Abstract

This paper presents a digital signal processor based prototype instrument to provide real-time analysis of power disturbances that can be used to perform quick power quality monitoring. The proposed instrument uses the Texas Instrument TMS320C6711DSP starter kit with a TIADS8364EVM 250-kHz, 16-bit, 6-channel and an analog digital converter mounted on the daughter card. For real-time analysis of power disturbances, the continuous wavelet transform is used to detect different types of disturbances such as voltage sag, swell, transient and harmonics. The results of analysis show that the implementation of continuous wavelet transform algorithm in DSP-based system provides accurate and fast detection of power quality disturbances.
