IEC 61850 is an international standard for digital substation automation systems based on network communication platform. It has been widely used in power generation, transmission, distribution and scheduling. The protocol implemented unified modeling for object, enhanced interoperability and interchangeability between different terminals. In this paper, we apply the protocol is to power and environment...
Large scale application of intermittent energy resources in distribution network has brought about great challenges to information processing on operation-management level. To make the processing more scientific and orderly, the concept of hierarchical and distributed control mode was put forward, in which all the DER systems in one distribution network are divided into several self-control areas,...
In recent years, photovoltaic (PV) power generation is developing rapidly on account of its environment friendliness. However, the PV devices between different manufacturers could hardly interoperate because of different model and protocols they applied. This paper built the information model for PV power generation based on IEC61850, which is more normative and convenient for PV plant configuring...
Micro-grid is proven to be an effective way to adopt renewable generation in a disperse manner. For information sharing barriers between different inverter manufactory, which are caused by self-definition interfaces of devices, the method of standardized information modeling is proposed, and communication model of low-voltage micro-grid based on IEC61850 is built in this paper. In the unit layer of...
IEC61850, based on general-purpose network communication platform, is the only international standard in substation automation system, using XML Schema technical definition of the public information model. These models and modeling method is the standard's core. The traditional method is static modeling. By analyzing the lack of static modelling, the dynamic modeling method, its practical value and...
Agent-based wide-area backup protection (WABP) systems have been studied to improve the security of power system in recent years. IEC61850 has become an approved international communication standard for substation automation system. In order to make WABP device conform to the developing of substation automation system, the information model of wide-area backup protection based on IEC61850 is proposed...
The standard way to deploy substation network information system is based on IEC61850 'Communication Networks and Systems in Substations', which is confined to individual substation domain. In order to develop cross-substation applications without affecting the lower level operation mode, the information class model defined in IEC61850 needs to be expanded. Another dilemma is that the object oriented...
