A storage unit stores a defect correlation table indicating what influence a given type of defect will have on the inspection of the other types of defects. When an obtainment unit obtains an inspection result of inspecting for a defect, an influence determination unit refers to the defect correlation table and determines the influence of the other types of defects on the inspection result. Information pertaining to the determined influence is outputted via an output unit.

Inspection support apparatus and control method thereof, inspection system, and control program

A power control apparatus includes: a first conversion apparatus that applies DC/DC conversion to direct current power from a power generator for generating power using natural energy, and outputs the resultant power; a second conversion apparatus that applies DC/DC conversion to the power output from the first conversion apparatus and charges a power storage unit with the resultant power, and also applies DC/DC conversion to power from the power storage unit and discharges the resultant power; a third conversion apparatus that supplies alternating current power to a power system and an alternating current load by applying DC/AC conversion to the power output from the first conversion apparatus and/or the power discharged by the second conversion apparatus; and a controller that causes the second conversion apparatus to perform the discharge so that the power output from the third conversion apparatus is higher than power consumed by the alternating current load.

Power control apparatus, power control method, program, and energy management system

A power control apparatus includes: a direct current bus serving as a path for supplying direct current power; a first conversion apparatus that applies DC/DC conversion to direct current power from a power generator for generating power using natural energy, and outputs the resultant direct current power to the direct current bus; a second conversion apparatus that applies DC/DC conversion to the direct current power and charges a power storage unit with the resultant direct current power, and also applies DC/DC conversion to direct current power from the power storage unit and discharges the resultant direct current power to the direct current bus; a third conversion apparatus that applies DC/AC conversion to the direct current power from the direct current bus and supplies alternating current power to a power system and an alternating current load; and a controller that controls driving of the first to third conversion apparatuses.

A diagnosis device () for a solar power generation system, which diagnosis device () diagnoses a whole or a part of an output in the solar power generation system includes: a measurement data acquiring section () for acquiring an electric current value and a voltage value from an ammeter () and a voltmeter (), respectively; and an diagnosing section () diagnoses the output on the basis of a motion of a power point indicated by the electric current value and the voltage value thus acquired.

Evaluation method for solar power generation system, evaluation device, and evaluation program

An output converter includes a DCDC conversion section, a secondary side voltage/current monitoring section detecting a power from the DCDC conversion section, a maximum operation point control section determining what voltage is to be set by the DCDC conversion section so that the power detected by the secondary side voltage/current monitoring section is maximum, a DCDC short-circuit switch via which a current from a module bypasses the DCDC conversion section to outside, a primary side voltage/current monitoring section measuring the current from the module, a module short-circuit switch switching between a state where a secondary side cathode and a secondary side anode are short-circuited and a state where they are not short-circuited, the maximum operation point control section causing the DCDC short-circuit switch and the module short-circuit switch to switch.

Voltage setting device, photovoltaic power generation system, and control method of voltage setting device

An estimated value or a predicted value of an output of photovoltaic generation is easily and properly determined. A learning processor constructs an output calculating model based on a measured value of an output of photovoltaic generation, sunshine hours, and a solar altitude in a learning period. The output calculating model calculates the output of the photovoltaic generation based on the sunshine hours and the solar altitude. An output calculator calculates an estimated value of the output of the photovoltaic generation in an estimation period and a predicted value of the output of the photovoltaic generation in a prediction period based on a measured value of the sunshine hours in the estimation period and the solar altitude or a predicted value of the sunshine hours in the prediction period and the solar altitude. Additionally, the features may be applied to a photovoltaic power system.
