Objectif To develop a compact cross-flow turbine generator set with an electronic load controller suitable for the range 10 - 1000 kW.The project involved the rehabilitation of the hydroelectric plant at Certosa di Pesio (CN) through the replacement of the existing electro-mechanical equipment with a compact hydro-generator fitted with an electronic control system.The plant operates on an isolated grid and consequently is equipped with a synchronous generator.The control system regulates the generator frequency, and functions by switching in and cutting-out load resistors in order to compensate for the user variations and to maintain the load on the generator itself constant.The turbine in use is of the Cross-Flow type, in which the output can be limited to 20% of its nominal capacity. The compact nature of the group has allowed the installation time of the hydro-generator to be kept to a minimum. In addition, its simple operation also allowed the user personnel to be trained in just a few hours.During the inspection and subsequent commissioning phases, the machinery produced the required performances: the frequency variation was kept to a minimum and only lasted for a few seconds, even in the presence of sudden load variations.This technology is characterized by two important aspects: standardization of the turbine geometry and the electronic speed regulation.The first characteristic allow mass produced machines to be constructed and used for different hydraulic loads and capacities; the second characteristic allows the same regulator to be used for machines of different power rating.Rehabilitation of a microhydro power station, incorporating a compact turbine generator set together with a novel load controller system.An old 15 kW Francis turbine and auxilliaries has been replaced by a 30 kW cross-flow turbine and associated electrical equipment. Most of the original intake works and tailrace have been retained. Technical Data : Head 9.9 metres Flow 400 litres/sec Output 30 kWAll energy produced by the power station is used to supply a large part of the electricity requirements for the adjacent monastery (now a missionary institute), which also owns and operates the site.
