Management method of functions of multi-agent-based digital substation

Abstract

The invention provides a management method of functions of a multi-agent-based digital substation. The management method organically combines the multi-agent technology, the IEC 61850 standards and the functions of the digital substation. The basic idea of the management method is to standardize the functions of the digital substation, the multi-agent technology is adopted to carry out the management of the independent functions and the logic nodes involved by the functions are distributed to the different agents according to the specific demands of the different substations; adopt the autonomy in the agents, and the agents carry out the communication through a protocol stipulated by the IEC 61850 standards; and SCL (substation configuration language) is adopted to carry out the configuration and the management of the agents. The method has the advantages that the method adopts the consistent concept and means during the whole process from the analysis, the design and the implantation of a substation automation system to the maintenance, solves the unified management problem of the distributed functions of the IEC 61850 standards and is also applicable to other links of a power system, thereby being capable of establishing an unified information and communication platform of the whole system.

Description

technical field [0001] The invention belongs to the field of power system automation, in particular to multi-agent (Multi-Agent) technology, IEC61850 substation communication network and system standards, and digital substation technology, and provides a multi-agent-based digital substation function management method. Background technique [0002] Digital substation and related technologies are hot issues in the field of power system automation in recent years. It is the result of the development of computer technology, network technology, and power system requirements. IEC 61850 standard, multifunctional IED (Intelligent Electronic Device) and communication network are the key research contents. [0003] The IEC 61850 standard was formulated by the TC57 working group of the International Electrotechnical Commission on the basis of summarizing the previous communication protocols, in order to realize seamless communication between devices from different manufacturers. Its c...

Problems solved by technology

[0005] At present, the research and application of the integrated IED of measurement, control and protection based on the IEC 61850 standard and the digital substation are mainly based on the original equipment or system, and the transformation and practice of the communication protocol and model mapping for the IEC 61850 standard. The organization and management of functions are still carried out in the original way, and functions at different levels cannot be effectively organized and utilized, such as from logical nodes to IEDs, and it is difficult to give full play to the advantages of free distribution of functions and coordinated operation
