6 FAQs about [Harmonics of wind power and photovoltaic power generation]
What are harmonic sources in wind power plants?
For wind power plants generally harmonic sources can be listed as resonance harmonics, soft starter harmonics, converter harmonics, transformer & generators, D-statcom and HVDC systems harmonics , , . Harmonic sources and problems in wind farms are examined in more detail in Section 4.
What is a harmonic problem in wind power plants?
Another serious harmonic problem in wind power plants might occur when more than one wind power plant is connected to each other with PCC points as shown in Fig. 13 .a and when they are used at 80% nominal capacity. Harmonic problem arises when the third plant reduces its power capacity from 80% to 0%.
Do wind turbines emit harmonic currents?
A drawback of the use of power electronics is the emission of harmonic currents. Consequently, a systematic study on the emission from wind power installations is needed, which holds for individual wind turbines as well for complete installations. Wind power installations impact the harmonic levels through their emission.
How do wind power installations affect harmonic current and voltage distortion?
Wind power installations impact the harmonic current and voltage distortion in the grid in several ways. Individual turbines are an additional source of harmonic emission. Measurements on turbines and comparison with other sources show that the emission of the characteristic harmonics is small.
Why are harmonics a problem in a power plant?
Harmonics are one of the more common power quality issues presented by large WPPs because of the high switching frequency of the power converters and the possible nonlinear behavior from electric machines (generator, transformer, reactors) within a power plant.
Why are wind power plants harmonic injections?
Wind power plants are harmonic injections due to their linear force , . Sometimes harmonics arise as an important problem in wind farms. The source of harmonics might occur for various reasons. Basically, schematics of four different types of wind generators of the wind power plant (WPP) , are presented in Fig. 12.
