Capstone Turbine Corporation 21211 Nordhoff Street Chatsworth CA 91311 USA Technical Reference: Dual Mode System Controller (DMSC) DMSC OPERATION When the utility voltage is acceptable, the DMSC will close the remote disconnect device to connect the MicroTurbine and protected loads to the utility. If the MicroTurbine Start Input is configured as REMOTE, the unit will act as a standby generator and will never start in Grid Connect mode. The MicroTurbine will periodically charge the batteries using power from the utility. If the MicroTurbine Start Input is configured as GC USER/SA REMOTE, the unit will start and dispatch power in Grid Connect mode according to the settings for User Start, User Power Level, Time of Use, and Load Following. The MicroTurbine will periodically charge the batteries using power from the grid or from the engine if the MicroTurbine is operating. When a utility outage occurs, the DMSC will open the remote disconnect device to isolate the MicroTurbine and protected loads from the utility and will automatically dispatch the MicroTurbine to start in the Stand Alone mode, regardless of the Grid Connect dispatch control settings. Grid Connect-to-Stand Alone Transition The following sequence occurs during the automatic transfer from Grid Connect mode to Stand Alone mode. 1. The utility voltage is acceptable. The Undervoltage Relay (UVR) in the DMSC is not tripped. The DMSC POWER switch (S1) is set to ON and the MODE switch (S2) is set to AUTO. The remote motor-operated disconnect device (M1) is closed. The MicroTurbine and protected loads are connected to the utility. The MicroTurbine is either in the Standby state, or operating in the Grid Connect mode. 2. A utility outage begins. The UVR in the DMSC senses the utility outage, and then opens the normally open UVR contacts and closes the normally closed UVR contacts. 3. The LINE POWER lamp (LP2) extinguishes. 4. Relay RL1 de-energizes. This closes the normally closed contacts of RL1, which is one of the conditions required for Stand Alone operation. 5. Relay RL9 energizes, which energizes relay RL3 and sets the latch of LRL1. The normally open contacts of RL3 close and energize the shunt trip of the remote disconnect device (M1). 6. The remote disconnect device (M1) moves into the tripped position. This isolates the MicroTurbine and protected loads from the utility. Auxiliary contacts M1-A1 close and auxiliary contacts M1-A2 open. The motor operator remains de-energized due to the normally open UVR contacts – therefore the remote isolation device cannot close. 7. The LOAD POWER lamp (LP1) extinguishes. 410071 Rev.
