Yunlong County Immigrants Supporting Projects 35kv Substation Background Of The Old State System Design And Realization

Substation automation system is an important part of modern power substation, and its the economic operation is closely related with the level of technology, safety and reliability, and operation maintenance capabilities. Substation automation system has been widely applied in China power system since the mid-90s of 20th century, although the technology level is not very high. With the rapid development of modern power grid, substation automation system becomes more and more important to the security and stability of the power grid.The main functions of substation automation system consist of data acquisition, operation control, security monitoring, event logging and fault recording function, fault location measuring, data processing and logging, human-computer interaction function, in order to achieve real-time monitoring and control for the substation.Jiuzhou 35kV Substation automation system is designed according to the requirements for standard substation, DEP-4000 series of substation automation system which provided by Shanghai Sunrise Power Technologies Co., Ltd. Is applied in Jiuzhou Substation, and the human-machine interface system is development on Super 2000 software system. 10M/100M Ethernet is used in this automation system. Communication speed, stability of the equipment well met the requirements of designed standard after the system being put into use.
