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 relationship between capacitors and harmonics is very close, especially in power systems. The use of capacitors can affect the generation and propagation of harmonics, and are also easily affected by harmonics, leading to reduced performance or damage. Harmonic amplification In the power system, capacitors have a lower impedance to harmonics, so harmonic currents tend to flow through th...
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...
The harm of harmonics to power capacitors mainly includes the following aspects 1. Overcurrent and Overload -Harmonics can cause distortion of voltage and current at the capacitor terminals, especially at specific harmonic frequencies, where capacitors resonate with inductive components in the system, resulting in significant amplification of harmonic currents. Excessive harmonic current causes th...
