Smart substation is one of the key parts of smart grid and the network of process layer is an important foundation for smart substation which is related to the reliability and real-time of data acquisition and switch control. The type of message of process layer which include GOOSE (General Object-Oriented Substation Event), MSV (Multiple Sample Value) and synchronization with network are generalized. The scheme of process layer network with different combination of the GOOSE and MSV are discussed. The unite scheme of GOOSE, MSV and synchronization with IEEE1588 is researched, the scheme of hybrid mode which fits the requirements of relay protection of smart substation is presented in detailed. The VLAN and GMRP technology which is used to divide the network of process layer to reduce the load of network is proposed, it will be useful to the construction of smart substation.
