SCD based protection-maintenance-security strategy automatic generation system and method

Abstract

The invention relates to an SCD based protection-maintenance-security strategy automatic generation system and method. The system includes a human-computer interaction module completing human-computerinteraction, a model analysis module which generates a static virtual loop module associated with a maintenance task and obtains a soft pressure plate object corresponding to the maintenance task, astrategy deduction module which generates a rule example according to security rules and performs matching of the rule example with the soft pressure plate object to determine a soft pressure plate operation order, a security ticket generation module which matches a security ticket template with the soft pressure plate operation order to generate a security ticket, and a checking and monitoring module which obtains actual state change information of a security operation isolation point according to the static virtual loop module associated with the maintenance task, compares the actual state change information with content of the security ticket and gives alarm prompt if the actual state change information and the content of the security ticket are not consistent. Compared with the prior art, the SCD based protection-maintenance-security strategy automatic generation system and method can automatically generate the security ticket and perform an abnormity alarm to improve the operationsafety of a substation.

Description

technical field [0001] The invention relates to a system and method for generating protection and maintenance safety measures, in particular to a system and method for automatically generating protection and maintenance safety measures based on SCD. Background technique [0002] The intelligent substation automation system is based on the IEC61850 system. The SCD system configuration tool is used to describe the secondary system of the intelligent substation, and the optical cable is used instead of the cable. The secondary system becomes a "black box". Therefore, how to take safety isolation measures to ensure the safety of the protection system during the maintenance test of the protection device in the smart substation becomes more difficult, and it also increases the operation risk of the smart substation. Contents of the invention [0003] The purpose of the present invention is to provide a system and method for automatically generating protection and maintenance saf...
