The invention provides one-to-many intelligent substation process layer virtual secondary equipment and an implementation method. The implementation method comprises the steps of establishing different file directories and downloading an ICD model configuration file, reading a parameter configuration file, analyzing the ICD model configuration file inside a device to obtain a message structure and parameters, setting a one-to-many message transmission method in a remote manner and sending a message. The implementation method provided by the invention can effectively realize decoupling of a hardware architecture and an information model, achieves parallel analog simulation and serial analog simulation of multiple sets of different equipment by means of one set of hardware equipment, can effectively satisfy the debugging requirements for analog simulation with multiple different intervals of intelligent substation reconstruction and expansion projects, further effectively constructs an simulation debugging environment of the intelligent substation reconstruction and expansion projects, provides an effective solution for field debugging of the intelligent substation reconstruction and expansion projects, and enhances automated debugging level and debugging efficiency.
