Abstract

The invention discloses a relay protection testing and simulation control device. The relay protection testing and simulation control device comprises a relay protection control module, a simulation control module, a switching switch, a power amplifying module, a switching value input and output module and a power module. The relay protection control module is connected with a first data port; a simulation control module is connected with a second data port; the switching switch comprises two groups of switch paths; the power amplifying module and the switching value input and output module are connected with the relay protection control module through one switch path of the switching switch and connected with the simulation control module through the other switch path of the switching path. The relay protection testing and simulation control device integrates the functions of relay protection testing and simulation control, thereby meeting the functional requirements of a single relay protection object on testing operation as well as meeting and optimizing the functional requirements on distributed relay protection simulative testing, optimizing the system configuration of simulative testing of a distributed relay protecting system and improving the utilization rate of testing equipment of an intelligent transformer substation.

Description

technical field [0001] The invention relates to the technical field of power system testing, in particular to a relay protection testing and simulation control device. Background technique [0002] The smart substation is a new type of substation to support the development strategy of the large power grid and realize the goal of coordinated intelligent control of the large regional power grid. It is technically a great improvement over traditional substations. Due to the above-mentioned technical changes in smart substations, a new situation of decentralized arrangement of equipment and information digitization has been brought about: according to the design requirements, the smart substation installs the bay layer protection unit in the protection room, and the process layer sampling unit and control unit are located in the local primary Next to the equipment, the two are connected through optical fiber; the information transmission mode of analog and switch values ​​obtai...
