Power Quality Problems With the in-depth application of power electronic technology, the automation of the petrochemical industry has been continuously improved, and the nature of the load has also undergone qualitative changes. The increase of nonlinear and impact loads has brought about voltage flicker, three-phase imbalance, and excessive reactive power consumption. , harmonics and a series of ...
Current and voltage harmonics are often used interchangeably. At most places, only harmonics is quoted and whether the values pertain to current or voltage is not mentioned. The differentiation can be done on the basis of their origin. What is Total Harmonic Distortion? The current and voltage harmonics in a system are often expressed as Total Harmonic Distortion (THD). The total harmonic d...

Microgrids are designed to operate at a fundamental frequency (50 or 60 Hz). However, certain types of loads generate voltage and/or current harmonics that increase power system heat losses. These harmonic losses reduce system efficiency, cause apparatus overheating and increase power costs. Besides that, the Distributed Generation (DG) is expected to play an important role in future power systems...
