SINGLE-PHASE LINE VOLTAGE CALCULATING METHOD OF A SMART ELECTRICITY DISTRIBUTION OPERATING SYSTEM, AND RECORDING MEDIUM FOR SAME

WIPO Patent Application WO/2012/036339

A1

Provided is a single-phase line voltage calculating method of a smart electricity distribution operating system. The single-phase line voltage calculating method includes: calculating each phase voltage value by using a current value measured from a three-phase bus, and defining a bus reference point of the three-phase bus; obtaining connection information on the three-phase bus and a single-phase branch line, and modeling a branch joint matrix of the single-phase branch line with respect to the bus reference point on the basis of the connection information; establishing a voltage equation of the single-phase line with respect to the bus reference point from the branch joint matrix that is modeled based on each calculated phase voltage value and an impedance of the single-phase branch line; and determining whether a repeating calculation result value of the voltage equation satisfies a convergence condition, and calculating a voltage value for each single-phase branch line on the basis of a determination result.
