Abstract
Pada tugas akhir ini, dilakukan simulasi pengaruh tiga kondisi instalasi saluran kabel laut tegangan tinggi, yaitu sub-sea laying, direct buried, dan pipe buried. Pengaruh dari kedua kondisi ini dianalisis menggunakan software desain grafis untuk memodelkan kabel laut dalam dua dan tiga dimensi. Selanjutnya, model isolator yang dihasilkan dimasukkan ke dalam software simulasi berbasis FEM (Finite Element Method) untuk melakukan analisis berdasarkan karakteristik instalasi tersebut. Dalam simulasi ini, dua efek utama yang diperhatikan adalah medan elektromagnetik dan radiasi termal. Simulasi medan elektromagnetik menunjukkan bahwa medan tidak mengalami perubahan signifikan pada kedua kondisi instalasi. Hal ini menunjukkan bahwa kabel berada dalam kondisi yang sempurna dan tidak mengalami kecacatan. Namun, hasil simulasi radiasi termal menunjukkan bahwa kondisi pipe buried menghasilkan kenaikan suhu tertinggi dibandingkan dengan kedua kondisi lainnya. Kabel yang dilindungi oleh pipa dan terletak di dasar laut mengalami kenaikan suhu yang lebih tinggi dibandingkan dengan kabel yang ditanam langsung di dasar laut atau dibiarkan melayang di dalam laut. Dengan demikian, simulasi ini memberikan pemahaman tentang pengaruh kondisi instalasi terhadap saluran kabel laut tegangan tinggi. Hasilnya dapat digunakan untuk memilih kondisi instalasi yang paling sesuai dengan kebutuhan sistem tenaga listrik, dengan mempertimbangkan efek medan elektromagnetik dan radiasi termal yang dihasilkan.

In this final project, a simulation of the effects of three conditions of high-voltage sea cable installation is carried out: sub-sea laying, direct buried, and pipe buried. The influence of these two conditions is analyzed using graphic design software to model submarine cables in two and three dimensions. Furthermore, the resulting insulator model is entered into simulation software based on FEM (Finite Element Method) to conduct an analysis based on the characteristics of the installation. The two main effects of this simulation are electromagnetic fields and thermal radiation. The electromagnetic field simulation shows that the field does not change significantly in both installation conditions. This indicates that the cable is in perfect condition and has no defects. However, the thermal radiation simulation results show that the pipe buried condition produces the highest temperature increase compared to the other two conditions. Cables protected by pipes and located on the seabed experience a higher temperature increase compared to cables buried directly on the seabed or left floating in the sea. Thus, this simulation provides an understanding of the effect of installation conditions on high-voltage marine cable lines. The results can be used to select the installation conditions that best suit the needs of the electric power system, taking into account the effects of the electromagnetic field and the resulting thermal radiation.
