Starlight generator

Generator loss of excitation fault means that the excitation current provided by the excitation system suddenly disappears completely or partially. After the synchronous generator is out of magnetic, it will be transferred to the asynchronous running state, and the reactive power will be absorbed from the original reactive power conversion. The causes of generator loss of magnetism fault are: generator rotor winding fault, excitation system fault, automatic demagnetization switch trip and circuit fault. The effect of generator loss of excitation on the system: 1. Low-excitation and magnetic-loss generators absorb reactive power from the system, causing the voltage of the power system to decrease. If the reactive power reserve in the power system is insufficient, the voltage in some adjacent points in the power system will be lower than the allowable value, which destroys the stable operation between the load and each power supply, and even collapses the power system voltage. ...
