Abstract

The invention discloses an on-line monitoring outdoor acquisition device for relay protection of a power system in the technical field of power systems. The acquisition device comprises an acquisition conversion module, an information processing module, a communication module, a storage module, a quick interface module, a power supply module and a system clock. The acquisition device realizes local acquisition of information, and provides judgment basis for protective acquisition loop monitoring by modeling according to IEC61850, converting the information into digital signals, transmitting the digital signals through fibers and forming a closed loop circuit between the acquisition device and the primary protective acquisition device.

Description

technical field [0001] The invention relates to a test device in the technical field of electric power systems, in particular to an outdoor collector for online monitoring of electric power system relay protection. Background technique [0002] According to the requirements of DL / T995-2006 "Relay Protection and Power Grid Safety Automatic Device Inspection Regulations", regular inspections are carried out on relay protection, safety automatic devices and secondary circuit wiring to ensure that the device components are in good condition and function normally, and that the circuit wiring and the value is correct. The information to be tested includes the self-test information of the relay protection device, such as device abnormality, power failure, TA / TV disconnection, etc., as well as a large number of components and logical circuit node status information. The current periodic transmission test cannot be reliable and comprehensive. obtain this information. [0003] After...
