Basic tasks of relay protection

The basic tasks of power system relay protection are:

(1) Automatically, quickly and selectively remove the faulty component from the power system, so that the faulty component is protected from continued damage, and other fault-free parts are quickly restored to normal operation.

(2) Responding to the abnormal operating state of the electrical components, and acting on the signal according to the conditions of operation and maintenance (if there are any regular duty personnel), so that the attendant can handle it in time, or the device can automatically adjust, or those that continue to operate Electrical equipment that causes damage or develops into an accident is removed. At this time, it is generally not required to protect the rapid action, but a certain delay according to the degree of damage to the power system and its components, so as to avoid the misoperation caused by unnecessary movements and disturbances caused by the short-running fluctuations.

(3) The relay protection device can also cooperate with other automation devices in the power system. When conditions permit, take predetermined measures to shorten the power failure time and restore power as soon as possible, thereby improving the reliability of the power system operation.
