“…Load block consists of a transmission line and a load which is the sum of loads in Fig. 3(a) [7]. The transmitting power possible to transmit through a load block is defined as transmission line capacity minus load power in a load block.…”

Restoration guidance system for trunk line system

“…With the increasing demand for the reliability of electric power supply and the expansion of the system scale, it has become indispensable that the system be restored quickly and accurately when a fault occurs in a power system. For this reason, automatization or support of the restoration operation after the fault by a computer has attempted and promoted in recent years [1][2][3][4][5][6]. Thus the stage of practical implementation is being attained in local supply systems [7].…”
