Secondary device online monitoring and analyzing device

Abstract

The invention discloses a secondary device online monitoring and analyzing device which comprises a control board, a power supply board, an interface board, an integrated processing board and an output board. The control board is connected with the power supply board, the interface board, the integrated processing board and the output board. The power supply board is connected with the power supply board, the interface board, the integrated processing board and the output board. The interface board is connected with the power supply board, the integrated processing board and the output board.According to the invention, the secondary device online monitoring and analyzing device is connected with the main station of a provincial dispatching center through a power data communication network(or a dedicated line); network informationization and automatic intelligence of relay protection operation and management and power grid fault handling are realized; information support and decision-making advices are provided for a dispatcher to safely, accurately and quickly deal with power grid accidents; and the device is convenient for a relay protection worker to use.

Description

technical field [0001] The invention relates to an intelligent substation, in particular to an online monitoring and analysis device for secondary equipment. Background technique [0002] At present, power system substations mainly obtain the status information of power equipment through manual inspection, offline experiment, live detection, etc., evaluate the equipment status according to the test plan, judge whether the status of the equipment is abnormal, and predict the failure of the equipment, which is further accurate. Monitoring and understanding the status of equipment creates a huge constraint. [0003] The stable and reliable operation of power secondary equipment is the basic condition for ensuring power safety and maintaining the stability of the power system, and ensuring its stability and reliability is crucial to the entire power system. Whether it is from the perspective of reducing maintenance costs, saving resource costs, or ensuring reliable operation of...
