Abstract
Pipa pesat merupakan saluran penghubung antara bak penenang dengan turbin pada rumah pembangkit. Meminimalisir kehilangan energi pada pipa pesat sangat penting untuk mengoptimalkan bangkitan energi listrik. Tujuan penelitian ini adalah melakukan optimasi diameter dan tebal pipa pesat untuk mencari hasil yang paling efisien, yang dikaji dari aspek hidrolika dan biayanya. Metode pemilihan pipa pesat yang optimal dapat ditentukan berdasarkan hubungan secara empiris, antara berbagai formula dari diameter dan tebal pipa pesat yang dinilai terhadap energi yang dihasilkan serta harga pipa pesat itu sendiri. Hasil penelitian menunjukkan bahwa besar diameter berbanding lurus dengan besar energi yang dihasilkan dan harga pipa pesat. Berdasarkan perbandingan, didapatkan diameter optimum pipa pesat sebesar 0,45 meter dengan tebal 0,0018 meter yang dihitung menggunakan formula dari Moffat, serta daya bangkitan sebesar 52,16 kW dan energi sebesar 456.914,33 kWh per tahunnya dengan harga pipa IDR 3.610.900 per meter pipa pesat. Penstock is the connecting channel between the forebay and the turbine in the power house. Minimizing the energy loss in the penstock is very important to optimize the generation of electrical energy. The purpose of this research is to optimize the diameter and thickness of penstock to find the most efficient results, which are examined from the aspects of hydraulics and costs. The optimal method of penstock selection can be determined based on the empirical relationship between the various formulas of the diameter and thickness of the penstock as assessed by the energy produced and the price of the penstock itself. The results showed that the diameter was directly proportional to the amount of energy produced and penstock price. Based on the comparison, the optimum diameter of the penstock is 0,45 meters with a thickness of 0,0018 meters which is calculated using the formula from Moffat, as well as a generation power of 52,16 kW and energy of 456.914,33 kWh yearly with the price of IDR 3.610.900 per meter penstock pipe.
这条抽油管是消声器和发电机涡轮机之间的连接管道。将气管的损失降到最低是充分利用电能的关键。该研究的目的是对直径和管道厚度进行最大的利用,以确定水力学和成本方面的最有效成果。最佳的快速选择方法可以通过经验来决定,从直径的不同配方到生产的快速管道的厚度以及快速管道本身的价格。研究表明,直径与由此产生的巨大能量成正比,价格迅速。相比之下,它的最佳直径为0.45米,厚度为0.0018米,使用的是莫夫特配方计算出来的,其复苏能力为每年456,914.33千瓦时,其价格为23英尺(3610900米)的IDR管。Penstock是连接海湾和turbine之间的电源。在penstock中最小化掉的能量对乐观一代电子能源非常重要。这项研究的目的是利用生命的直径和存量来找到最值得尊敬的结果匹配的最佳方法可以建立在不同强度强度的度量和度量之间的经验关系上结果表明,其直径与能源生产和股票价格的比例相反。最佳直径》改编自《不那么可怜,penstock是45米的with a thickness 0.0018从莫法特米,这是用的计算公式,as well as a generation 52.16 kW的电力和能源的456.914,33千瓦时yearly每米penstock with the price of IDR 3610900管。
