Abstract:

The power supply of oil drilling rig has drawn more and more attention with its prosperous development. In order to improve the power supply reliability of oil drilling rig, the PV/storage/diesel system was adopted to replace that of single diesel generator. Firstly, the power supply topology of oil drilling rig was established, and the corresponding units were modelled. In addition, the economic model of PV/storage/diesel system was constructed. The constraints of energy storage state of charge (SOC), storage power and diesel generator power were considered to realize the economic operation of the system. Finally, an example was given to analyze the effectiveness of the operation control strategy. The research results can provide a reference for the power supply mode of oil drilling rig.

Key words: oil drilling rig, PV/storage/diesel power supply system, operation control strategy
