Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] The present invention not only expresses the virtual circuit between the virtual terminals on a drawing, but more importantly, expresses the physical port and access point of the smart device corresponding to each virtual terminal; not only can all the virtual terminals be clearly distinguished on the drawing Corresponding physical ports, describe in detail the physical ports of the device corresponding to each virtual circuit; at the same time, clearly distinguish the access points corresponding to all virtual terminals on the drawing, and describe in detail the access points corresponding to each virtual terminal; in addition, Express the specific name and model of the smart device in the drawing.
[0018] figure 1 The "**line protection" in the "PCD-122-D" model is the expression of the name of the smart device; the primary equipment associat...

The invention discloses a representing method of a corresponding relationship between virtual circuits and physical ports in a secondary circuit graph. Due to the facts that the secondary circuit graph is drawn on the basis of the virtual circuits and the physical ports to represent an interoperation relationship between intelligent devices in an intelligent substation, the representing method of the corresponding relationship between the virtual circuits and the physical ports in the secondary circuit graph has the advantages of representing the virtual circuits between virtual terminals on one piece of graph paper, more importantly, representing a physical port, corresponding to each virtual terminal, of an intelligent device and an access point corresponding to each virtual terminal at the same time, clearly representing a virtual terminal signal transmitted in an optical cable, greatly facilitating debugging and operation management work of a later stage substation, being capable of rapidly finding a fault cause of a physical port when some signal or all signals are out of order, and achieving coupling of the design of a physical layer of the intelligent substation and the design of the logical layer.
Description
technical field [0001] The invention relates to a method for expressing the corresponding relationship between a virtual circuit and a physical port in a secondary circuit diagram. Background technique [0002] Smart substations (including digital substations) use the latest communication technology and information processing technology. Compared with conventional substations, their structure and form have undergone revolutionary changes. In conventional substations, signal transmission is realized through cable connections. Signals and There is a one-to-one correspondence between cables; in smart substations (including digital substations), signals are transmitted between smart devices through the network, and cables or optical cables can only reflect the connection relationship in communication at best, and cannot describe real functional interoperability, mutual relationship. According to the State Grid Corporation's design specifications for smart substations, the d...
