This paper attempts a detailed comparison of some of the solutions for the black start of the Offshore Wind Power Plants with Diode Rectifier based HVDC transmission. The major challenges and control requirements to ensure the black start operation are explained following a brief review of the existing capabilities of wind generators. The various solutions surveyed as part of the study are presented along with a detailed comparison. Moreover, a case study is simulated, supported by calculations to highlight the power requirements of the offshore grid during black start, enabling further assessment of the black start solutions discussed.
