Problems solved by technology

However, in the existing grid equipment state mode evaluation method, when monitoring the equipment state, if one of the equipment states changes, all equipment must be re-evaluated, and the efficiency of this processing method is too low.
In addition, the status of the existing equipment is mainly evaluated by the staff. There are many manual interventions and different standards. It is easy to cause omissions and the quality is difficult to control.

Abstract

The invention relates to the field of electric power system analysis and control, and particularly discloses an automatic evaluation platform and an automatic evaluation method for power grid equipment status. The automatic evaluation method includes: extracting monitoring data in real time on line; retrieving data which changes; finding out an equipment classification which power grid equipment which changes belongs to according to the data which changes; invoking an evaluation model for evaluating; and grading evaluation results, and proposing an overhaul proposal. The automatic evaluation platform and the automatic evaluation method for the power grid equipment status can comprehensively diagnose equipment insulation status according to various testing information and equipment operation status, provides decision support for fault locating and equipment overhauls, and can efficiently and accurately evaluate the power grid equipment status in real time.

Description

technical field [0001] The invention relates to the field of power system analysis and control, in particular to an automatic evaluation platform and method for power grid equipment status. Background technique [0002] Condition-based maintenance (CBM) first originated in the United States. After the 1990s, it began to be practically applied in the power production of countries such as the United States, Germany, the United Kingdom, and Japan. It includes predictive maintenance (PDM) and condition-based maintenance (RCM) with reliability as its core. At present, Europe and the United States mainly adopt the RCM mode. The main point of this implementation mode is not only to grasp the real situation of the equipment through status detection, but also to consider the importance of the equipment in the system and the impact of the failure of the equipment on the reliability of the power grid. , to formulate the final maintenance plan. In other words, the importance weight of...
