| Integrated substation automation technology is the trend of the development of the power in the future, with the deepening of the power grid renovation, all integrated automation transformation substation shall be complete, realization of substation integrated automation, and the implementation of the unattended, reduce the pressure of a shortage of staff, make the enterprise economic benefit is improved.The company was upgraded to 110kV substation integrated automation system of Dong Guan tun in 2012, In this paper, the design principle, computer monitoring system design technology, relay protection and automatic device design technology of the integrated automation system are described in detail.Based on the structure of integrated automation system in 110kV substation to Dong Guan Tun, According to design requirements, This paper mainly description the following aspects of the work. First description the development of the integrated automation system of the substation. The design principle and structure of integrated substation automation system are described. And then by comparing the structure of several integrated automation system. To determine the structure design of the substation integrated automation system in the design of the substation integrated automation system. The technology of relay protection system of relay protection system is compared. Finally, the selection of data acquisition system is introduced in detail.The actual operation shows that, the comprehensive automation of the 110kV substation to Dong Guan Tun design scheme is consistent with the actual situation, achieved the expected goal. The proposed substation computer monitoring system and microcomputer protection system technology is very advanced technology program, will play the important role of the development in Dong Guan Tun. |
