There is a growing interest in electrical grid
connection of single unit Wave Energy Converters (WECs), as
well as the multiple units based Wave Power Plant (WPP)
applications. Due to the increasing integration of high power
converters in WPP, additional concerns on the harmonic current
mitigation of WEC device arise which requires the grid filter
installation. Furthermore, the identification and appropriate
mitigation of additional harmonics at the WPP level is needed, as
any inductances and capacitors of the WPP can interact with the
resonant frequency of the entire system and lead to detrimental
effects on equipment. The present paper focuses on the potential
harmonic studies of a realistic proposed WPP layout, in which
the system resonances are identified by performing the frequency
scan and modal analysis (HRMA) methods. The later technique
has the ability of determining the participation factor of each
bus, finding in this way the nodes in the system that have more
influence on the obtained results. In this way, the most suitable
nodes in which additional filtering solutions should be
implemented can be identified. |
