POWER SUPPLY MONITORING DATA PROCESSING DEVICE, POWER SUPPLY MONITORING DATA PROCESSING METHOD, AND POWER SUPPLY MONITORING DATA PROCESSING PROGRAM

摘要

A data acquisition unit acquires, as monitoring data for a power supply system provided with a switching unit for selectively outputting AC power supplied from a system power supply or an internal combustion power generation device, an AC/DC converter for converting AC power outputted from the switching unit to DC power and outputting the DC power, and a power storage device connected to a DC bus, first data including the output voltage and/or the output current outputted from the switching unit, and second data including the output voltage and/or the output current outputted from the power supply system. The data processing unit estimates the operation state of the internal combustion power generation device on the basis of the first data and the second data, and generates a modification plan for the discharge lower limit value and/or the system configuration of the power storage device for reducing the operation time of the internal combustion power generation device.
