Hybrid UPS System Operating Modes
This section explains the different operating modes of the Capstone Hybrid UPS
MicroTurbine and how the system transitions between operating states. A description of
the major system components is provided to clarify the terminology and understanding of
how the system works.
Major System Components
The C65 Hybrid UPS system is based on the Dual Mode C65 MicroTurbine, with the
addition of a second Load Control Module (LCM) to allow load power to be provided by a
utility grid, the turbine generator, or both. Figure 2 shows the major components in a single
