spares for complete system.
• Single supplier, no problems with defining areas of responsibility

34. GPC -3 Hydro – Micro Hydro Turbine Controller
GPC 3 can be used for Francis or Kaplan turbine generator
with one speed control valve/wicket gate, controllable by
relay output UP/DOWN signals.
•Start and stop turbine
•Speed control
• ELC.
•Synchronise generator
•Fixed power operation
•Water level control with automatic start and stop

35. GPC -3 Hydro –Electronic Load Controller
Speed/Frequency control is done thru
Blast/Dump Load Control which will
increase/decrease in accordance with
the Governor Regulation output (i.e 4-
20mA) given by GPC-3 Hydro controller
to maintain nominal frequency set-point
of 50Hz.
The Governor Output is usually set as
•At 4 mA out put Dump/Blast Load = 0%
of Total Dump Load
•At 20mA output Dump/Blast Load =
100% of Total Dump Load
Both the Gensets will work in Active
Power (P) Load sharing mode and
maintain constant frequency of bus bar
