OPERATING MODES CHAPTER 4 OPERATING MODES This section describes the Grid Connect and Stand Alone operating modes including transitions between these operating modes MultiPac operation and Dispatch modes Grid Connect Introduction Grid Connect mode allows the C1000 MicroTurbine package to be connected in parallel with an electric utility When a utility grid disturbance occurs the integrated protective relay functions of the 200 kW MicroTurbine power modules will automatically shut down the system The C1000 package can restart automatically to resume supplying electricity to connected loads once grid power returns to normal In Grid Connect mode the C1000 MicroTurbine generator package is a current source only the MicroTurbine synchronizes to the electric utility for both voltage and frequency reference The MicroTurbine can be used to provide base load power or shave peak power based on loads or user commands Features Grid Connect functionality and user benefits are optimized in the C1000 MicroTurbine package through several advanced features of the C1000 controller Besides optimizing turbine efficiency for a given power output and minimizing emissions the C1000 controller will balance power module run times and offers numerous custom and time of use controls for precise dispatch of power according to the users needs The time of use feature includes programmable peak shaving functions which automatically configu

Modem and MicroTurbine Settings The MicroTurbine port speed setting must be set to the same speed as the modem Some telemetry modems have different modes for data packet transmission For the MicroTurbine to communicate properly the transmitted data packets should never be split For example some modems have a mode for example DOX mode by which the data packets are kept together during transmission The modem used for communication with the MicroTurbine should be TCP IP capable and have Ethernet port connections instead of a serial connection This would allow a single modem to be used to access multiple MicroTurbines at the same site Wireless Modems For remote MicroTurbine installations where no landline telephone service is available a radio or cellular modem is highly recommended for monitoring and troubleshooting the MicroTurbine system Several third party cellular and radio modems have been successfully used with the Capstone MicroTurbines Resources for Wireless Modems A list of recommended modem vendors and model numbers that may be suitable for installation at your location is presented below Contact your local cellular telephone service companies for a list of cell modems with coverage in your area For telemetry and radio modems be aware of local and FCC regulations as well as permits required for using air radio frequencies The usage of some radio frequencies may require special licenses 410072 Rev A January 2009
