Abstract: PURPOSE: A method for detecting a single operation based on a correlation using current disturbance is provided to improve power quality by using a correlation index for numerically calculating the correlation of an inverter current and an inverter power. CONSTITUTION: The root mean square values of a system voltage, an inverter output voltage, and an inverter output current are calculated(S100). The zero point of the root mean square value of the inverter output voltage is set(S110). The disturbance of the inverter output current is set(S120). A correlation index is calculated by analyzing the correlation of the inverter output voltage and the inverter output current(S130). The correlation index is compared with a boundary value(S140). If the correlation index is the boundary value or more, it is determined that a single operation is detected and an inverter stops(S150).
