Publication number: 20110184673Abstract: 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.Type: ApplicationFiled: July 9, 2009Publication date: July 28, 2011Applicant: Kabushiki Kaisha ToshibaInventors: Hideyuki Takani, Hideaki Sugiura, Mika Ohashi
