This paper presents a summary of the most important issues with respect to harmonics and resonances within wind power plants. An introduction is given to provide an overview of the various power quality related issues encountered when designing, commissioning, or operating a wind power plant, as well as typical characteristics of the components associated with wind power plants. The many variables,...

This paper considers the harmonic supply voltage evaluation of non linear distorted loads, such as diode bridges, arch furnaces and so on, connected to medium voltage cable line. The connection to the MV grid allows a cost reduction of the measuring and protection apparatus, but it introduces problems such as the low short circuit power that can cause a high harmonic voltage distortion. The paper...
This paper presents the harmonic study and evaluation when low-voltage adjustable-speed drives (ASDs) are employed in an industrial plant. The procedure of harmonic study is proposed in step-by-step fashion, starting from the analysis of input current characteristics of ASDs. The single-tune filter design with the parameters of the actual network is reviewed and discussed. The evaluation of harmonic...
Subsea cable applications for the offshore power distribution systems create technical challenges in the system design, operation and maintenance. Harmonic parallel resonance introduced by subsea cables is one of the main concerns. In this paper, parallel resonance is investigated for an offshore distribution system with lengthy subsea cables on four interconnected platforms. Variable frequency drives...
