Capstone Turbine Corporation 21211 Nordhoff Street Chatsworth CA 91311 USA Technical Reference: Dual Mode System Controller (DMSC) MultiPac Operation with Fast Transfer The descriptions of operation above show a single MicroTurbine. When connecting several MicroTurbines in a MultiPac, the control wiring goes to the master unit, which in turn coordinates operation of the subordinate units. It is recommended that a second MicroTurbine be wired in parallel with the master so that it can be manually programmed to act as the master when the master unit is taken out of service. Note that Fast Transfer can also be used with the Capstone Advanced Power Server (APS), and control signals must be wired into the APS as the master. Since the Master MicroTurbine must receive the input signals, take the appropriate actions, and then communicate to the subordinate units, the transition time to Stand Alone mode for a MultiPac may take slightly longer than the transition times indicated in the preceding figures, depending on the number of MicroTurbines in the MultiPac, but will still typically transition in less than 10 seconds, if the Fast Transfer Delay time is set to its default value of 0. Refer to the C60/C65 MultiPac Operation Technical Reference (410032), or the C200 Technical Reference Guide (410066) for additional details. Combined Heat and Power (CHP) Operation with Fast Transfer The C60/C65 MicroTurbine can be programmed to operate is several heat recovery modes. If set to Electric Priority (with thermal tracking) or Thermal Bypass, there will be no change in the operating mode when switching between Grid Connect and Stand Alone modes of operation. If the MicroTurbine is set for Thermal Priority for Grid Connect operation, it will automatically switch to Electric Priority (with thermal tracking) when operating in Stand Alone or Hot Standby modes, and switch back to Thermal Priority when operating in Grid Connect mode. Refer to the C60/C65 Integrated CHP Technical Reference (410043) and Application Guides 480007 and 480014 for details about C60/C65 CHP operation. A C200 MicroTurbine configured for CHP experiences no change in operating mode related to the transition between Grid Connect and Stand Alone. Refer to C200 Heat Recovery Module (HRM) Technical Reference (410070) for details about C200 CHP operation. External Protective Relay Operation with Fast Transfer An external protective relay may be required in some applications to meet local utility interconnection requirements, or to provide additional protective functionality. For example, reverse power protection may be required to prevent inadvertent export under certain situations. For these requirements, the external protective relay should simply trip a circuit protective device that is located between the utility grid and the DMSC. Alternatively, connect the external protective relay to the CPR input terminals in the DMSC. The MicroTurbine and DMSC will then respond to the loss of voltage at the input terminals to the DMSC, as shown in Figure 31. This will force a transfer to Stand Alone operation, even though the UVR in the DMSC did not sense a utility fault. When utility voltage is returned to normal, the circuit protective device can be re-closed, which will re-establish utility voltage at the DMSC input terminals and cause the DMSC’s UVR to close the remote disconnect device. Note that the MicroTurbine will then monitor the utility voltage for the preset reconnect time prior to reconnecting in Grid Connect mode, in accordance with UL 1741 requirements. 410071 Rev.
