The Design And Realization Of The Power Line Feeder Monitoring Unit

Considering kinds of electrical circuit malfunction and the testing need of distribution automation, this paper completes the study on testing electrical circuit malfunction by utilizing the knowledge of computer technique, data transmission technology, control technique and modernization network communication. This paper focuses on describing the principle of distribution automation and how to establish model of distribution automation and its meaning, besides, it describe testing scheme and transition condition about malfunction estate and refer to new technology of malfunction testing, this paper also analyzes the hardware configuration for malfunction testing equipment FTU, which mainly includes introduction, kind, present state hardware configuration, software idea and mathematical model.Finally this paper explains the function of FTU. As the rapid development of national economy, the reliability of power supply is required highly. I believe we must develop a new testing equipment, which has the character of function perfection, technology intelligence, communication integration, structure modularity, design standardization, volume miniaturization and product serialization.
