摘要： A monitoring device includes a receiving unit receiving effective power output value and reactive power output value from inverter devices, a setting unit setting effective power target value and reactive power output value for each inverter device, a first calculation unit calculating voltage phase command value for each inverter device, a second calculation unit calculating a voltage amplitude command value for each inverter device, a transmitting unit transmitting the voltage phase command value and voltage amplitude command value to relevant inverter devices, a distribution rate calculating unit calculating a distribution rate for each inverter device, and a total value calculating unit calculating effective power total value and reactive power total value for the inverter devices. The setting unit calculates effective power targe value using effective power total value and distribution rate for each inverter device, and also calculates reactive power targe value using reactive power total value and distribution rate for each inverter device.
