Abstract:
PURPOSE: A power supply stabilization apparatus of a precision processing machine using a micro SMES is provided to supply stably power a sensible and important load by compensating power loss due to flicker, voltage sag, and voltage swell and supplying stably the power. CONSTITUTION: A power supply stabilization apparatus of a precision processing machine using a micro SMES is characterized in that power is stably supplied to a sensible and important load. A micro SMES is used for compensating power loss due to power interruption.
Abstract:
PURPOSE: Provided are a tracer for property of solar battery capable of maximizing stability and utility of solar energy by providing more correct information about solar battery to a user. CONSTITUTION: The tracer for analyzing the property of solar battery by extracting open voltage, short current, optimal voltage, and optimal current from output of the solar battery panel, comprises a solar battery panel(10) for collecting sunlight and outputting voltage and current values; a thermometer for measuring a surface temperature of the panel; a solar radiation meter(20) for measuring an intensity of radiation radiated to the panel; an amplifier(30) for amplifying fine output voltage and output current values resulting from the panel, thermometer, and solar radiation meter into predetermined level of analog value; an analog/digital converter(A/D converter) for converting the analog value(signal) to digital signal; a DC load(40), in which current load varies from 0 to ∞, so as to extract open voltage and short current of solar battery; and a computer(50) for controlling the DC load and processing the digital signal passed through the A/D converter.
