Abstract—Smart grid applications have been extended to perform supervisory functions within a short and efficient time. Insecure operating conditions are likely to happen in power systems. Reducing the risk associated with this condition, adaptive countermeasures and self- healing actions are made using the infrastructures of the smart grids. Real time transient stability assessment (TSA) is classified into this kind of applications. Corrective control actions could be taken based on the post-fault rotor angle deviations. In this paper, a novel real-time Digital signal processing (DSP) based load angle measurement instrument for synchronous generators is discussed. This real-time instrument designed for high precision online applications. In this approach Input signals contain rotor’s shaft position and zero-crossing of generator terminal voltage are applied to a DSP board to achieve the online load angle. The proposed load angle measuring instrument is installed and used in many power plants in Iran. The experimental results demonstrate the high accuracy and fast response of the proposed instrument.
