The present application provides a multiple protection system for a power system. The multiple protection system particularly comprises a first protection device, a second protection device, a third protection device, a fourth protection device, and an outlet logic circuit, wherein the outlet logic circuit comprises a first logic circuit, a second logic circuit, and a control signal output circuit. The system can output the result of the total protection action if the four sets of protection devices do not withdraw. When one set of protection device exits, any two of the remaining three sets of protection devices can output the total result of protection action. In the case of two sets of protection devices withdrawing, either one of the remaining two sets of protection devices can outputthe total result of protection action; In the case of three sets of protection device withdrawal, the remaining one set of protection device action to output the overall protection action results, sothe system can minimize the risk of protection refusal, while facilitating maintenance, improve the reliability of the overall protection.
