Smart Substation Secondary Intelligent Aided Design Platform

Abstract

The invention discloses a secondary intelligent auxiliary design platform of an intelligent substation, which includes a data receiving module, an SCD analysis module, an automatic drawing module, a graphic element library, a display module and an intelligent early warning module for safety measures. The invention enables the operation and maintenance personnel to work in the same interface as the conventional substation, realizes the non-differentiated operation and maintenance of the relay protection equipment of the intelligent substation and the conventional substation, greatly reduces the technical requirements for the operation, maintenance and maintenance personnel, and improves the safety of the substation at the same time. The platform provides a complete technical support system for the operation and maintenance of relay protection in smart substations, which solves the problems existing in the operation and maintenance of smart substations as a whole, and significantly improves the ability and efficiency of operation and maintenance personnel to accurately determine and deal with secondary equipment defects and grid faults. While carrying out technological innovation, it has realized the management innovation of the operation and maintenance of secondary equipment, realized the fundamental transformation of the operation and maintenance of secondary equipment in substations, provided strong technical support for the safe operation of relay protection, and has broad prospects for promotion and application.

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.
