Embodiment 1

[0013] In order to meet the requirements of on-line monitoring of electric power automation system, in this embodiment, the sensor monitoring logic node in IEC61850 standard is extended, so that the application can be extended to lightning location, icing point on-line monitoring and power quality on-line monitoring, etc.

[0014] An IEC61850 model extension method includes the following steps: extending logical nodes, adding lightning location monitoring SLLC, ice-covered point monitoring SIAC, and power quality monitoring SPQC to sensor monitoring logical nodes after standardizing and defining them respectively. Described below:

[0015] 1. Lightning location supervision

[0016] The process of standardizing and defining the lightning location monitoring SLLC may specifically include: defining common logical node information, measurement values, and status information in the lightning location monitoring SLLC logical node; wherein:

[0017] The public logical node informati...

Embodiment 2

[0043]In fact, in order to better apply the IEC61850 model to the electric power automation system, we can also make more extensions to the IEC61850. Because the IEC61850 model is mainly used to realize the communication between IED devices, the definition description of some models is too simple and does not meet the requirements of the public information model in the power automation system, so it is absolutely necessary to make more extensions to IEC61850.

[0044] As a better example, such as figure 1 As shown, an IEC61850 model extension method may include the following steps:

[0045] Step S1, perform general extension specification. When applying the IEC61850 model to the power automation system, all primary equipment must be clearly defined to join the CIM (Common Information Model, public information model) model using URI (Uniform Resource Identifier, universal resource identifier), and in the SCL specification The primary device does not have a definition of URI, ...

Abstract

The invention provides an IEC (International Electrotechnical Commission) 61850 model extension method, which comprises the following steps of: extending logical nodes, and respectively regulating and defining and then adding lightning location supervision SLLC (Series Lighting Location Compensator), ice accretion supervision SIAC (Series Ice Accretion Compensator) and power quality supervision SPQC (Series Power Quality Compensator) to sensor monitoring logic nodes. According to the IEC61850 model extension method, an IEC61850 model is extended, the common online supervision such as the lightning location supervision SLLC, the ice accretion supervision SIAC and the power quality supervision SPQC are added to the sensor monitoring logic nodes, so that the logic nodes required by device state monitoring are increased, and thus the application range of the IEC61850 in system modeling is broadened, and the flexibility of the IEC61850 in system modeling is improved simultaneously.

Description

technical field [0001] The invention relates to the technical field of substation system modeling, in particular to an IEC61850 model extension method. Background technique [0002] With the continuous advancement of computer technology, communication technology and power electronics technology, the demand for information sharing and application integration in power systems is becoming more and more urgent. To this end, the 57th Technical Committee (IEC TC57) of the IEC (International Electro technical Commission, International Electrotechnical Commission) has formulated a series of standards, including the IEC 61970 standard for the EMS (Energy Management System) of the dispatch center and the SAS for the substation (Substation Automation System) IEC 61850 standard. Trying to establish a standard and open power system information model to promote interoperability between applications, reduce production and maintenance costs, and improve system reliability. [0003] Among ...
