Title The design of the emulation device of the intelligent terminal of the intelligent substation based on NI platform
Abstract
At present our country is developing the smart grid technology, including the construction of intelligent substation is an important part of the smart grid construction. Intelligent digital substation secondary system main characteristic is data collection, information interaction network.Compared with the traditional substation, intelligent substation secondary loop improvement is significant,and the rational. In the face of new trip of secondary system control circuit, the function of the intelligent terminal is particularly prominent.
By the completion of this article, I detailed master transmission and reception GOOSE messages, as well as the structure of GOOSE messages. Familiar with the structure and use NI CRIO platform, in-depth understanding of the role and working principle of intelligent terminals. In the master LabVIEW programming method, based on the completion of the simulation-based intelligent substation intelligent terminal device software NI platform implementations, and platform based on NI CRIO complete hardware design based on the completion of the Software. And functional simulation apparatus realized verified. Intelligent substation intelligent terminal emulation device through the NI platform-based design, complete GOOSE message capture and parsing. Eventually cultivate the ability of their own programming and simulation, and the ability to apply the knowledge to independently analyze and solve problems.
