Why adjust the power factor of a generator? 1. When the generator is running, the power factor is too high, that is, the reactive power is too low, which reduces the reactive power margin of the system and affects the steady-state stability of the generator. Although the economy is improved, in the long run, this is in exchange for an increased probability of accidents. Once an accident occurs, th...

Power factor is an important technical indicator of the power system. It represents the ratio of active power to apparent power in an AC circuit. This ratio is usually expressed as a cosine function (cosφ). The size of the power factor reflects the energy utilization efficiency of the power supply output. If the power factor is too high, that is, the reactive power is too low, it will reduce the r...

Zero sequence current, known as residual current or triplen harmonic current, is a phenomenon that occurs in electrical systems due to the presence of unbalanced loads or nonlinear loads. The primary reason for the presence of zero current is unbalanced loads. In a three-phase power system, the loads are ideally balanced, meaning that the three phases draw equal currents. However, in practical sce...
