Summary:PURPOSE: A current flow calculation system for a power distribution line is provided to find out an optimal solution within shortest time by use of a nonlinear planning method. CONSTITUTION: A current flow calculation system includes an input means, a setting means for calculation conditions, and a calculation means. The input means receives data like load states, detection state of generator capacities, connection state concerning transmission lines and electric machines, and tap ratios of transformers. The setting means for calculation conditions generates objective functions for minimizing the generation costs with the input data and facility data stored in a database. It also formulates various conditions concerning the power system to an augmented Lagrange function. The calculation means solves the augmented Lagrange function with an augmented Lagrange multiplier method. 본 발명은 비선형 계획법에 의한 최적조류계산 시스템에 관한 것으로, 전력계통에 있어서 가장 경제적인 발전기의 출력분포와 단자전압, 조상 설비량 및 변압기 탭등을 결정하는 최적 조류계산 시스템에 관한 것이다.
