Capstone Turbine Corporation • 21211 Nordhoff Street • Chatsworth • CA 91311 • USA Application Guide: Dual Mode Fast Transfer Application Guide Summary The C60/C65 Dual Mode version MicroTurbines with firmware version 4.50 and higher are able to transition from Grid Connect to Stand Alone, and from Stand Alone to Grid Connect operation, with only a few seconds of time delay between these operating modes. Capstone calls this capability “Fast Transfer”, which can be extremely beneficial for protected loads that value high availability of power. This application guide explains how Fast Transfer functions, how it works with the Capstone Dual Mode Controller, and provides general application guidance. Refer to other Capstone Product Specifications and Technical References listed at the end of the application guide for more details. In summary, the C60/C65 Dual Mode MicroTurbines in combination with Capstone’s Dual Mode Controller, are able to provide less than 10 seconds transition time between Grid Connect operation and Stand Alone power in the case of a Utility outage, and to reconnect the protected loads back to the Utility grid within 2 seconds after normal conditions have been reestablished. The sections below provide the details on how the C60/C65 MicroTurbine and Dual Mode Controller function to accomplish this high level of load protection. UL 1741 Requirements for Utility Interconnection C60/C65 MicroTurbines are UL listed to 2200 and 1741, and meet the harmonics requirements of IEEE 519. They are also pre-certified for Utility interconnection by many local jurisdictions to simplify connecting to the Utility grid, such as in California and New York. These local certifications often rely on the UL 1741 listing, which defines how power inverters must react to disturbances on the Utility grid. Before describing the Fast Transfer capability of the C60/C65 Dual Mode version MicroTurbines, it may be useful to review how the C60/C65 achieves the UL 1741 listing and how it operates under typical Utility grid disturbances. Figure 1 shows a one-line schematic of a C60/C65 Grid Connect version MicroTurbine connected to the Utility grid. In this example, short circuit and overload protection is provided by the circuit breaker CB1 between the MicroTurbine and the Utility grid. The protective relay functionality required by UL 1741 is integral to the C60/C65 firmware, and includes voltage, frequency, and anti-islanding functions. Following is a short description of how the basic C60/C65 Grid Connect version (not a Dual Mode version) reacts to a Utility disturbance.
