Abstract

PURPOSE: To achieve stable operation of a generator with respect to a power system by changing the control from the defective controlling device to the other controlling device, when an over-excitation limiter in one controlling device is actuated and does not go back to the normal state after the predetermined time is elapsed.
CONSTITUTION: Under the condition a generator is running through a controlling device of a group A, a timer 42A is actuated when an over-excitation limiter (OEL) of the group A is actuated. If an AND element 41A is not returned to the normal state after the predetermined time of the timer 42A, a lock-out relay 43A for the failure of the group A is actuated, and the control is changed to the controlling device of a group B if the group B is normal. When the lock-out relays 43A and 43B of the groups A and B are both actuated, a generator lock-out relay 86E is actuated and the generating plant is tripped.
