Electrical collector topologies for offshore wind power plants: A survey

This paper gives an overview of various collector topologies for offshore wind farms. A comparative analysis of different DC and AC collector system topologies for offshore wind power plant are presented. The advantages and disadvantages of collector system topologies in terms of cost, reliability and efficiency are discussed. The paper discusses various updated collector topologies like radial, single sided ring, double sided ring, star and hybrid AC-DC etc. in AC collector systems and series, parallel, hybrid and matrix interconnected topology etc in DC collector systems. At the end alternative topologies based on bypassing method for radial, double sided topology are explained.
