【摘要】：近年來,電網技術向大容量、超高壓、直流輸電的方向快速發(fā)展,500kV電網成為我國電網主架構。而變電站實現(xiàn)無人值班(或少人值守)是提高電網現(xiàn)代化控制和管理水平的一種先進方式,是現(xiàn)代化電網運行管理追求的目標,是電網調度自動化深入發(fā)展的必然趨勢。變電站綜合自動化系統(tǒng)具有信息收集處理量大、信息反饋快等人力不能超越的優(yōu)點,開展500kV變電站無人值班方案的研究,對提高電網的運作效率,提升電網的管理水平,實施集約經營有著積極的意義。隨著中山電力系統(tǒng)規(guī)模不斷擴大,500kV變電站的運行維護成本不斷提高,尤其是對裝置維護性的試驗、定檢而對一次設備的停電,這將增加電力有序供應的難度。。本文針對目前中山500kV電網建設和運行管理狀況,對500kV變電站無人值班綜合自動化系統(tǒng)設計與實現(xiàn)進行了研究。本文首先總結了當前中山電網500kV變電站的運行管理狀況,在此基礎上,對中山500kV變電站實施無人值班綜合自動化系統(tǒng)的可行性和必要性進行了分析,并對500kV變電站無人值班綜合自動化系統(tǒng)進行了規(guī)劃。然后提出了500kV變電站無人值班綜合自動化系統(tǒng)的總體方案,并以桂山站為例,詳細介紹了500kV變電站無人值班綜合自動化系統(tǒng)的軟、硬件設計和改造施工方案。最后給出了中山500kV變電站無人值班綜合自動化系統(tǒng)與傳統(tǒng)有人值班變電站及其他無人值班變電站的對比,證明了所設計的500kV變電站無人值班綜合自動化系統(tǒng)的可行性和效益。
[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.
