摘要： A method for fault location is provided which can accurately perform a fault location process by a simple and direct calculation without requiring no synchronization of terminals. Data relating to the voltage and the current (vector quantity) at opposite ends of a power transmission line section to be located and a transmission line constant set in advance are used. When the distance x from a designated terminal A to a fault point F is an unknown quantity, the distance x can be calculated by solving a quadratic equation obtained by taking as the fault point a point where values of the second power of a fault point voltage in a fault phase when viewed from opposite ends of the section to be located are equal to each other.

摘要： According to an embodiment, a fault point location method of locating a fault point by using a voltage and a current of each terminal of a transmission line to be located and a transmission line constant is disclosed. According to the method, a formula simplified by a secondary approximation using an approximation of a hyperbolic function from a basic equation of a distributed constant circuit equation using the hyperbolic function or a formula simplified by a division of both sides by the hyperbolic function is determined. A location distance from a predetermined end of the transmission line to the fault point is calculated by using the simplified formula.
