Abstract

The invention relates to the technical field of power grid operation, specifically to an intelligent protection apparatus, and aims to solve the problem of inconvenient operation and control caused by the fact that an intelligent terminal, a combining unit, a protection apparatus and a measurement and control apparatus in the intelligent transformer substation are all independently mounted, so as to realize unified management and control. The intelligent protection apparatus comprises an analog quantity acquisition unit, a protection calculation unit, an action analysis and calculation unit, a configuration parameter setting unit, an operational parameter setting unit, a recording unit and a man-machine interaction unit, wherein the analog quantity acquisition unit is externally connected with an intelligent transformer substation D5000 platform; the analog quantity acquisition unit is in one-way communication with the protection calculation unit, the action analysis and calculation unit and the recording unit separately; the protection calculation unit is in one-way communication with the action analysis and calculation unit and the intelligent transformer substation D5000 platform separately; the action analysis and calculation unit, the protection calculation unit, the configuration parameter setting unit and the operational parameter setting unit are in one-way communication with the recording unit separately; and the recording unit is in one-way communication with the man-machine interaction unit.

Description

technical field [0001] The invention relates to the technical field of intelligent substation operation and maintenance, in particular to an intelligent protection device. Background technique [0002] At present, the intelligent terminal, merging unit, protection device and measurement and control device in the smart substation are installed independently, and query, operation and control are more troublesome. The development of a multifunctional intelligent protection device to realize the unified management and control of intelligent terminals, merging units, protection devices and measurement and control devices in smart substations is of great significance for improving the operation and maintenance management level of smart substations. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent protection device for unified management and control of the intelligent terminal, merging unit, protection dev...
