摘要： Photovoltaic (PV) array emulators and methods are described. In one example, a method for use in testing a PV inverter includes coupling a first PV inverter to an alternating current (AC) power source. A second PV inverter is coupled to receive an output of the first PV inverter. The first PV inverter is operated to emulate a PV array and provide a DC power output to the second PV inverter.

摘要： A device includes a controller that receives current values generated by at least four parallel load commutated inverters (LCIs). The controller includes a source firing generator that generates independent source firing commands for each of the at least four parallel LCIs based on the received current values and transmits each of the independent source firing commands to a respective one of the at least four parallel LCIs, wherein the source firing commands are configured to set input phase angle values of the four parallel LCIs.

摘要： A control system for controlling a multiphase power converter includes a current control module, a voltage control module and a current command selector. The current control module generates grid voltage command signals for the multiphase power converter and the voltage control module generates reference converter current command signals for the current control module. The current command selector supplies active and reactive current command signals from a supervisory controller to the current control module when the multiphase power converter is connected to the grid and supplies the reference converter current command signals to the current control module when the multiphase power converter is unconnected to the grid.
