Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0027] like figure 1 Shown is the network structure diagram of the present invention. The substation end includes intelligent substation monitoring system, measurement and control device, protection device, fault recording device and other parts. As an advanced application module of the intelligent substation monitoring system, the intelligent alarm and fault analysis module is responsible for analyzing the measurement and control device, protection device, and fault recording device. All kinds of information sent up, combined with topology technology and automatic identification of each type of fault in the fault reasoning model, generate a fault analysis report and send it to the dispatching ...

Abstract

The invention relates to an intelligent warning and fault analysis realizing method applied to an intelligent transformer substation monitoring system, which belongs to the technical field of transformer substation automation. An intelligent warning and fault analyzing module is used for analyzing various pieces of information reported by a measurement and control device, a protective device and a fault recorder, generating a fault analysis report by combining topology with every fault in an automatic identification fault reasoning model, and submitting the generated fault analysis report to a scheduling master station at a master station end. The workload of personnel on duty is greatly reduced, and the fault processing efficiency is improved. The requirement of an intelligent transformer substation on an intelligent warning and fault analysis system can be met, faults can be quickly judged and analyzed, and processing schemes can be provided so as to assist the personnel on duty in quickly processing the faults, and reduce the loss caused by the faults.

Description

technical field [0001] The invention belongs to the technical field of substation automation, in particular to a method for realizing intelligent alarm and fault analysis of a substation automation system. Background technique [0002] At present, the State Grid Corporation of China is vigorously promoting the construction of smart grids. Various advanced sensing and measurement technologies, communication technologies, computer information technologies, and control technologies are highly integrated with the physical grid. The technical difficulty of running jobs continues to increase, and the efficiency of running jobs needs to be further improved. In the current operation of substations, traditional manual work still occupies a large proportion. With the promotion of digital substations, there are more and more signals in substations. However, operating experience shows that during substation accidents and serious abnormalities, the output Most of the large amounts of i...
