Makalah ini mendiskusikan tentang impelementasi DVR pada saluran penyulang Pujon dengan kompensasi tegangan Sag/Dip. Tegangan Dip penyebabnya sering akibat dari gangguan hubung singkat 1 fasa ke tanah. Tegangan Dip membuat tripping dan kerusakan peralatan beban yang menjadi permasalahan yang harus diatasi. Implementasi DVR digunkana untuk mengkompensasit tegangan Dip. Metode kontrol ANN diusulkan untuk mengatur kinerja DVR dalam mengkompensasi tegangan Dip. Hasil simulasi menunjukkan dengan implementasi DVR pada saluran penyulang Pujon mampu mengkompensasi tegangan Dip sebesar rata-rata 0.97% dari gangguan hubung singkat 1 fasa ke tanah dengan persentase penurunan tegangan pada fasa R sebesar 50%-70%.

“…The statistical parameters of wavelet coefficients like mean, median, SD, absolute value etc. can easily represent Daubechies (db), the mother wavelet function (Bollen, 2000;Caicedo et al, 2011;IEEEIAS, 1997). These feature extraction techniques will help to reduce the dimension of sampled signal and thereby reducing the computation time and increasing accuracy is demanded.…”

“…A sag in a transmission line affects sensitive equipment up to hundreds of kilometers away from the fault [3]. Most voltage sags do not go below 50 percent of the nominal voltage, and they normally last from 3 to 10 cycles or 50 to 170 milliseconds [4].…”

Voltage sag is one of the most critical power quality problems. This paper calculates voltage sag propagation through YNd11 and Dyn11 winding connected transformers in series using symmetrical components, thus obtaining the voltage transfer matrix. Then the voltage sag propagation of single line-to-ground fault is computed using the transfer matrix. Simulation result proves the correctness of the analytical calculation, providing reference for the further study of voltage sag influence and estimation.
