Embodiment Construction

[0015] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 As shown, a new type of digital relay protection test equipment includes transient real-time simulation plug-in, merging unit plug-in, intelligent terminal plug-in, communication fault setting plug-in, I / O plug-in, and chassis. The core of the described transient real-time simulation plug-in is a parallel computing array composed of multiple FPGA chips, which satisfies the requirements of a system real-time simulation, and unidirectionally outputs real-time voltage and current simulation data to the merging unit plug-in through the Ethernet communication interface; The merging unit plug-in described above receives the real-time simulation data from the transient real-time simulation plug-in, which uses a single FPGA chip as the control chip, a...

Abstract

The invention discloses a novel digitization relay protection testing device which comprises a transient state real-time simulation plug-in, a merging unit plug-in, an intelligent terminal plug-in, a communication fault setting plug-in and an I / O plug-in. The transient state real-time simulation plug-in, the merging unit plug-in, the intelligent terminal plug-in and the communication fault setting plug-in are connected through an Ethernet optical fiber communication interface. The testing device and hardware of the testing device share one casing. The device can test digitization relay protection more comprehensively and effectively; on the premise of finishing testing the digitization relay protection, the construction cost of a testing platform is effectively reduced; faults possibly occurring in a communication network of a process level of a digitalized substation are truly simulated, and the reliability and the safety of digitization relay protection in the actual operating process are ensured.

Description

technical field [0001] The invention relates to the technical field of digital substations, in particular to a new type of digital relay protection testing equipment. Background technique [0002] With the promotion and construction of digital substations, new devices such as electronic transformers, merging units, and intelligent switches have been introduced into substations. The emergence and application of these new devices not only improve the flexibility of internal organization and distribution of information in digital substations, but also promote The development of electrical equipment in the direction of compactness, modularization and intelligence has brought new changes to the development of secondary equipment such as relay protection and control, and at the same time means that the testing methods for secondary equipment will undergo significant changes. [0003] At present, the test devices for digital substation relay protection on the market are mainly digi...
