Grouping Capability The APS has the ability to configure up to four groups of C60 C65 MicroTurbines where one group is a Stand Alone configuration and the other three are Grid Connect configurations The Stand Alone group can be a Stand Alone only configuration or it can support a dual mode system where it includes any combination of the MicroTurbines from any of the three Grid Connect groups When configured for a dual mode system the active Grid Connect groups will run as set up and in the event of a power outage will switch over to Stand Alone operation as configured for the Stand Alone group setup Clearly this allows for a great amount of flexibility in the operation of the MicroTurbines when a power outage occurs Each Grid Connect group acts as a separate virtual MicroTurbine that can then have completely independent operating modes compared with the other Grid Connect groups This allows the APS to control groups of MicroTurbines in a building that have separate operational goals and or separate locations For example six units might be set up as a back up group for a computer room five units might be set up as a facility electrical load following group and two units might be on the other side of the building running in Grid Connect heat recovery mode for process heating or air conditioning as illustrated in Figure 2 480023 Rev A June 2007 Page 6 of 16 Capstone reserves the right to change or modify without notice the design spec

5. operating control mode to function which can be very helpful in troubleshooting facility issues Care must be taken to not take too many units away from the controller when operating in an automated control mode as this may result in unexpected performance of the controller and system as a whole ICHP Thermal Load Following Compatibility The APS acts as a master for each group and ICHP units can be set up under each group to operate in electric priority or thermal priority modes The APS provides additional flexibility when setting up thermal recovery systems compared to MultiPac systems where a MicroTurbine is the master Refer to the C65 ICHP Application Guide 480014 for additional information about how to set up thermal recovery systems Electric Priority with Thermal Tracking For electric priority mode the APS provides the electric load following logic and controls power output of each MicroTurbine accordingly The thermal output of each ICHP MicroTurbine s heat recovery module is determined by the position of its exhaust diverter valve which is controlled by temperature measurements and temperature setpoints These temperature measurements and setpoints can be done individually at each MicroTurbine local or as a group through the APS Measurements and setpoints are independent and can be set for either APS or local MicroTurbine operation e g the temperature setpoint can be controlled by a user set value in the APS while the actual me
6. temperature measurements and temperature setpoints must be done at the APS since the APS is providing the control commands to each ICHP MicroTurbine in the group to adjust its electric power output to maintain the desired temperature As noted above the temperature measurement input to the APS can come from a variety of sources and may require some custom PLC programming Likewise the temperature setpoint in the APS can come from a variety of sources including manual user input or dynamic data read from a building management system where the APS is acting as a Modbus slave 480023 Rev A June 2007 Page 8 of 16 Capstone reserves the right to change or modify without notice the design specifications and or contents of this document without incurring any obligation either with respect to equipment previously sold or in the process of construction Capstone Turbine Corporation e 21211 Nordhoff Street e Chatsworth e CA 91311 USA Advanced Power Server APS Technical Reference Transition from Grid Connect to Stand Alone Operation Care must be taken when setting up groups that include Dual Mode units that will switch between operating modes The APS allows each group to have its own thermal load following control schemes as defined above However all switched ICHP units must use the same temperature measurement and setpoint scheme for both Grid Connect and Stand Alone operation For example if the thermal priority mode is chosen for Grid
7. Connect operation for ICHP units in groups 2 3 and 4 the APS temperature measurement and setpoint must be the same if some or all of these ICHP units are also in group 1 for Stand Alone operation If the heat recovery system design requires the Grid Connect groups to operate with different temperature measurements and setpoints this can be accomplished by using electric priority with local thermal load following control at each MicroTurbine for both temperature measurement and setpoint This allows the selected Grid Connect ICHP units in each group to transition to Stand Alone without changing the thermal operating scheme but maintains the desired independent thermal load following operation Note that thermal recovery capacity from ICHP units operating in Stand Alone will likely be less than when they are operating in Grid Connect mode Dual Mode Compatibility A single dual mode controller can be connected to the APS to operate a single group of Stand Alone MicroTurbines in the event of a power outage The dual mode controller allows the systems to transition to a Stand Alone power generation system automatically within 10 seconds if the grid power fails as the APS is compatible with Capstone s Fast Transfer functionality Note that Fast Transfer capability is only provided in C60 C65 software version 4 50 and higher When combined with a small UPS system to cover the load during this fast transfer 10 second window the user can build an uninterr
