FAULT DETECTION AND DIRECTION DETERMINATION |
摘要 |
Methods and apparatus are provided for fault detection and direction determination with a phase overcurrent relay using individual phase torques and the negative sequence torque, and with a ground overcurrent relay using the zero sequence torque. A directional element includes a ground element logic circuit, a negative element logic circuit and a phase element logic circuit to evaluate the operation state of the system, detect a fault condition and determine the direction of the fault condition in an electrical power distribution system having multiple sources on a power grid. |
