The type selection of the oil pressure unit in Nam Ou 6 Hydropower Station of Laos is introduced.Chinese na-tional standard for governing system of hydraulic turbine and technical requirements for hydropower stations in small pow-er grids are adopted as the selection criteria.Volume of the oil tank in the oil pressure unit is estimated with the Boyle's Law and engineering experiences, which satisfies the operational requirement of the hydropower station.Also, the ca-pacities of the oil pump and the electrical motor are determined.Redundancy design is used for the whole oil supply sys-tem, in which the energy saving dual oil pump, dual electrical motor, and dual retraction redundancy combination valve are adopted.And, high quality imported products are selected for the main automatic components and control devices.
