Application of Second Generation Wavelet Transform for SEIG Load Transient Detection

Abstract

Self-excited induction generator (SEIG) is preferred in isolated and remote power generating systems. But the major problem associated with SEIG is change in voltage and frequency during loading condition. For the development of simple voltage and frequency controller it is essential to detect the load transient in less time using less hardware. In this paper Second Generation Wavelet Transform (SGWT) and Discrete Wavelet Transform (DWT) are used for SEIG to detect load transient. It is observed that SGWT is more powerful and capable than DWT. Its computation time to detect load transient is less and also requires less hardware in real time.
