Abstract
Official abstract text for this publication.
Provided is a power converter capable of reducing cross current. The power converter 1 includes a phase controller 20 that calculate a phase angle reference value θm based on a difference between a commanded active power reference value Pe and an output active power P supplied to a distribution line 5, a voltage controller 10 that calculates a voltage reference values Vu, Vv, and Vw based on the phase angle reference value θm calculated by the phase controller 20, and a power conversion unit 52 that converts, based on the voltage reference values Vu, Vv, and Vw calculated by the voltage controller 10, an electric power supplied from a power supply source 60 into AC power and outputs it to the distribution line 5.
First claim
Opening claim text (preview).
The invention claimed is: 1. A power converter, comprising: a phase controller calculating a phase angle reference value based on a difference between a commanded active power reference value and an output active power supplied to a distribution line, a voltage controller calculating a voltage reference value based on the phase angle reference value calculated by the phase controller, and, a power conversion unit converting, based on the voltage reference value calculated by the voltage controller, an electric power supplied from a power supply source into AC power and outputs it to the distribution line, wherein the phase controller adds a control amount for proportional control based on a difference between the active power reference value and the output active power and a control amount by a first-order lag controller based on the difference between the active power reference value and the output active power to calculate the phase angle reference value. 2. A power converter, comprising: a phase controller calculating a phase angle reference value based on a difference between a commanded active power reference value and an output active power supplied to a distribution line, a voltage controller calculating a voltage reference value based on the phase angle reference value calculated by the phase controller, and, a power conversion unit converting, based on the voltage reference value calculated by the voltage controller, an electric power supplied from a power supply source into AC power and outputs it to the distribution line, wherein the phase controller adds a control amount for proportional control based on a difference between a phase angle difference reference value and a measured phase angle difference and a control amount by a first-order lag controller based on the difference between the active power reference value and the output active power to calculate the phase angle reference value. 3. The power converter according to claim 2 , wherein: the phase angle difference reference value is calculated based on the active power reference value, a reactance to the distribution line, and the output voltage effective value. 4. A power converter, comprising: a phase controller calculating a phase angle reference value based on a difference between a commanded active power reference value and an output active power supplied to a distribution line, a voltage controller calculating a voltage reference value based on the phase angle reference value calculated by the phase controller, and, a power conversion unit converting, based on the voltage reference value calculated by the voltage controller, an electric power supplied from a power supply source into AC power and outputs it to the distribution line, wherein the phase controller calculates the phase angle reference value based on a control amount for proportional control based on a difference between a phase angle difference reference value and a measured phase angle difference.
