Abstract: A phase sequence adjustment system includes a power conversion circuit and a control circuit. The power conversion circuit is connected to a main power supply with a phase sequence. The control circuit respectively provides a first and a second excitation signals to the power conversion circuit, so as to short the power conversion circuit with the main power supply twice. The control circuit includes a current detection circuit and a control unit. The current detection circuit obtains two current signals respectively during two short-circuit operations. The control unit calculates two current phase angles respectively according to these two current signals and determines whether the phase sequence is positive or negative accordingly. The control unit selects one from the two current phase angles, calculates a voltage phase angle of the main power and a phase angle difference there-between to adjust a feedback phase sequence accordingly.

Abstract: A consensus-based power control apparatus is provided, which includes a real power control module and a reactive power control module. A real power consensus signal between a first power generating apparatus and a second power generating apparatus is provided and a frequency restoration signal is generated according to the real power consensus signal, thereby allowing the real power control module to generate a real power output signal. A reactive power consensus signal between the first power generating apparatus and the second power generating apparatus is provided and a voltage differential restoration signal is generated according to the reactive power consensus signal, thereby allowing the reactive power control module to generate a reactive power output signal. Therefore, the invention can control real power and reactive power input signals (i.e., actual real power and reactive power outputs) of the first power generating apparatus in a grid system.
