Diesel Generator Tech

When the active load is full, the power factor is too high, that is, the reactive power is too low, reducing the reactive power margin of the system, which will affect the stability of the generator. Although the economy is improved, in the long run, this is in exchange for increasing the probability of accidents. In the event of an emergency, the generator may not be able to withstand small disturbances or oscillations, may be out of step. In addition, the low reactive power will cause the generator terminal voltage to drop, which will affect the auxiliary power. The current drawn by the motor rises, causing the voltage to be lower, creating a vicious circle that may cause the entire system to lose its stable operation and collapse. 1. Too high power factor will also increase the chance of the generator phase operation, and make the generator end heat easily. 2. If it is too low, the reactive power is too high, the excitation current rises, the rotor winding tempe...
