[Abstract]:In recent years, the power network technology to the direction of large capacity, ultra-high voltage, direct current transmission rapid development of 500kV power network has become the main structure of the power network in China. The realization of unattended substation is an advanced way to improve the level of modern power network control and management, is the goal of modern power network operation management, and is the inevitable trend of the development of power grid dispatching automation. Substation integrated automation system has the advantages of large amount of information collection and processing, fast information feedback and so on. The research on the unattended scheme of 500kV substation can improve the operation efficiency of power network and improve the management level of power network. The implementation of intensive management has a positive significance. With the expansion of Zhongshan electric power system scale, the operation and maintenance cost of 500kV substation is increasing, especially the maintainability test of the equipment and the blackout of the primary equipment, which will increase the difficulty of the orderly supply of electric power. According to the construction and operation management of Zhongshan 500kV power network, this paper studies the design and realization of the integrated automation system of 500kV substation. This paper first summarizes the current operation and management situation of 500kV substation in Zhongshan Power Grid, and then analyzes the feasibility and necessity of implementing the unmanned integrated automation system in Zhongshan 500kV substation. And the integrated automation system of 500 kV substation without on duty is planned. Then, the overall scheme of the integrated automation system for 500 kV substation is put forward. Taking Guishan station as an example, the hardware and software design of the integrated automation system for 500 kV substation is introduced in detail, as well as the reconstruction construction scheme. In the end, the comparison between the integrated automation system of unmanned duty in Zhongshan 500kV substation and the traditional unattended substation and other unattended substations is given, which proves the feasibility and benefit of the designed integrated automation system for 500kV substation.
