Solar power station generator main protection

What is generator protection scheme?

Generator protection scheme. At substations, the lines, interconnecting transformers, and reactors constitute major static power components crucial for system operation. The transformer, depicted in Fig. 6, is a localized element featuring two sets of delicate windings that may directly or indirectly experience fault currents.

What are the problems with a generator protection system?

Another difficulty with the generator protection system is the fact that, unlike other equipment, opening a breaker to isolate the defective generator is not enough to prevent further damage, since the generator will continue to supply power to its own fault until its field excitation has been suppressed.

What type of protection does a generator have?

These include unit differential and zone-1 distance relays. Generator transformers and transmission lines are also protected with two independent main protection designed to clear the fault with in 100 ms. Distance-based backup protection is provided for the protection of transmission lines through Zone-2 and zone-3 operations.
