Micro-Hydraulic Generating Equipment
Brief introduction on structures of the turbine-generator units
1. Low head and horizontal tubular turbine: the water enters into the runner through the fixed guide vane. The turbine can be directly connected with the generator by using the flexible coupling, or can be directly used to drive other equipment by using the belt pulley.
High head and vertical Turgo turbine: the turbine and the generator are directly connected and integrated into a whole unit. The nozzle needle is arranged at the inlet of the turbine to regulate the flowrate.
2. The generator: Three-phase AC synchronous generator is employed.
3. Comprehensive control panel: this control panel is supplied with the turbine-generator unit with the capacity between 8 – 100kw to control the Unit automatically. Such functions as acquisition and display of technical parameters, control of voltage and frequency, synchronization operation, protection of overspeed, overvoltage, short circuit and backup are integrated into this control panel. After the Unit being started, this control panel can automatically monitor the load fluctuation, maintain the load balancing and keep stable voltage and frequency of the Unit, so as to ensure smooth operation of the Unit.
With the salient features of compact size, light weight, simple structure, reliable operation and easy installation and utilization, Turgo turbine connected with three-phase permanent magnet AC synchronous generators with the capacity between 6kw and 30kw is most suitable for generating electric power for small load consumers in mountainous areas, and appropriate for individuals to purchase, install, manage and use.
The vertical shaft micro-hydraulic turbine and generator unit is assembled with vertical shaft turbine and permanent magnet synchronous generator. The turbine will be installed into the volute chamber at the site. With the characteristics of compact structure, attractive appearance, small size, light weight, high efficiency, without excitation device and casing made from cast iron, it is with wide applicability and reliably-operational capability, and easy to install, maintain and use.
