Abstract: An alternating current (AC) line emulator includes an AC power supply and an automatic regulating load. The AC power supply is used for providing an AC line frequency and an AC line voltage. The automatic regulating load is coupled between the AC power supply and a grid-connected power generation system for functioning as a test load of the grid-connected power generation system, and preventing current from reversing to the AC power supply and shutting down the AC power supply. When the grid-connected power system is tested, power consumption of the automatic regulating load is equal to a sum of output power of the grid-connected power generation system and output power of the AC power supply.

The DC voltage/AC voltage inverter converts the DC voltage and outputs an AC voltage to an AC power supply network. The DC link capacitor adjusts power outputted by the DC voltage/AC voltage converter to regulate the DC voltage.

Abstract: A method and a system for detecting stand-alone operation of a distributed generating system having a generating source connected in shunt with an independent power distribution system via a first branch breaker are proposed. A voltage or a frequency signal on the independent power distribution system is read. The wavelet transformation is performed on the voltage or frequency signal to form a time versus high-frequency component window and a time versus low-frequency component window for conveniently detecting the perturbation in the time domain of the signal. Next, whether the absolute value of the high-frequency component is greater than a threshold value and whether the duration is longer than another threshold value are determined. If both answers are yes, a stand-alone operation occurs. An alarm signal is immediately generated and sent to the first branch breaker to release the connection between the generating source and the power distribution system.
