Abstract

The invention discloses an intelligent transformer substation relay protection inspection system. The system comprises a server connected to an intelligent transformer substation station control layer network. The server is used for executing a method comprising the following steps of reading and analyzing a SCD file and acquiring an IP address list of a full station spacing layer device; starting an IEC61850MMS client and successively establishing MMS communication with the spacing layer device in the full station according to the IP address list; traversing and taking a fixed value of the device in the station, remote metering and a log and carrying out determination, wherein the step includes taking a protection fixed value information list and a soft pressure plate remote communication information list and comparing to the information list input by a user; and outputting an inspection result, wherein the step includes whether an output relay protection fixed value and pressure plate information are normal. In the invention, relay protection fixed value checking is realized; checking efficiency of a relay protection equipment fixed value is increased; a problem of low efficiency is solved and inspection quality is greatly increased.

Description

technical field [0001] The invention relates to an intelligent substation relay protection inspection system. Background technique [0002] At present, the inspection work of substations is mainly completed manually. During the inspection process, the inspection personnel mainly rely on the inspection personnel to consciously check each protection device of the substation, especially during the "peak summer" period or during the power maintenance period. Complete the inspection work of all protective devices within a short time, especially the verification of the fixed value of the protective device and the comparison of sampling information. This work takes up a lot of manpower and material resources of the protection professional. It is too large, and with the construction of "three sets and five majors", the rapid development of the power grid, the continuous expansion of the scale, the increase of smart substations, and the doubled increase in the workload of protection ...
