Switching value tripping control method for relay protection device

The invention discloses a switching value tripping control method for a relay protection device. The method comprises the steps of dynamically generating a tripping sequence table which stores ID (Identity) numbers of relays needing to be tripped in a CPU (Central Processing Unit); sequencing the ID numbers of the relays in the tripping sequence table according to the sequence from the high level to the low level; and only showing the ID number of each relay in the tripping sequence table once in one period. According to the switching value tripping control method, a hardware circuit with a simple structure can be matched for use, a series of control methods are provided to adapt to an alternating current power supply and a direct current power supply, the switch value acquisition and switch value fault trip can be maintained simply and stably.
