Intelligent transformer station secondary system model standard library management system and method

Abstract

The invention provides an intelligent transformer station secondary system model standard library management system and method. The model standard library management system manages secondary equipment ICD (Configuration Description) model files in the whole network and transformer station completion version SCD (Substation Configuration Description) model files based on a centralized platform. The system comprises an ICD model library management subsystem and an SCD model library management subsystem. According to the invention, centralized management and publishing of secondary equipment standard ICD models are achieved; the detection content, the model file designation, the model file digital signature, the model file application mode and the like of the ICD models are unified; problems that the engineering application is not standardized, the model detection and the engineering application are disjointed, the model management and control is in disorder and the like as each manufacturer traditionally performs decentralized management on ICD models are solved; and the secondary equipment model standardization level is improved.

Description

technical field [0001] The invention relates to a method in the field of electric power automation, in particular to an intelligent substation secondary system information model standard library management system and a management method. Background technique [0002] Smart substations widely adopt the IEC61850 communication standard, and realize the interoperability between equipment and equipment, equipment and systems in the station through the IEC61850 standardized model and communication services. The ICD (full name: IED Configuration Description) file is a secondary device capability description file, which describes the logical device, logical node and its data objects of the secondary device, as well as project configuration initialization information. The standardization of ICD model is the premise of realizing equipment interoperability. The SCD (full name: Substation Configuration Description) file is a substation configuration description file, which describes the...

AI Technical Summary

Problems solved by technology

In the actual implementation process of smart substation projects, manufacturers often modify the model and configuration by themselves. Every time the model is changed, the on-site commissioning of the smart substation needs to be repeated.

It can be seen that the standardization of secondary equipment information models is not ideal. The same equipment in different regions often uses different models, and the phenomenon of individualization and privatization of models is more prominent, which not only affects the level of equipment interoperability, but also restricts the standardization of smart substations. , which also brings potential risks to the later operation and maintenance, reconstruction and expansion of substations

[0004] In the process of smart grid construction in my country, the construction of smart substations in various regions has a low degree of standardization of the secondary equipment ICD model, the inability to effectively connect the qualified equipment model with the engineering application model, and non-standard configuration and management of the substation SCD model, resulting in the failure of smart substations. The on-site commissioning workload is heavy, the standardized design and commissioning work cannot be carried out effectively, the project construction period is long, and the subsequent operation and maintenance, reconstruction and expansion of substations are difficult, etc.
