Abstract

PURPOSE: To speed up fault restoration by locating a fault position occurring on a power transmission line in a three-terminal power transmission system according to voltage quantities and current quantities of respective phases after a fault detected at respective terminals of the power transmission line.
CONSTITUTION: Terminal devices A1, B1, and C1 are provided at an A terminal, a B terminal, and a C terminal, voltage quantities and current quantities measured here are sent as data to a center device D, and used to perform vector arithmetic by a prescribed location arithmetic expression, thereby locating a fault point position. Namely, voltages and currents at the respective terminals are sampled and gathered on one place to find voltage drops per unit length of the power transmission system between each terminal and a branch according to the current data from the respective terminals, thereby deciding the section where the fault point is present by using those voltage drops, respective voltage data, and the distances between the terminals and the branch. Then the distance from the terminal in the fault section to the fault point is calculated from the integral value of the voltage drop per unit from the terminal of the fault section and fault section distance.
