The invention relates to a method for switching double intelligent terminal device remote communication quantity in an intelligent substation, and belongs to the technical field of automation of electric power system substations. The method includes the steps: firstly, setting an optional hard opening-inserting in intelligent terminal device opening-inserting plug-ins into an opening-inserting power monitoring opening-inserting; enabling shaking elimination time of the opening-inserting power monitoring opening-inserting to be shorter than that of the rest hard opening-inserting within a standard range; switching double intelligent terminal devices according to received opening-inserting power monitoring states, keeping all states of GOOSE (generic object oriented substation event) remote communication quantity of last change before the opening-inserting power monitoring states are zero when the received state of opening-inserting power monitoring remote communication quantity of any intelligent terminal device is zero, automatically switching to one intelligent terminal device, and switching the double intelligent terminal devices. The remote communication quantity of the intelligent terminal device in the opening-inserting power monitoring state is 1. The double intelligent terminal device remote communication quantity is intelligently switched when network communication reliability and intelligent terminal running stability are ensured.
