Capstone Turbine Corporation • 21211 Nordhoff Street • Chatsworth • CA 91311 • USA Technical Reference: Dual Mode System Controller (DMSC) When the SA Enable and Start/Stop inputs become active, the microturbine enters the transition state and will begin exporting power in Stand Alone mode within the transition time (seven seconds + the setting of the Fast Transfer Delay, which has a default value of 0 and can be set through either CRMS or display panel). Note that if a valid control input is not received before the microturbine completes its Hot Standby timeout, the microturbine will shut down and remain in normal Standby until valid control inputs tell it to restart in Grid Connect or Stand Alone mode. GC Enable SA Enable Active Inactive Stop Active Start < 50ms Inactive < 7s Start/Stop MicroTurbine Output MicroTurbine State Grid Connect Hot Standby Transition to Stand Alone Stand Alone Figure 23. Grid Connect to Stand Alone with Intentional Delay The above scenarios explain how an external system can use inputs to the microturbine to force transition from Grid Connect to Stand Alone operation with or without intentional delay. However, the microturbine itself includes built-in protective relay functions that may operate before any external control system has responded. This is, in fact, the more probable scenario, and is Capstone’s recommended operating scheme. By letting the microturbine respond directly to a utility fault, the protected loads may actually have more continuity of power if they are not automatically transferred to Stand Alone mode. Figure 24 shows operation of the microturbine from Grid Connect to Stand Alone, where the microturbine initiates the transfer. For simplicity of explanation, the example shows a drop in utility voltage as the fault. Of course, it could be other fault conditions that cause this operation, such as over or under frequency, over voltage, or anti-islanding protection. 410071 Rev D (January 2010) Page 57 of 71 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.PDF Image | Dual Mode System Controller DMSC
