Design and Development of Man-Machine Interface for UPFC-FCL

Unified power flow control with fault current limiting (UPFC-FCL) is a novel FACTS device which can protect the series converter from being destroyed by fault current of the system. In this paper, man-machine interface (MMI) based on NI Measurement Studio with Microsoft Visual Studio is proposed, which can monitor the status and adjust the parameters of UPFC-FCL when it is running. The data is transferred between MMI and controller via USB. The test results indicate that the MMI illustrated in this paper has a friendly interface with rich functions such as status monitor, running control, fault feedback, operation record and data analysis.
