Abstract

See full text

A power conversion apparatus includes an inverter circuit, a system voltage measurement unit measuring a system voltage, a voltage drop detector detecting a voltage drop of a power system, based on the system voltage, a direct current power measurement unit measuring a direct current power to be input into the inverter circuit, an alternating current command value calculator calculating an alternating current command value to control an alternating current output from the inverter circuit, based on the direct current power and the system voltage, and a current limiter that decrease a current limit value to limit the alternating current command value, when the voltage drop is detected.
