Abstract

Sistem DC PLTGU Muara Tawar 240V DC terdiri dari baterai, penyearah dan inverter. Peralatan ini memerlukan perawatan rutin karena sistem DC merupakan sistem yang menyediakan daya cadangan jika terjadi gangguan listrik dan bertindak sebagai pengontrol pompa-pompa tertentu dalam mekanisme produksi. Kelalaian merawat perangkat secara teratur dapat mengakibatkan kerusakan pada perangkat dan mengganggu kinerjanya. Oleh karena itu, kami melakukan observasi langsung terhadap pemeliharaan sistem DC tersebut. Prosedur perawatan dilakukan dengan mengamati secara visual setiap tampilan perangkat dan membersihkan perangkat.

Abstract

Cooling Water Pump berfungsi sebagai penyuplai air untuk sistem pendinginan di PLTA Asahan 1 yang mendinginkan minyak dan udara. Sistem pendingin udara terdapat pada Generator Air Cooler, dan system pendingin minyak terdapat pada Thrust Bearing Oil Cooler, Turbine Guide Bearing Oil Cooler, Upper Generator Oil Cooler, dan Lower Generator Oil Cooler. Air pada sistem pendingin bersumber dari draft tube (pipa pembuangan) yang dipompakan oleh Cooling Water Pump. Air yang digunakan setelah pendinginan akan disalurkan kembali melalui sistem pemipaan menuju

Abstract

Marine Science Techno Park (MSTP) Jepara is a center of technology implementation aimed to encourage community economy development in the maritime sector. At present, Marine Science Techno Park (MSTP) Jepara’s electrical energy source is supplied by Perusahaan Listrik Negara (PLN), with coal-powered steam turbine generators as the main source of electrical energy generation. Therefore, a cleaner and more sustainable means of electrical energy generation is needed to fulfill the high energy demand. With this in mind, Universitas Diponegoro, as the proposer, in collaboration with MSTP Jepara, as the recipient, proposes the initiation of Hybrid Renewable Energy Systems (HRES) Power Plant construction as a way of obtaining an environmentally friendly and sustainable source of energy in this research as well as addressing the issues in the previous HRES simulations and implementations. This article will discuss various scenarios, their feasibility for implementation, and the economic returns gained from HRES installation on-site.
