Reliability Evaluation of Offshore Oil Platform Power System

This paper presents a method for reliability assessment of offshore oil platform power systems. Firstly, according to the environment and fault factors of the components on the platform, the reliability model of each offshore component is established. In order to evaluate the reliability of different types of platforms, a multi-state equivalent generator set model is established. Secondly, the breadth-first algorithm and Dijkstra algorithm are combined to calculate the power loss under the current state of the system in the state evaluation. Based on the reality of offshore platform, the Preferential trip sequence in EMS system is used to replace the load shedding result, which improves the accuracy and practicability of evaluation of offshore platform project. Finally, a platform in an oil field group in China is taken as an example to verify the accuracy and validity of the proposed method.
