Abstract

The invention discloses an on-line monitoring and analysis device for secondary equipment, comprising a control board, a power board, an interface board, a comprehensive processing board, and an output board; the control board is respectively connected to the power board, the interface board, the comprehensive processing board, and the output board ; The power board is connected to the power board, the interface board, the integrated processing board, and the output board respectively; the interface board is connected to the power board, the integrated processing board, and the output board respectively. The secondary equipment online monitoring and analysis device of the present invention is connected to the main station of the network and the provincial dispatching center through the power data communication network (or dedicated line). It realizes the network informatization and automatic intelligence of relay protection operation, management and grid fault handling, and provides information support and decision-making staff for dispatchers to safely, accurately and quickly handle grid accidents; it is convenient for relay protection personnel 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...
