Method and device for checking correctness of virtual terminal association configuration in smart substation

Abstract

The invention relates to a checking method and device for correctness of virtual terminator association configuration of an intelligent substation. The method comprises the steps that primary equipment and the topological relation of the intelligent substation are obtained according to an SSD file of the intelligent substation; the secondary function configuration, corresponding to the primary equipment, of secondary equipment is obtained according to the SSD file; the logic connection relation between secondary functions of the secondary equipment of the intelligent substation is obtained according to the primary equipment, the topological relation and the secondary function configuration corresponding to the primary equipment; correctness of virtual terminator two-end IED / LD / LN association configuration in the logic connection relation is checked according to a preset rule. Secondary virtual circuit logic connection errors caused by virtual association configuration errors can be rapidly and effectively checked, maloperation caused by the virtual terminator association configuration errors is avoided, risk of misoperation of running equipment is reduced in the reorganization, expansion and debugging process of the intelligent substation, and safe production and reliable operation of the intelligent substation are ensured.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a method for checking the correctness of the associated configuration of virtual terminals in an intelligent substation, and a device for checking the correctness of the associated configuration of virtual terminals in an intelligent substation. Background technique [0002] Smart substation adopts advanced, reliable, integrated and environment-friendly intelligent equipment, with the basic requirements of digitalization of whole station information, networking of communication platform, and standardization of information sharing, and automatically completes basic functions such as information collection, measurement, control, protection, measurement and detection. At the same time, it is a substation with advanced functions such as real-time automatic control of the power grid, intelligent adjustment, online analysis and decision-making, and collaborative interact...

Problems solved by technology

Smart substation virtual terminal associated configuration errors are not errors such as syntax configuration, which cannot be checked by conventional tools, and for smart substation virtual circuit logical connection configuration, for example, the trip circuit of a protection device for a certain circuit breaker should be connected to the smart terminal device of the circuit breaker The correctness check of the function logic of the secondary virtual circuit such as the tripping input circuit, there is currently no plan involving

[0004] At present, the association configuration of virtual terminals in smart substations is basically realized manually, and there is a lack of methods for checking the correctness of the logical configuration of the secondary virtual circuit, so the correctness of the logical configuration of the secondary virtual circuit cannot be guaranteed.

And for the reconstruction and expansion commissioning of smart substations, if the security measures are not in place, the associated configuration error of the virtual terminal may also cause the risk of misoperation of the running equipment, and bring safety hazards to the reconstruction and expansion commissioning of smart substations
