Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 , figure 2 As shown, this embodiment provides a method and system for intelligent substation network simulation combining virtual and real. In this embodiment, a PC is used to analyze the substation project configuration file (SCD), analyze the data structure and model, establish a virtual network communication node, and connect with the real equipment or subsystem of the substation to form a closed-loop network, and simulate the flow of the virtual network communication node through the PC terminal. Throughput, simulated storms, etc., to verify the performance of the closed-loop network. The invention can be applied to simulate and check the communication network of the substation after reconstruction and expansion before the new generation of intelligent substation is reconstructed or expanded, or can be applied to network f...

Abstract

The invention relates to a virtual-real-combined intelligent substation network simulation method and system. A substation project configuration document is analyzed through a PC, data structure and models are analyzed, virtual network communication nodes are established, and docking with substation real equipment or subsystem is realized to form a closed-loop network; and through the PC, flow, throughput and simulation storms and the like of the virtual network communication nodes are simulated, so that the performance of the closed-loop network is checked. The method and system can be used for carrying out simulation verification on the substation communication network obtained after reconstruction and expansion in advance, or used for checking network fault of each subsystem of the substation before reconstruction and expansion of a new generation of intelligent substation.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a method and system for intelligent substation network simulation combining virtual and real. Background technique [0002] With the promotion and construction of a new generation of smart substations, the level of intelligence in substations continues to increase. Among them, the communication network is the bridge between various subsystems and equipment in the substation, and its performance greatly affects the safety and reliability of the power system. At present, there are few application technologies for communication network simulation in substations, especially in the process of reconstruction and expansion of the new generation of substations, there is a lack of a communication network simulation technology combining virtual and real, which can combine the existing real communication network with the pre-retrofit and expansion virtual communication nodes ...
