Research On 110kV Substation’ Intelligent Control Technology

The grid technology is constantly developing as the development of social technology.the demand of people for energy is increasing, while the efficiency of the operation and maintenance of traditional substation has been unable to accommodate this demand. so the State Grid Corporation of China put forward the construction of "a strong and unified grid" to meet this demand, and as an integral part of the smart grid,the intelligent substation need for further construction and renovation.This article outlines some of the key technologies which related to intelligent substation, and using the examples of which the Jiangxi province’s new generation of intelligent substation ’s Modification and debugging experience to study and conclude the Operation and maintenance mode of intelligent substation and the specific reform measures of intelligent optimization and some project of inteligent transformation.This article study the specific project of the tranditional substation ’s inteligent transformation. using by transforming Intelligent Unit which was installed on the basis of field survey of electrical equipments to promote the intelligent level of primary equipment.rebuiding the substation’s secondary system to adapt the equipments’ s new for old period and redesign the equipments’ s secondary system running scheme during the transformation;rebuid the inteligent substation’s communications network by using the IEC 61850.according to the Message transmission mode to transfer the primary equipment’s control information,such as breaker and switch blade.intelligent transform make the substation ’s Primary and secondary transformer substation equipment had Procedural operation function;By using the GOOSE Message to control the protection trigger signals,The interaction between the protection’s atresia and the control of the primary equipment.
