Enclosure
The MicroTurbine standard enclosure is designed for indoor and outdoor use, and is
certified to NEMA 3R - rainproof.
Hybrid UPS Functionality
The C65 Hybrid UPS MicroTurbine can operate in several modes:
•
UPS Mode – in this operating state, the Hybrid UPS system takes power from the
utility and provides conditioned output power to the load, similar to a traditional
double-conversion UPS system.
•
High Efficiency Mode – in this mode, the C65 turbine generator provides power to
offset the need for utility input power. By utilizing the microturbine’s clean exhaust
energy for heating or absorption cooling, extremely high energy utilization is
achieved to reduce operating costs, reduce net energy consumption, and reduce
overall emissions of greenhouse gas and criteria pollutants.
•
Emergency Mode – if utility power becomes unavailable, the Hybrid UPS system will
continue to provide power to the critical load using its external energy storage. The
turbine generator will automatically start to cover extended outages.
The Hybrid UPS system output will maintain synchronism with the utility grid whenever a
stable grid is available. A full description of the modes of operation is provided in the
Hybrid UPS Operating Modes section below.
UPS Controller
Capstone Hybrid UPS systems are designed to be controlled by an external accessory called
the UPS Controller. The UPS Controller acts as a master, providing control commands to each
Hybrid UPS system, reading performance and diagnostic data from each system, and acting as
the user interface. The UPS Controller can manage up to 10 Hybrid UPS systems, and
operates all connected microturbines as a single power generation source. Additional details
are provided in the Operating the Hybrid UPS System section below.
MultiPac Power
Capstone Hybrid UPS MicroTurbines can be installed in groups of up to 10 units using
Capstone’s UPS Controller as a master. The UPS Controller operates all connected
microturbines as a single power generation source. This MultiPac capability features a
single control point and synchronous voltage and frequency output for all units. Individual
MicroTurbines share power, current, and load on both a dynamic and steady state basis.
Integrated Combined Heating and Power (ICHP) Option
The Integrated Combined Heating and Power (ICHP) option allows the user to realize the
benefits of usable electrical and thermal power from a single fuel source. The Hybrid UPS
ICHP system provides high efficiency on-site power generation in conjunction with local
utility power. The heat offsets or replaces local thermal loads such as space heating,
industrial process hot water, or to drive an absorption chiller.
