Abstract

Small-disturbance angle stability or low-frequency oscillation is one of the important stability in the power system. Although damper windings and power system stabilizer (PSS) have been proved to stabilize and improve small-disturbance angle stability. However, due to increasing demand in the recent years, adding redox flow batteries (RFB) as additional devices is crucial. This paper investigates, the utilization additional devices called RFB to enhance the small-disturbance angle stability in the power system. Furthermore, ant colony optimization (ACO) method is used to tune RFB parameter. To analyze the stability improvement on the power system, single machine infinite bus is used as a test system. Eigenvalue and time domain simulation is used to examine the behavior of the investigated system. From the simulation, it is found that by installing RFB in the system, the small-disturbance angle stability of power system is improved and ACO can be a solution of tune RFB parameter.

Abstract

Makalah ini menyajikan simulasi untuk menentukan daya listrik yang dihasilkan Pembangkit Listrik Tenaga Panas Bumi (PLTPB) bersiklus biner dengan menggunakan beberapa jenis fluida kerja. Fluida kerja berfungsi untuk memanaskan uap basah bertemperatur rendah yang dihasilkan sumur panas bumi. Fluida kerja  yang digunakan adalah R-12, R-114, R-134a, dan R-245fa. Hasil simulasi berupa grafik temperatur terhadap entropi, tekanan terhadap entalpi, temperatur inlet turbin terhadap efisiensi termal, temperatur inlet turbin terhadap laju alir fluida kerja, dan daya listrik terhadap variasi fluida kerja. Fluida kerja yang memiliki kemampuan terbaik untuk meningkatkan daya listrik adalah R-134a, dengan menghasilkan daya listrik maksimum sebesar 1,349 MW.   Kata kunci: siklus biner, efisiensi termal, entropi, entalpi, laju alir
