| Substation automation system is developed on the basis of computer and network communication technology. In recent years, the science and technology develop rapidly, and the replacement and stereotypes of electronic products are faster than before. From the recent application of modern network systems and practices, it has brought a series of technical innovations in the use of substation automation system for substation design, installation, commissioning and operation, maintenance and management.According to the understanding of the Substation automation system, the article combines with some form of application architecture of intelligent substation automation systems at domestic and abroad. Particularly, those based on interval-oriented, object design of hierarchical distributed integrated automation architecture model of integrated automation system in Huai’an intelligent 110kV Yugou exchange, and proposed feasibility of the design scheme and the innovation improvements.Around the Huai’an intelligent 110kV integrated automation system’s design and implementation, this article mainly carried out the following studies:(1) Connected with the Current status substation automation systems and related research, combined with foreign advanced technology to improve the design of the integrated substation automation system.(2) The subject’s test section selects variable hub and the District Town called Yugou town of Huai’an as the experimental segment, firstly, to outline the grid structure Yugou Town, and then analyze Yugou Town grid’s needs upgrading and Yugou substation’s construction target, and outline intelligent the basic characteristics of substation automation system, finally, to analyze the intelligent building 110kV substation hub for the location of Yugou which brings economic and social benefits.(3) Analysis of the Huaian intelligent 110kV Yugou exchanges integrated automation’s design, includes the main design principles of the substation, and the system structure and the main functions of the selection requirements. According to the feasibility study, design principles, system configuration, device configuration, and network protection function proposed 110kV Yugou exchanges intelligent of Huaian,(4) Analysising of the Huaian intelligent 110kV Yugou exchanges integrated automation equipment selection and function realization. Building up the integrated substation automation network system to make sure the various information is reliable. It is necessary to combine the hardware and software to establish the background monitoring systems, and to provide the human-computer interaction and system condition of the modern intelligence substation monitoring system.By terms of the structure, function, application result of the integrated automation system design, and executed from the equipment selection, IED and five anti-system and other aspects of substation integrated automation system. This design of 110kV Yugou exchanges integrated automation system can not only meet the performance substation control precision, fast response, reliable data transmission of the basic requirements, but also has strong augment ability and ease of using and easy to maintain.In the whole process of design and implementation of intelligent substation system, the full account of the status of the grid structure and recent development of Yugou Town. Early to check the variable grid system of Yugou town,and combine the prospective to take the analysis of the status of power grid. The design is based on the basis of the existing substation improvements, to do on the basis of full integration with the existing grid structure, and reserved on the space for the automation upgrading and transformation is about 220kV substation. In addition, to adapt the requirements of the current development trend of the grid, and also gives full consideration after completing the intelligent substation system, how about the capability of distributed energy absorption. |
