Hazards of Phase Operation

1. Adding the active load of the generator will make the generator develop in an unstable direction, and it is easy to form unstable operation of the generator and even system oscillation.

2. Continue to reduce the excitation current of the generator, so that the generator phase depth is added, which may lead to the loss of excitation maintenance action of the generator or unstable operation of the generator.

3.Generator phase operation, stator current add, add stator heat; When the generator is in phase operation, the change ratio of flux leakage at the stator end increases, making the end heating the most severe, and the temperature of the generator stator coil will continue to rise.

4. When the generator is in phase operation, the generator outlet voltage drops, making the 6KV bus voltage drop. The high-voltage motor with low voltage maintenance will trip; The electrical equipment in operation, due to the bus voltage drop, current increase, resulting in equipment heating, long-term operation will damage the insulation of equipment.
