An effective, yet relatively simple and inexpensive, method for detection of islanding in distributed power generation systems. Statistical analysis of the local line frequency, as measured at the distributed generator, is performed to detect when an island has been formed. The statistical characteristics of the local frequency are controlled by the grid when the distributed generator is not islanding. When an island is formed, however, frequency control switches to circuitry associated with the distributed generator. Because the statistical characteristics of the frequency control performed by the distributed generator are markedly different from those of the grid, the islanding condition can be detected and corrected. 1. A method of detecting island formation in a distributed power system including at least one distributed generator interruptably coupled to a grid through a feeder , the method comprising:using a frequency measurement device to compile a plurality of values of frequency change in the power system, measured over a predetermined time window;using a processor to group the plurality of values of frequency change into a plurality of bins, at least a first one of the bins representing an expected behavior of power frequency change when the feeder is grid-tied, and at least a second one of the bins representing an expected behavior of power frequency change when the feeder is islanded;using the processor to apply a predetermined decision criterion to the grouped values to determine whether the feeder is islanded or grid-tied; andautomatically decoupling the distributed generator from the feeder if the feeder is determined to be islanded.2.

The method of claim 1 , further comprising:determining whether the transport refrigeration system includes a network coordinator backup power source; andinstructing the one or more parasitic electronic devices of the transport refrigeration mode to operate in the hibernation mode when the input voltage of the transport refrigeration system power source remains below the voltage threshold value for the time period, the control unit is off, and the transport refrigeration system does not include the network coordinator backup power source.3. The method of claim 1 , further comprising:detecting whether the transport refrigeration system includes a network coordinator backup power source; andswitching the network coordinator to receive power from the network ...

Subsea Electrical System Having Subsea Penetrator with Integral Current Sensor

Номер: US20130286548A1
Автор: Pierrick Andrea, Serge Bernard Yves Arrive
Принадлежит: Schneider Electric Industries SAS

A system and method for coupling electrical power subsea. The system comprises a subsea penetrator to seal an opening around a conductor extending through a partition or enclosure. The subsea penetrator comprises an integral current sensor operable to produce a signal representative of current through the conductor. The penetrator comprises a boot configured to seal the opening through which the conductor extends. The current sensor may be disposed within the boot.
