Numerical control testing device for electrical power system field intelligent stability control device

Abstract

The invention discloses a numerical control testing device for an electrical power system field intelligent stability control device. The numerical control testing device comprises a configuration control unit and a host processing unit, wherein the configuration control unit is connected with the host processing unit through the Ethernet. The host processing unit comprises a host CPU processing module which is connected with an Ethernet interface module, a GPS timing module, an optical interface converting module, an electrical interface module and an input converting module. The Ethernet interface module is externally connected with an Ethernet interface. The optical interface converting module is externally connected with twelve optical interfaces. The electrical interface module is externally connected with two electrical interfaces. The input converting module is externally connected with ten input interfaces, and the input interfaces are in abutting connection with the stability control device to be tested. In addition, a power source module is arranged to supply power to the modules. By the adoption of the numerical control testing device for the electrical power system field intelligent stability control device, the requirements for electrical quantity, input and multi-state coordinated changes of each interval needed by testing the intelligent stability control device are met; a channel testing function is added for channels of a plurality of stability control devices between a plurality of stations, and the channels between the stability control devices, the distance function of the stability control devices and the channel function can be conveniently tested.

Description

technical field [0001] The invention relates to a device for debugging the function and channel verification of an intelligent stability control device based on the IEC61850 standard in a power system, and in particular to a digital inspection device for a pan-domain intelligent stability control device of a power system. Background technique [0002] At present, intelligent substations have been gradually promoted. Power systems including intelligent substations must be equipped with stability control devices. Whether the functions and channels of the stability control devices meet the requirements requires another set of special stability control device testers. tested. [0003] When testing the intelligent protection tester of the existing power system stability control device, the focus is on whether the technical requirements of the protection function of the stability control device can meet the corresponding standards—that is, it fully considers the various types of f...

Problems solved by technology

However, the stability control device can be divided into an independent stability control device and a system composed of multi-station connection. The intelligent protection tester for the existing power system stability control device only considers the test of the independent stability control device. The correlation and coordination between the stability control devices composed of multiple stations are not considered, and the inspection requirements for the correlation of the stability control devices with multi-interval and multi-component input cannot be fully met; at the same time, for the stability control devices composed of multiple stations, more It is necessary to verify the communication channel between the stability control devices

However, as far as the current situation is concerned, in the field of power system stability control devices, there is still no test platform developed for the particularity of intelligent stability control and a test platform for remote communication protocols.
