摘要: There is provided an inverter (1) to be applied to a solar power generation system (10) interconnecting with a system bus (7). The inverter measures a system voltage (Vr) of the system bus (7), detects a voltage drop of the system bus (7), based on the measured system voltage (Vr), controls a DC voltage (Vdc) by an MPPT (22) when the voltage drop is not detected, and performs control to raise the DC voltage (Vdc) without relying on the MPPT (22) when the voltage drop is detected.

摘要: There is provided an inverter control apparatus (2) which controls an inverter (1) interconnected to an alternating-current power system (9). A capacitor (6) is on an alternating-current side of the inverter (1). The apparatus detects the system voltage (Vr) of the alternating-current power system (9), calculates the differential value of the detected system voltage (Vr), calculates a correction current instruction value (Ic) for correcting a current instruction value (Ir0) set for the output current (Iiv) of the inverter (1), based on the calculated differential value of the system voltage (Vr), corrects the current instruction value (Ir0) based on the calculated correction current instruction value (Ic), and controls the inverter (1), based on the corrected current instruction value (Ir1).

摘要: A control apparatus (2) for an inverter (1) detects an output voltage deficiency of the inverter (1) based on a system voltage (Vr) of an AC power system (7) and a DC voltage (Vdc) applied to the inverter (1), detects distortion of an output current (Iiv) based on a harmonic included in the output current (Iiv), performs maximum power point tracking control on the inverter (1), and controls to set the DC voltage (Vdc) applied to the inverter (1) to a voltage at a power point less than a maximum power point (Pmpp) of the maximum power point tracking control when the output voltage deficiency (Viv) is detected and the distortion of the output current (Iiv) is detected.
