The NuSTREEM concept of hydro power generation is to provide remote access and control for isolated installations and to allow the minimal support staff possible. The maintenance and support can be provided through monitoring “exceptions” or “notifications” that initialize activity rather than routine periodic overview.
The NuTECH Controller provides an automated intelligence that can be accessed remotely. This provides management of the asset, or family of assets, through a central location not necessarily co-located with the site.
Further, we are providing overall access to the site through remote access to the main PLC. This allows overall site characteristics to be accessible.
The modularity of the containerized system helps in providing a common element that operations staff has to “learn”, thereby supporting a quicker and easier understanding of the system for ease of maintenance of the repeated design.
It also allows the site owner to store the common component, the turbine, in inventory and easily replace turbines requiring maintenance, refurbishment, or other non-routine events. The owner then has the option to send the original back to the factory. This provides a simple maintenance plan without specialized capabilities at the site.
This NuCONTAINER system is easily transported to the hydro site using standard rigging methods. In addition, the container, including three turbines, could be lifted by air and placed in remote locations.
The basic construction of the container begins with a standard forty-foot shipping container (assuming three turbines; twenty foot for a single turbine). Reinforcement to the floors and the walls are provided to ensure structural integrity. Turbines are installed at the factory with all accessories.
Bulkhead style connections are provided at the walls of the container to allow connections to the penstock and draft tube.
Access to the interior of the container is through the end doors as well as through a top hatch or side wall access door depending on the quantity of turbines housed.
Passive ventilation is provided for most locations. For hot climates, mechanical systems can be utilized to regulate the internal air temperature and humidity.
The container will have a power panel as shown below that feeds electric power to the controls distributed in various panels and enclosures. This configuration will be common across containers with the one exception being the number of NuTECH Controllers will be consistent with the number of NuTURBINE’s housed in the NuCONTAINER. Ancillary lighting is provided to ensure the internal areas are illuminated for routine maintenance or other required access to the turbines.
