Abstract: With the integration of a high proportion of inverter-based distributed energy resources into distribution networks, the system exhibits low inertia and strong fluctuation characteristics. The conventional feeder terminal unit (FTU) suffers from low frequency measurement accuracy, poor real-time performance, and lack of frequency-voltage emergency control strategies, making it difficult to cope with the security and stability control issues of distribution networks. Based on domestically produced multi-core CPU, this article has developed a new FTU device that takes into account frequency and voltage emergency control . By adopting the asymmetric multi-processing (AMP) platform architecture, dual-system operation of non-real-time and real-time tasks is realized, which improves the computing real-time performance and service scalability of the FTU. On this platform, the accuracy and real-time performance of frequency measurement are enhanced, and the logic function of frequency-voltage emergency control is implemented.
