Rehabilitation of Turbines at the Ohakuri Hydro Power Station

摘要

Ohakuri Hydro Power Station in the North Island of New Zealand is the second of nine hydropower stations on the Waikato River owned and operated by Mighty River Power Limited. The Ohakuri plant contains four 28 MW Francis turbines designed and built by Dominion Engineering. The turbines were commissioned in 1961 and were operated through to 2011 without any major rehabilitation work. All four machines have had new turbine equipment installed with the fourth and final machine completed in April 2014. The main project objectives of modernizing the turbines and increasing performance have been achieved.
