Stepless compensation and multi-step compensation are two different approaches used in power system compensation to mitigate the effects of reactive power and voltage fluctuations. Stepless Compensation: Stepless compensation, also known as continuous compensation, involves the use of a continuously adjustable reactive power compensator to regulate voltage and control reactive power flow. The most...
The peak and effective value of harmonics When discussing the peak of harmonic currents, it's essential to first understand the fundamentals of harmonics. The effective value (RMS value) of a harmonic describes the average power of the harmonic component over one period, reflecting the equivalent extent to which the harmonic causes heating effects in the system. However, the peak of a harmonic (th...
