Abstract
A rotation calculation unit calculates a rotation speed of a virtual generator on the basis of a rotor model to simulate driving of the virtual generator and calculates the rotation speed of the virtual generator. A target power determination unit determines target values of active power and reactive power of an inverter on the basis of the calculated rotation speed. A command generation unit generates a control command for the inverter on the basis of the determined target values of the active power and the reactive power.
Claims5
A command generation device for generating a control command for an inverter configured to convert DC power output from a DC power source device into AC power synchronized with a frequency of a bus, the command generation device comprising:
- a rotation calculation unit configured to calculate a rotation speed of a virtual generator and calculate the rotation speed of the virtual generator on the basis of a rotor model to simulate driving of the virtual generator;
- a target power determination unit configured to determine target values of active power and reactive power of the inverter on the basis of the calculated rotation speed;
- and
- a command generation unit configured to generate a control command for the inverter on the basis of the determined target values of the active power and the reactive power.
A command generation method for generating a control command for an inverter configured to convert DC power output from a DC power source device into AC power synchronized with a frequency of a bus, the command generation method comprising:
- a step of calculating a rotation speed of a virtual generator on the basis of a rotor model to simulate driving of the virtual generator and calculates the rotation speed of the virtual generator;
- a step of determining a target value of active power of the inverter on the basis of the calculated rotation speed;
- and
- a step of generating a control command for the inverter on the basis of the determined target value of the active power.
