The invention provides an imaging generation method for an input virtual terminal of an intelligent substation SCD (System Configuration Description). The imaging generation method comprises the following steps: firstly, automatically searching an inner virtual terminal of a certain IED (Intelligent Electronic Device); utilizing an imaging technology to display a related virtual terminal, the input virtual terminal and sending source information thereof, and an inner virtual terminal to be related on an interface in a partition and column graphing manner; applying imaging dragging and dropping to appointing the corresponding input virtual terminal to the inner virtual terminal; submitting in two phases to officially form the input virtual terminal. The imaging generation method has the beneficial effects that (1) all the inner virtual terminals of the local IED are automatically searched and displayed; (2) all the inner virtual terminals of equipment are displayed in upper and lower regions in a partitioning manner; (3) the sending source information of each input virtual terminal and description thereof and data citing are given in columns and displayed; (4) all sending virtual terminals sent by the certain IED can be found rapidly and accurately to be used as standby input virtual terminals of the local IED; (5) the input virtual terminal is generated or updated through dragging and dropping operation and two times of submitting; the operation process is direct and convenient.
