The invention relates to an SV straight mining and GOOSE shared-port protection device testing method. A hand-held terminal is added between a comprehensive intelligence unit and a protection device and connected with the comprehensive intelligence unit and the protection device through an optical port respectively, an SV message sent from the comprehensive intelligence unit is shielded when an integral group test is performed, an SV message is regenerated according to preset fault data, the SV message and a GOOSE message are combined, packaged and forwarded to the protection device, a GOOSE tripping message sent from the protection device is forwarded to the comprehensive intelligence unit after being received, a circuit breaker is tripped, and accordingly a scene integral group transmission test is achieved. According to the SV straight mining and GOOSE shared-port protection device testing method, the problem that a fault quantity value needs to be applied to the transformer side or the configuration of the protection and comprehensive intelligence unit needs to be modified to achieve the integral group test through a tester under the way of the new generation of intelligent transformer substation SV/GOOSE shared-port is solved.
