| Abstract: |
| Offshore substation is the key to offshore wind farm power energy transmission. A novel modeling method based on Markov process was put forward for reliability research of offshore substation electrical equipment. Firstly, operation condition of electrical equipment was divided in order to determine the two state Markov model. Secondly, through analysis of connection form of basic electrical element, its state transition probability matrix and a transition probability density matrix were established. The reliability model of major offshore wind farm substation equipment such as transformers, bus-bar, and cable was established based on Markov equation. The reliability index of the offshore wind farm substation systems was analyzed. Finally, on the basis of some offshore wind farm specific data, combining with the reliability model, the reliability index of the offshore wind farm substation system was analyzed. |
