Systematic control method for repair based on condition of electricity transmission equipment

Abstract

The invention discloses a systematic control method for repair based on condition of electricity transmission equipment, which divides the repair based on condition of an electricity transmission system into two steps, i.e. the collection of the electricity transmission equipment information and the formulation of a strategy for systematic repair based on condition, wherein the collection of the electricity transmission equipment information comprises the collection of the equipment condition information and the collection of the operating information of the electricity transmission system; and the formulation of the strategy for systematic repair based on condition comprises the following steps: firstly, forming a basic database of the repair strategy, solving by adopting the control algorithm of a repair based on condition system, and checking and outputting to obtain an optimum repair arrangement strategy. The method provided by the invention can reduce the blindness in the repair course, avoids the insufficient repair, comprehensively balances the purposes of enhancing the service life of the equipment and improving the reliability of the system in the repair period, arranges the time interval and type of the repair of the electricity transmission equipment from the point of maximum integral benefit of the system, and enhances the economy and reliability of the repair arrangement of the system.

Description

technical field [0001] The invention belongs to the field of electrotechnical technology, relates to equipment state detection and maintenance planning control strategy method, is a part of the realization of the automatic device of the online state detection and maintenance planning system, is suitable for the maintenance arrangement of power transmission equipment in the power system, and is a part of the realization of the function of the current smart grid. Background technique [0002] The maintenance of the transmission system plays an important role in ensuring the reliable operation of the system, and is an important means to maintain the safe and stable operation of the transmission network, protect equipment and extend its service life cycle. Power equipment maintenance has gone through three stages of development: corrective maintenance (CM), preventive maintenance (PM) and predictive maintenance (PdM). [0003] a. Maintenance after accident [0004] Post-acciden...

Problems solved by technology

[0008] ① It is necessary to cut off the power for testing, and many important power equipment cannot be easily out of operation;

[0009] ②The equipment status (such as voltage, temperature, etc.) is inconsistent with the operation status after the power failure, which affects the accuracy of judgment;

[0010] ③Because it is a periodic periodic test, failure may still occur during the 2 tests

[0014] However, since the power transmission system is a complex system composed of multiple devices, there are constraints such as network constraints, power flow constraints, and reliability constraints. The importance of the equipment in the system and the complexity of the system itself are not considered, and only the use of a single device is extended. Starting from the service life
