PROBLEM TO BE SOLVED: To provide a system and a method for finding an electric power consumption of a load in a power supply section of an ungrounded power distribution system.SOLUTION: A border of a power supply section is defined by an import device which connects the power supply section to an upstream power supply section and at least one export device which connects the power supply section to a downstream power supply section. An electric power consumption of each load is represented as the product of a magnification and basic electric power defined by a load profile of the load. A power flow of the power supply section is solved using the electric power consumption of the load, and active power of each phase of the import device is generated. Target active power of each phase of the import device is found using a measurement value of the import device, and the magnification is updated based upon the difference between the active power and target active power. |
