The invention provides an active protection system of an electromagnetic valve, which comprises the electromagnetic valve, a spacecraft control module and a ground control module. The ground control module is used for setting the preset overtime threshold value and sending a test starting instruction to the spacecraft control module; judging whether the electromagnetic valve is in an open state or not according to a test state signal sent by the spacecraft control module, and if so, starting to calculate the timeout duration; whether the timeout duration exceeds a preset timeout threshold value or not is judged, if yes, a timeout quit test instruction is sent to the spacecraft control module, and the test is ended; the spacecraft control module is used for sending a test instruction to the electromagnetic valve; sending the test state signal to the ground control module; the test state signal comprises the on/off state of the electromagnetic valve; and when the normal test is finished, an exit instruction is
