PRELIMINARY Grid Connect (Menu 5 of 7) Grid Connect Menu 5 of 7 This menu establishes operating parameters for the Grid Connect mode and are applicable only when the MicroTurbine is operating in the Grid Connect mode. Operating limits, sometimes referred to as Protective Relay Settings, are established here. Submenu 1 of 8 Set Demand Set Demand (Kilowatts) Displays and allows entry of commanded power output level in kilowatts. A password is not required to adjust this parameter from the display panel. The range of valid settings extends from 0 to 2,000,000 kW in 0.1 kW increments. Do not enter a decimal point. To enter 60 kW, simply enter: six zero zero. Default = 0. Submenu 2 of 8 Under Voltage Under Voltage (Volts root mean square) (Delay/Time from 1 to 10 seconds in 0.01 increments) Under Voltage: If the voltage on any phase falls below this setting the timer is started. If the voltage has not recovered at the end of the time period, the system will shut down. This is adjustable from 0 up to the Over Voltage set point (3/8). Default = 360. Under Voltage Delay: Establishes the time period allowed for any phase voltage to fall below the Under Voltage limit established in Vrms. Adjustable from 0.01 up to 10 seconds in 0.01 second increments. The Default = 10. Submenu 3 of 8 Over Voltage Over Voltage (Volts root mean square) (Delay/Time from 1 to 10 seconds in 0.01 increments) Over Voltage: If the voltage on any phase rises above this setting, the timer is tripped. If the voltage has not subsided by the end of the time period, then the system will shut down. This is adjustable from 528 down to the Under Voltage set point (2/8) in 0.1 volt increments. Default = 528. Over Voltage Delay: Establishes time period allowed for any phase voltage to rise above the Over Voltage limit established in . Adjustable from 0.01 to 10 seconds in 0.01 second increments. Default = 10. Submenu 4 of 8 Fast Under Volts Fast Under Volts (Volts root mean square) Fast Under Volts: The system will cease power export to the grid within 1 msec if any phase voltage drops below Fast Under Voltage for 10 msec. If the grid voltage re-stabilizes within 1 second of the initial under voltage, then the system will resume power export, otherwise the system will shut down. The Fast Under Voltage at which this sequence will be triggered is adjustable here from 0 VAC up to the Under Voltage (established in Under Voltage, 2/8). Default = 0. Submenu 5 of 8 Fast Over Volts Fast Over Volts (Volts root mean square) Fast Over Volts: The system will cease power export to the grid within 1 msec if any phase voltage exceeds Fast Over Volts for 10 msec. If the grid voltage re- stabilizes within 1 second of the initial under voltage, then the system will resume power export, otherwise the system will shut down. The Fast Over Voltage at which this sequence will be triggered is adjustable here from the Over Voltage (established in Over Voltage, 3/8) up to 634 volts. Default = 634. Submenu 6 of 8 Under Frequency Under Frequency (Hertz) (Delay/Time from 1 to 10 seconds in 0.01 increments) Under Frequency: If the grid frequency falls below this value for the time period established in Under Freq Delay, the system will shut down. Adjustable from 45 to Over Frequency (established in Over Frequency 7/8), in 0.1 Hz increments. Default = 45. Under Frequency Delay: The number of seconds allowed for Under Frequency condition before the system shuts down. Adjustable from 0.01 to 10 in 0.01 second increments. Default = 10.
