摘要

An innovative approach has recently been adopted at a mini hydro scheme in New Zealand, based on a motor developed for washing machines. This could have applications as a low cost solution for other small and micro schemes in isolated areas. My wife and I are part owners of a 1000 kW hydropower scheme in New Zealand. The dam and intake need a supply of electricity for a radio transmitter and PLC and infrequent operation of valves and the screen cleaner. The main load is the electronic equipment that takes a continuous 6 W. It was too expensive to bring a cable from the powerhouse 1400 m away, so a 120 W solar cell installation costing about $US 2500 was installed. In spite of having several days of battery backup, it failed to keep the batteries charged in the winter when it can be cloudy for many days. We decided that at least 360 W of cells would be needed to solve the problem. This was going to be expensive so I started looking for alternatives and came upon Michael Lawley, a New Zealand engineer who has developed a range of micro hydro units and wind generators based on permanent magnet electric motors recycled from scrapped 'smart drive' washing machines developed by Fisher and Paykel, a New Zealand company.
