What happened if generator rotate at reverse power?

atOptions = {
'key' : 'bb50abd8651834037402f57330168d33',
'format' : 'iframe',
'height' : 50,
'width' : 320,
'params' : {}
};

ANSWER: When the generator becomes a motor, the turbine
will become its load. In the absence of steam flow, the turbine blades will be
spinning in air, and can overheat, potentially causing damage to the turbine.

In the case of a diesel or gas turbine driven generator,
motoring (another term for a power reversal) is not likely to cause damage. In
fact, some gas turbines are designed to intentionally motor for a few seconds
as part of their shutdown sequence. Gas turbines operate at much higher
internal temperatures than steam turbines (fuel combustion actually takes place
inside gas turbines), and in that case a few seconds of motoring will help
eliminate internal heat and prevent a temperature spike that could damage the
turbine.......REAhttps://www.effectivegatecpm.com/x7q17tzr?key=30b85378b8aa56f316060007c5ccbd7dD MORE
