  2. Zero power factor curve - Wikipedia

    en.wikipedia.org/wiki/Zero_power_factor_curve

    The zero power factor curve (also zero power factor characteristic, ZPF, ZPFC) of a synchronous generator is a plot of the output voltage as a function of the excitation current or field using a zero power factor (purely inductive) load that corresponds to rated voltage at rated current (1 p.u.).

  3. Diesel generator - Wikipedia

    en.wikipedia.org/wiki/Diesel_generator

    A specific model of a generator operated as a standby generator may only need to operate for a few hours per year, but the same model operated as a prime power generator must operate continuously. When running, the standby generator may be operated with a specified - e.g. 10% overload that can be tolerated for the expected short running time.

  4. Droop speed control - Wikipedia

    en.wikipedia.org/wiki/Droop_speed_control

    Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid.

  5. Voltage source - Wikipedia

    en.wikipedia.org/wiki/Voltage_source

    No real voltage source is ideal; all have a non-zero effective internal resistance, and none can supply unlimited current. However, the internal resistance of a real voltage source is effectively modeled in linear circuit analysis by combining a non-zero resistance in series with an ideal voltage source (a Thévenin equivalent circuit).

  6. Shaft voltage - Wikipedia

    en.wikipedia.org/wiki/Shaft_voltage

    Shaft voltage occurs in electric motors and generators due to leakage, induction, or capacitive coupling with the windings of the motor. It can occur in motors powered by variable-frequency drives, as often used in heating, ventilation, air conditioning and refrigeration systems.

    Yanmar also started supplying engines to John Deere tractors [9] and for some Thermo King Corporation coolers used in refrigerated trucks and trailers. [10] Within the last 20 years, Yanmar has also established a growing presence in the domestic unmanned aerial vehicle (UAV) market in Japan and elsewhere, with small helicopter UAVs primarily ...

  9. Voltage droop - Wikipedia

    en.wikipedia.org/wiki/Voltage_droop

    Conversely, when the output current is (near) zero, the voltage at the load is higher. This follows from Ohm's law. Rather than increasing output voltage at high current to try to maintain the same load voltage, droop instead simply allows this drop to take place and designs around it.
