Answer: b
Explanation: The turbo alternators are one category among the synchronous machines. They are driven by the steam turbines. The speed of the turbo-alternators is 1000 MW.
Turbo-alternators, also known as turbine generators, are specialized electrical generators used primarily in power plants to convert mechanical energy into electrical energy. The rating of a turbo-alternator is essentially the maximum electrical output it can deliver under specific conditions. This rating is usually expressed in megawatts (MW) or, for smaller units, in kilowatts (kW). The range of ratings for turbo-alternators varies widely, from as small as a few megawatts for small or medium turbines to several hundred megawatts for large-scale installations used in nuclear or coal-fired power plants.
The exact rating of a turbo-alternator depends on various factors, including the design, the size of the turbine, the steam pressure and temperature, and the efficiency of the system. In large power plants, turbo-alternators can have ratings exceeding 1000 MW. For instance, modern nuclear power plants often use turbo-alternators with ratings between 500 MW and 1300 MW. Coal-fired power plants might use turbo-alternators with similar or slightly smaller ratings, while gas-fired plants and smaller renewable or distributed generation facilities would typically use units with lower ratings.
It’s important to select a turbo-alternator with a rating appropriate for the specific application and anticipated load to ensure efficient and effective power generation.
