Generator leading phase operation

The leading phase operation of generator refers to the stable operation state in which the generator emits active power and absorbs reactive power. The so-called leading phase operation refers to the stable operation state in which the generator emits active power and absorbs reactive power. Its essence is a stable synchronous operation with low excitation. In this state, the stator current phase is ahead of the voltage phase. How much active power is allowed to be emitted and how much reactive power is absorbed during leading phase operation depends on the type, structure, cooling mode and capacity of the generator.
