摘要： A method and system are provided. The method includes synchronously reconnecting a microgrid to a main grid after islanding of the microgrid. The synchronously reconnecting step includes calculating a phase angle difference between synchrophasor measurements collected from a common coupling on the main grid and synchrophasor measurements collected from a common coupling on the microgrid. The synchronously reconnecting step further includes calculating, by a controller, a frequency reference deviation based on the phase angle difference. The synchronously reconnecting step also includes adjusting a frequency of the diesel generator based on the frequency reference deviation.

摘要： A cooling system including a thermosyphon subsystem and a spray cooling subsystem, each being configured to evaporatively cool a component, and a controller configured to selectively operate the spray cooling subsystem based on the cooling requirements of the component. The controller controls a valve limiting the operation of the thermosyphon when the spray cooling system is active. The component is configured to run in a plurality of performance states including a low power state and a high power state. The spray cooling system operates when the component is in the high power state. The controller can order the component to operate in a lower power state if the cooling systems are inadequate to the cooling needs. The cooling needs are determined with a component temperature sensor, a vapor temperature sensor, a vapor pressure sensor, or a power usage sensor.
