First of all, it must be clear that the generator is only one component of the generator set. Power generation equipment that uses superheated steam is called a steam turbine generator, consisting of a steam turbine and a generator. The steam turbine uses the thermal energy of the steam to convert the kinetic energy of the rotor, which then drives the generator rotor to produce electricity.
As for what superheated steam is used for, you first need to know two concepts: saturated steam and superheated steam. Simply put, superheated steam is reheated based on saturated steam. The characteristic of saturated steam is that its temperature is at the boiling point and it will condense into water when cooled (for example, water vapor at 100°C under standard atmospheric pressure is saturated steam) . But superheated steam won't. OnceOnce the superheated steam has worked and cooled, it will still be a gas. This effectively protects the steam turbine, as the impact of condensation water is very detrimental to the safety of the unit.
For more details, you need to look at thermodynamic engineering knowledge. I'm just speaking in general terms.
PS: I design power plants.
High vibration, low vacuum, high bearing temperature, high oil temperature, water impact, low pressure oil, turbine overspeed, generator throw load, etc. . Generally speaking, if the operating parameters exceed the operating parameters, the load will be reduced. If it still fails, the turbine will be decoupled and stopped. If the parameters change suddenly, the turbine will be stopped directly. The system has many protection settings and usually shuts down automatically.matically. Additionally, if the generator catches fire, it must be uncoupled but not shut down. It must maintain a certain speed to prevent the large shaft from bending unevenly from the heat.
