5.10 Reverse power protection of generator

5.10.1 Protection principle

Reverse power protection is used to protect steam turbine. When emergency stop valve is switched off

by accident or the unit protection operation closes emergency stop valve and exits breaker and does not trip,

generator will be operated as electromotor to absorb active power from the system. Tail blade of steamer

will probably overheat to cause destroy of steamer due to blast loss. Reverse power protection can have a

good protection role. Two sets of independent reverse power protections are equipped on large generating

unit.

Reverse power protection reaction generator absorbs active power from the system and reverse power

is blocked by TV breakage.



Voltage is from generator terminal TV and current is from generator neutral point (or generator

terminal) TA.

Tripping mode: signaling or tripping
