The scenario
An 18 MW biomass-fired extraction steam turbine generator supplies an 11 kV generator bus, steps up to 66 kV for utility interconnection, and feeds 400 V auxiliary loads including fans, pumps, and district energy equipment.
What is in this drawing
Read the decisions behind it.
01
Dedicated generator breaker isolates the STG while keeping the 11 kV bus energized
02
Step-up transformer connects the 11 kV generator bus to the 66 kV utility grid
03
Auxiliary transformer and 400 V bus supply house loads independent of the main generation path
04
Utility interconnection meter provides export/import energy accounting
Reusable for biomass, waste-to-energy, or combined heat and power plants with a prime-mover generator, utility interconnection, and auxiliary power distribution.
