Support system for evaluating status of electric power equipments, and maintaining strategy

Abstract

An evaluation and support system of electric power device state comprises system management module for managing test process, authority, organization and personnel; data management module for classifying and managing device data such as device type, device parts, device parameter, weight ant test parameter; state evaluation management module for obtaining healthy state result of electric power device by calculating and analyzing means.

Description

Power equipment status assessment and maintenance strategy support system technical field The invention relates to the field of maintenance and repair of power system equipment, in particular to a power equipment state evaluation and maintenance strategy system. Background technique my country's electric power companies have been implementing a unified national periodic maintenance system for a long time, and its essential feature is based solely on time cycles. This model obviously has the following problems: ① Regardless of the actual condition of the equipment. Execute the pre-specified maintenance cycle without exception, excessive maintenance and insufficient maintenance coexist, the result of which is to cause a lot of ineffective investment and financial loss. Insufficient maintenance is the enemy of equipment safety, and it is the root cause of major vicious accidents such as steam turbine overspeed and boiler explosion; ② The pertinence is not strong during t...

① Regardless of the actual condition of the equipment

Execute the pre-specified maintenance cycle without exception, excessive maintenance and insufficient maintenance coexist, the result of which is to cause a lot of ineffective investment and financial loss

Insufficient maintenance is the enemy of equipment safety, and it is the root cause of major vicious accidents such as steam turbine overspeed and boiler explosion;

② The pertinence is not strong during the maintenance process, the equipment status is not well grasped, and the key points cannot be highlighted during the maintenance;

③ The current maintenance cycle does not conform to the failure law of the existing equipment life. A large number of equipment statistics at home and abroad show that: the failure rate curve of any equipment within the life span is a bathtub-shaped curve, and the same cycle is implemented throughout the life of the equipment. Sexual overhaul is unscientific and does not conform to the objective reality of the equipment;

④Negative effects are often produced: at present, it is mainly overhauling, which damages some original good equipment and increases the probability of misoperation, mistouching, and miswiring
