Abstract
PT PLN Indonesia Power Suralaya PGU merupakan salah satu pembangkit listrik dengan kapasitas terbesar di Indonesia. Oleh karena itu, diperlukan sistem cadangan seperti baterai untuk menjaga pasokan listrik dalam kondisi darurat. Penelitian ini bertujuan untuk memantau kondisi baterai agar selalu dalam kondisi optimal. Metode yang digunakan adalah Constant Current Dummy Load (CCDL), yang dilakukan dengan memberikan beban arus konstan sebesar 44,1 A selama 10 jam kepada baterai. Hasil pengujian menunjukkan penurunan nilai tegangan dengan tegangan total akhir sebesar 111,53 V. Selain itu, penurunan nilai densitas elektrolit juga terjadi selama pengujian, dengan nilai akhir sebesar 1,11 Kg/L. Suhu baterai meningkat hingga 39°C pada akhir pengujian. Kapasitas pengosongan baterai tidak jauh berbeda dengan kapasitas pengisian sebesar 430,4 Ah, membuktikan bahwa efisiensi baterai sangat baik sebesar 97,6%. Berdasarkan pengujian, baterai akan menyentuh batas minimum tegangan 108 V pada jam ke-14,11. Sedangkan, dengan arus beban real sebesar 68 A, baterai mampu menyuplai beban sistem selama 6,48 jam. Mengacu pada data hasil penelitian, dapat disimpulkan bahwa baterai 125 V pada PT PLN Indonesia Power Suralaya PGU Unit 2 berada dalam kondisi sangat baik. PT PLN Indonesia Power Suralaya PGU is one of the largest power plants in Indonesia. Therefore, a backup system such as batteries is needed to maintain the power supply during emergency conditions. This study aims to monitor the condition of the batteries to ensure they remain in optimal condition. The method used is the Constant Current Dummy Load (CCDL), conducted by applying a constant current load of 44.1 A for 10 hours to the batteries. The test results showed a decrease in voltage, with a final total voltage of 111.53 V. Additionally, a reduction in electrolyte density was observed during the test, with a final value of 1.11 Kg/L. The battery temperature increased to 39°C by the end of the test. The discharge capacity of the batteries are not much different than the charging capacity of 430,4 Ah, proving that the battery efficiency is excellent at 97,6%. Based on the test, the battery will reach the minimum voltage limit of 108 V at 14.11 hours. Meanwhile, with a real load current of 68 A, the battery can supply the system load for 6.48 hours. Referring to the test data, it can be concluded that the 125 V batteries at PT PLN Indonesia Power Suralaya PGU Unit 2 are in excellent condition.
