inconsistent load will cause steam turbine hunting.
Governor hunting or surging is a problem that causes the engine to constantly speed up rapidly and then slow down rapidly.
Hunting, fishing and drinking ....LOL

According to " Outdoor Power Equipment By Jay Webster",Governor hunting or surging is a problem that causes the engine to constantly speed up rapidly and then slow down rapidly.
In large turbines, a valve controls steam flow to groups of nozzles. The number of open valves controls the number of nozzles in use according to the load. A bar-lift or cam arrangement operated by the governor opens and closes these valves in sequence. Such a device is a multi-port valve. Using nozzles at full steam pressure is more efficient than throttling the steam.
When the steam turbine can not maintain its selected or designed speed.Type your answer here... Speed fluctuating from low to high speed continously.
Governor
governor senses the speed of spindle of engine and controls the mechanism of opening and closing of throttle valve
It could overspeed and wreck itself-but there are emergency stop valves as well as the governor, so it is unlikely.
