Abstract

ABSTRAK Isolator merupakan komponen yang penting dijaga keandalannya dalam sistem transmisi dan distribusi tenaga listrik. Isolator rentan mengalami kegagalan akibat lingkungan, karena terpapar langsung kondisi dimana isolator tersebut terpasang. Salah satu jenis isolator yang sering digunakan adalah bahan keramik, dimana memiliki kelebihan diantaranya kekuatan mekanik yang cukup handal. Namun kekurangan isolator jenis ini adalah sifat permukaannya yang hidrofilik, yaitu mudah menyerap air sehingga bila digunakan pada kelembaban tinggi cenderung memicu timbulnya arus bocor. Arus bocor merupakan parameter penting pada isolator karena sering menjadi penyebab kegagalan isolator. Untuk mengetahui seberapa besar pengaruh kondisi lingkungan terhadap arus bocor, dilakukan pengujian terhadap isolator keramik dalam waktu 24 jam. Data arus bocor diambil setiap 3 jam untuk melihat perubahannya berdasarkan perubahan kelembaban, dan suhu lingkungan. Hasilnya didapat bahwa semakin tinggi kelembaban udara, dan semakin rendah suhu lingkungan maka arus bocor semakin tinggi. Hasil penelitian ini dapat dijadikan acuan untuk mengantisipasi kegagalan isolator keramik akibat arus bocor sehingga keandalan sistem tenaga listrik dapat terjaga. Kata kunci: Isolator keramik, Lingkungan, Kelembaban, Suhu. ABSTRACT Isolator is an important component that must be maintained to keep electric power transmission and distribution system reliability. Isolators are susceptible to failure due to the environment, because they are directly exposed to conditions where the insulator installed. Ceramic insulator is one type of isolator that is often used, which has advantages including mechanical strength that is quite reliable. However, the lack of this type of isolator is its hydrophilic surface, which is easy to absorb water so that when used at high humidity tends to trigger a leakage current. Leakage current is an important parameter in an insulator because it can be a cause due to insulator failure. To find out how environmental conditions impact on leakage currents along day, a ceramic isolator is tested within 24 hours. Leakage current data is taken every 3 hours to see the changes based on changes in humidity, and ambient temperature. The result is the higher humidity of the air, and the lower ambient temperature, can make insulator leakage current rise up. The results of this study can be used as a reference to anticipate the failure of ceramic insulators due to leakage currents so that the reliability of the electric power system can be maintained. Keywords: ceramic insulator, environtment, humidity, temperature.

Abstract

Based on the emergence of increasingly advanced technology, the conventional power grid can be upgraded to a smart grid by adding bidirectional communication, computer algorithms, and equipment that uses artificial intelligence (AI). A smart grid is a revolution in the current electricity network that can control the two-way generation and transmission process by utilizing an intelligent system so that the distribution of electric power can be handled optimally and in real time. The challenge of the smart grid is that there are distributed generators and microgrids that must be controlled in real time with rapidly changing loads. To meet these criteria, several points are proposed, i.e., finding an effective procedure to construct self-healing capability; developing a protection system based on AI; and proposing a systematic procedure to realize self-healing and protection systems with the help of a multi-agent system (MAS). Multi-agent systems are one of the AI approaches. Each agent can work independently and can also communicate with one another and with other devices on the network. Agents used as models can be classified into several categories, such as grid component agents, distributed resource agents, end-user agents, failure control agents, data analysis agents, and graphical visualization agents.
