Abstract

Tapping the transmission lines with capacitive coupling is an alternative to supply the electricity for isolated regions with energy requirment below 50 kW. This option is more economical option compared to other alternatives such as makes substation, long distribution lines or small power house.The capacitive coupling actually a capacitive voltage divider that steps the voltage of transmission level down to the distribution level. Inductor must be connected to primary side and secondary side of the distribution transformer in order to compensate the resonance of capacitive load. Abstract in Bahasa Indonesia : Salah satu alternatif untuk dapat memberikan sumber listrik pada daerah terpencil yang membutuhkan daya relatif rendah dan dilalui oleh saluran transmisi adalah dengan melakukan penyadapan daya yang terdapat pada saluran transmisi dengan menggunakan kopling kapasitif.Kopling kapasitif yang digunakan membentuk suatu pembagi tegangan kapasitif yang berguna untuk menurunkan tegangan dari level tegangan transmisi ke level tegangan distribusi. Pemasangan Induktor yang dihubungkan pada sisi primer dan sisi sekunder transformator distribusi berfungsi untuk mengkompensasi resonansi yang timbul akibat adanya beban kapasitif.Pada tulisan ini dibahas kondisi sistem pada saat terjadi penyadapan baik saat transient maupun steady state dengan simulasi. Kata kunci : transmisi, kopling kapasitip, pembagi tegangan kapasitif.

Abstract

The persistent reliance on fossil fuels for energy will yield enduring adverse effects on the tourism sector, particularly the hotel industry. Wind energy represents a renewable electricity source that can facilitate the transition of small-scale hotels to clean energy. The main objective of this research is to propose a methodology for evaluating the potential of wind energy to support sustainable tourism in developing nations, specifically in fulfilling the electricity requirements of small hotels. This study aims to assess and compare the potential contribution of small wind turbines to hotel energy demand by modelling a historical hourly wind dataset spanning ten years (2011-2020) and forecasting a portion of the dataset. This research selected three sites in Indonesia exhibiting varying wind energy potentials: Tepus District in Gunung Kidul Regency, Losari Beach in Makassar City, and Nusa Penida Island in Bali. This study utilises multiple linear regression to examine the impact of external variables on wind speed, and it applies Seasonal Autoregressive Integrated Moving Average (SARIMA) and Holt-Winters Exponential Smoothing (HWES) for wind speed forecasting in these three locations. The hourly and daily interval datasets analysis reveals a weak correlation between external factors and wind speed, with the HWES method identified as the most appropriate approach for modelling and forecasting wind speed, surpassing the SARIMA model by 0.309 RMSE. Forecasting results indicate that a 30-kW wind turbine could supply 8.8 - 35.3% of a small hotel's electricity consumption, depending upon the occupancy rate.
