Reliability assessment of offshore oil platform power system based on state enumeration method

Based on the state enumeration method, a reliability evaluation method for offshore platform power system is proposed in this paper. Firstly, the reliability model of land-based components and the modelling method of the system are introduced. In reliability evaluation, all fault states are generated based on state enumeration method, power supply circuit sets are identified based on depth-first algorithm. The effects and losses of multiple faults are calculated based on platform maintenance capability, and fault time and load-loss time are separated and counted. Finally, taking an offshore oil platform as an example, the outage table of the system is generated, and the reliability index of the system is obtained, which verifies the effectiveness and accuracy of the method proposed in this paper.
