| 中文摘要: |
| 海上升压站是风电场电能传输的关键环节。针对海上升压站电气设备的可靠性研究，提出了一种新颖的基于马尔可夫过程的建模方法。首先对升压站电气设备的运行状态进行划分，确定其二状态马尔可夫模型，其次分析基本元件的连接形式，建立其状态转移概率矩阵和转移概率密度矩阵。在此基础上根据马尔可夫方程建立海上风电场升压站内主要设备变压器、母线,电缆等的可靠性模型，并分析了升压站系统的可靠性指标，最后根据某海上风电场的具体数据，结合所建立的升压站电气设备的可靠性模型，对此风电场的升压站系统的可靠性指标进行计算分析。 |

| 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. |
