Abstract

Akibat terjadinya gangguan pada salah satu unit pembangkit yang dioperasikan secara paralel dapat menyebabkan ketidakseimbangan daya yang dihasilkan pembangkit dan dibutuhkan beban mengakibatkan pemadaman total (blackout) dan kerugian besar bagi industri. Untuk mencegah hal ini, penelitian ini mengkaji penerapan sistem load shedding menggunakan metode logika fuzzy pada sistem kelistrikan PT. Riau Andalan Pulp and Paper, yang memiliki dua generator utama dengan kapasitas masing-masing 135 MW dan 337 MW. Sistem load shedding dirancang untuk merespons gangguan dengan melepas beban sesuai tingkat prioritas yang ditentukan, serta memastikan beban prioritas tinggi tetap aktif. Penelitian ini menggunakan protokol komunikasi IEC 61850 dengan pengiriman sinyal GOOSE dan rata-rata waktu pengiriman 44,24 ms. Dua variabel input digunakan dalam logika fuzzy: besaran daya beban dan waktu penggunaan, dengan variabel output berupa lima tingkat prioritas: sangat rendah, rendah, sedang, tinggi, dan sangat tinggi. Hasil penelitian menunjukkan bahwa sistem load shedding dapat menyeimbangkan daya generator dan beban selama gangguan, dengan beban prioritas rendah dilepas terlebih dahulu. Pada percobaan, beban dengan prioritas paling rendah adalah load 4 dengan daya aktif 9,791 MW, sedangkan beban prioritas tertinggi adalah load 10 dan 19. Pengujian pertama menghasilkan 4 beban yang dilepas, sedangkan pengujian 2 menghasilkan 11 beban yang dilepas. Implementasi sistem ini diharapkan meningkatkan efisiensi dapat operasional dan mengurangi kerusakan pada peralatan kelistrikan di PT. Riau Andalan Pulp and Paper.

============================================================

Disturbances in one of the generating units operating in parallel can cause an imbalance between the power generated and the load required, resulting in a total blackout and significant losses for the industry. To prevent this, this study examines the implementation of a load shedding system using the fuzzy logic method in the electrical system of PT. Riau Andalan Pulp and Paper, which has two main generators with capacities of 135 MW and 337 MW, respectively. The load shedding system is designed to respond to disturbances by shedding loads according to predetermined priority levels, ensuring that high-priority loads remain active. This study uses the IEC 61850 communication protocol with GOOSE signal transmission and an average transmission time of 44.24 ms. Two input variables are used in the fuzzy logic: load power magnitude and usage time, with the output variable consisting of five priority levels: very low, low, medium, high, and very high. The results indicate that the load shedding system can balance generator power and load during disturbances, with low-priority loads being shed first. In the experiments, the lowest priority loads were load 4, with active powers of 9,791 MW, respectively, while the highest priority loads were load 10 and load 19. The first test resulted in the shedding of 4 loads, while the second test resulted in the shedding of 11 loads. The implementation of this system is expected to improve operational efficiency and reduce damage to electrical equipment at PT. Riau Andalan Pulp and Paper.
