Abstract

The invention discloses a transformer substation relay protection inspection method and system, and belongs to the technical field of power station inspection. The method comprises the steps of obtaining an SCD file of a transformer substation, and analyzing the SCD file to obtain an IP address list of interval layer devices in all stations; according to the IP address list, establishing mms communication services with the interval layer devices in all the stations in sequence; calling protection constant value information of the interval layer devices in all the stations through the mms communication services; and comparing the called protection constant value information with protection constant value information input by a user to obtain a relay protection constant value inspection result. Based on the analysis of the core file, namely, the SCD file of the transformer substation, relay protection constant value checking is realized, the checking efficiency of relay protection equipment constant values is improved, the quality of inspection is greatly improved, and meanwhile three-dimensional missing detection and false detection caused by human factors are avoided, so that safeand stable operation of a power grid can be ensured.

Description

technical field [0001] The invention relates to the technical field of power station inspection, in particular to a substation relay protection inspection method and system. Background technique [0002] At present, the inspection of substations is mainly done manually. During the inspection process, the inspection personnel mainly rely on the self-consciousness of each protection device in the substation, especially during the "peak summer" period or during the power guarantee period. The inspectors complete the inspection of all protective devices in a short period of time, especially the verification of the value of the protective devices and the comparison of sampling information, which takes up a lot of manpower and material resources. Moreover, this manual verification method is too much affected by subjective factors, so the accuracy of the verification cannot be guaranteed. [0003] On the one hand, with the rapid development of the power grid, the scale of the powe...
