POWER DISTRIBUTION NETWORK ESTIMATION DEVICE AND POWER DISTRIBUTION NETWORK ESTIMATION METHOD

摘要

PPROBLEM TO BE SOLVED: To enhance the accuracy of the determination of a system in a power distribution network, the determination of the state of connection of a load between sensors in the system, and the estimation of the power consumption of the system within a predetermined range. PSOLUTION: A power distribution network estimation device and a distribution network estimation method are provided, the device being provided between an electric power-supply end provided for supplying power from a power distribution network to multiple loads and a load connected to the electric power-supply end, and the device and the method are configured to change a resistance value between a power supply terminal of the electric power-supply end and a ground terminal, to communicate with a sensor for measuring a voltage value between the power supply terminal of the electric power-supply end and the ground terminal, and to use the voltage measured by the sensor so as to determine a system in the power distribution network, determine the state of connection of a load between sensors in the system, and estimate the power consumption of the system within a specified range.
