Secondary intelligent auxiliary design platform for intelligent substation

Abstract

The invention discloses a secondary intelligent auxiliary design platform for an intelligent substation. The platform comprises a data receiving module, an SCD analyzing module, an automatic graphing module, a graph element library, a display module and a safety measure intelligent early-warning module. According to the invention, an operation and maintenance personnel realizes undifferentiated operation and maintenance of the relay protection equipment of the intelligent substation and a conventional substation as on a conventional station working interface; the technical requirements for the operation and maintenance personnel is greatly reduced; the substation safety is improved; the platform provides a complete technical support system for relay protection operation and maintenance of the intelligent substation; the problems of the intelligent substation operation and maintenance are solved as a whole; the ability and efficiency of the operation and maintenance personnel to accurately study, judge and handle secondary equipment defects and power grid faults are significantly improved; during technical innovation, the management innovation of the operation and maintenance of secondary equipment is realized; the fundamental transformation of the operation and maintenance of the secondary equipment of the substation is realized; a powerful technical support is provided for the safe operation of relay protection; and popularization and application prospects are wide.

Description

technical field [0001] The invention relates to an intelligent substation monitoring technology, more specifically, it relates to a secondary intelligent auxiliary design platform of an intelligent substation. Background technique [0002] With the widespread operation of smart substations, the popularization and application of unattended substations and remote operations, how to ensure the safe and reliable operation of smart substations is an urgent problem that needs to be solved. Due to the fundamental changes in the secondary circuit of smart substations, the problems and difficulties in the original secondary equipment control methods and operation and maintenance have gradually emerged, which has increased the risks of on-site operations and power grid operations. The secondary circuit connection, protection outlet, and functional pressure plate of conventional substations can be seen and touched, and can form obvious physical fractures.

Problems solved by technology

Due to the fundamental changes in the secondary circuit of the smart substation, the problems and difficulties in the original secondary equipment control methods and operation and maintenance have gradually emerged, increasing the risk of on-site operations and power grid operation

The secondary circuit connection, protection outlet, and functional pressure plate of conventional substations can be seen and touched, and can form obvious physical fractures. Debugging, operation and maintenance personnel have formed inherent habits. In smart substations, conventional stations can be "visible" , The "tangible" secondary circuit has become an "invisible" and "intangible" "black box", which greatly increases the uncontrollability of substation operation and maintenance, and lacks control over intelligent secondary equipment, SCD files, Effective management and control technical means and technical support platforms such as soft pressure plate and virtual circuit, so intelligent substation relay protection misoperation, miswiring, and misconfiguration frequently occur, and at the same time, when there are defects in protection equipment and its circuits, it is impossible to quickly locate and diagnose, etc. A series of problems seriously threaten the safe operation of smart substations

Therefore, the State Grid Office Bulletin [2015] No. 7 (Shu Yinbiao chaired the new generation of smart substation work report meeting) also pointed out that in the process of substation intelligent development and technological progress, there are still some secondary equipment with insufficient stability and insufficient detection and debugging methods. , Weak front-line operation management in some areas and on-site operation and maintenance personnel not adapting to the development of new technologies, etc.
