Title:
電力管理装置、電流センサの設置方向の判定方法及び電力管理システム
Document Type and Number:
Japanese Patent JP6572178
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To appropriately control the time in which determination is made to whether a current sensor installation direction is correct or not and whether determination is possible or not.SOLUTION: A power management device (10) comprises an acquisition unit (13) and a control unit (15). The acquisition unit (13) acquires a current value from a current sensor (30) installed on a power line (U phase) that connects a power system (100) and a load apparatus, and also acquires the voltage value of the power line. The control unit (15) calculates a power value based on the current value and voltage value, calculates an integrated power value of the power values, and determines the installation direction of the current sensor (30) using the integrated power value and determines whether or not it is possible to determine the installation direction of the current sensor (30). The control unit (15) further changes a measurement time or measurement frequencies on the basis of the current value or power value, and determines the installation direction of the current sensor (30).SELECTED DRAWING: Figure 1
