Abstract
Transformasi gardu induk eksisting menuju gardu induk digital merupakan salah satu langkah strategis dalam mendukung digitalisasi sistem tenaga listrik nasional. Salah satu teknologi kunci dalam transformasi ini adalah implementasi Process bus berbasis protokol IEC 61850, yang menggantikan sistem komunikasi sinyal eksisting (hardwired) dengan jaringan digital berbasis Ethernet atau fiber optic. Teknologi ini memungkinkan pengiriman sinyal proteksi dan pengukuran secara real-time menggunakan protokol seperti GOOSE dan Sampled Measured Values (SMV), sehingga mampu mengurangi jumlah kabel fisik, mempercepat waktu respon, dan meningkatkan fleksibilitas sistem.
Penelitian ini bertujuan untuk merancang dan menguji simulator rele control panel berbasis Process bus IEC 61850, guna mengevaluasi efisiensi penggunaan kabel dan performa waktu respon proteksi pada sistem gardu induk digital. Pengujian dilakukan melalui pembandingan antara sistem eksisting hardwired dan sistem digital Process bus, dengan fokus pada dua fungsi proteksi utama, yaitu Overcurrent Definite Time (OCR) dan Auto Reclosing (AR). Hasil pengujian menunjukkan bahwa sistem Process bus mampu mengurangi penggunaan kabel hingga 42,86%. Efisiensi ini dicapai karena penggunaan kabel fiber optic multimode yang mendukung transmisi data simultan melalui satu jalur, sehingga satu kabel Ethernet dapat menggantikan puluhan kabel sinyal analog pada sistem eksisting. Selain itu, sistem Process bus juga menunjukkan waktu respon yang lebih cepat dan stabil dibandingkan sistem konvensional, baik pada fungsi OCR maupun AR. Dari hasil tersebut, dapat disimpulkan bahwa implementasi Process bus tidak hanya menawarkan efisiensi instalasi secara fisik, tetapi juga meningkatkan keandalan dan kecepatan sistem proteksi. Proyek Akhir ini mendukung pemanfaatan teknologi IEC 61850 sebagai fondasi dalam pengembangan gardu induk modern yang digital, efisien, dan responsif, sesuai arah kebijakan RUPTL 2021–2030.

The transformation of existing substations into digital substations is one of the strategic steps in supporting the national power system digitalization. A key technology in this transformation is the implementation of the Process Bus based on the IEC 61850 protocol, which replaces the conventional hardwired signaling system with a digital communication network using Ethernet or fiber optic cables. This technology enables real-time transmission of protection and measurement signals using protocols such as GOOSE and Sampled Measured Values (SMV), thereby reducing the number of physical cables, improving response time, and enhancing system flexibility. This research aims to design and test a relay control panel simulator based on the IEC 61850 Process Bus, in order to evaluate cable efficiency and protection response time performance in a digital substation system. The tests were conducted by comparing the existing hardwired system with the digital Process Bus system, focusing on two main protection functions: Overcurrent Definite Time (OCR) and Auto Reclosing (AR). The results show that the Process Bus system can reduce cable usage by up to 42.86%. This efficiency is achieved through the use of multimode fiber optic cables, which support simultaneous data transmission over a single path, allowing one Ethernet cable to replace dozens of analog signal cables in the existing system. Additionally, the Process Bus system demonstrated faster and more stable response times compared to the conventional system, in both OCR and AR protection functions.
From these results, it can be concluded that the implementation of the Process Bus not only offers physical installation efficiency but also improves the reliability and speed of the protection system. These final project support the adoption of IEC 61850 technology as a foundation for developing modern substations that are digital, efficient, and responsive, in line with the 2021–2030 RUPTL policy direction.
