 What happened if generator rotate at reverse power?



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
