dc.description.abstractThis paper presents the dynamic analysis results of a system event in Thailand power network using a wide-area monitoring system based on synchronized phasor measurement units (PMUs). The salient feature of the proposed monitoring system is the convenient installation of PMU at 220V wall power outlets. The event considering here is a 80 MW load transferring from Thailand to Malaysia systems through a weak 115 kV tieline. To perform load transferring, a synchronization between both systems is required. This causes a problem of frequency oscillation in a southern area of Thailand. Besides, this event severely excites the inter-area oscillation in a 230 kV tie-line between central and southern areas of Thailand. Analyzed results based on discrete wavelet decomposition and short-time Fourier Transform provide valuable information of the system dynamic behavior in both frequency and time domains. © 2007 RPS.
