Online state maintenance intelligent decision analysis device used for relay protection device, and signal processing method and application thereof

Abstract

The invention discloses an online state maintenance intelligent decision analysis device used for a relay protection device, and a signal processing method and an application thereof, and belongs to the field of application of the information technology of power systems. The online state maintenance intelligent decision analysis device used for the relay protection device comprises a data acquisition unit, a data adapter, a storage unit, a state evaluation unit, a warming detection unit, a maintenance decision-making unit, a guide unit, a guide configuration interface unit, a controlling unit, a universal algorithm module, an arithmetic configuration interface unit and a WEB page presentation unit. After the attribute information of the quantity of state of the relay protection device is collected in real time, the maintenance decision analysis and the warning detection to various protection devices in the power network can be realized through the universal state evaluation algorithm model in the independent module.

Description

technical field [0001] The invention belongs to the application field of power system information technology, and more specifically relates to an intelligent analysis device for on-line condition maintenance of relay protection equipment with different voltage levels in the power industry, a signal processing method and its application. Background technique [0002] With the development of the scale of the power grid and the continuous increase in the number of equipment, the requirements for technical level and reliability are rapidly increasing, and the traditional mode of regular equipment maintenance has been difficult to adapt to the new management requirements. The State Grid is in the process of gradually transforming from the scheduled maintenance mode (TBM) to the condition-based maintenance mode (CBM). Relay protection devices need to realize on-line condition maintenance, using the self-inspection, measurement, fault recording and communication functions of microc...
