Embodiment Construction

[0032] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] An embodiment of an intelligent substation IED interchange method of the present invention:

[0034] During the design period of the smart substation, a one-time design is carried out according to the final scale of the smart substation. The interval of pre-expansion is replaced by the ICD of the typical device model to form the SCD file of the whole station; The signal and physical port name of the terminal, and establish a virtual terminal mapping library.

[0035] Such as figure 1 As shown, when constructing the virtual terminal mapping library, protection devices for different device types and application types define the virtual terminal mapping relationship of different manufacturers in XML format. The mapping library describes the type and application scope of the protection device, as well as the IED name, model, and virtual...

Abstract

The invention relates to an intelligent substation IED interchange method and device. The method is characterized by constructing a virtual terminal mapping database by collecting ICD models of products passing state grid company relay protection and safety automatic device professional test; and when an intelligent substation is reconstructed and expanded, and a secondary system of the intelligent substation is configured, virtual terminal connection lines can be replaced quickly according to the virtual terminal mapping database. The intelligent substation IED interchange method and device reduce workload of on-site engineers and improve configuration accuracy; the virtual terminal mapping database can be used repeatedly; and when a new product is released, the virtual terminal mapping database is updated synchronously, thereby facilitating operation personnel to carry out corresponding processing and improving operation and maintenance efficiency of an intelligent device.

Description

technical field [0001] The invention belongs to the technical field of intelligent substation secondary system configuration, and in particular relates to an intelligent substation IED (intelligent electronic device) interchange method and device. Background technique [0002] The information communication standard of the smart grid substation information flow platform is IEC61850. IEC61850 provides the definition and construction method of the data model of each IED information resource in the substation automation system, and provides the communication service system of the data model. The goal of IEC61850 is to realize the interoperability between IEDs in substations and the interchangeability of IEDs in substations. Interoperability refers to the exchange and sharing of data information between IEDs in the substation, which is realized by configuring the data models on each IED in the substation. Currently, the mutual configuration of data models is usually performed man...
