Adha Pristian, Candra (2021) Kajian Stabilitas Sistem Islanding Distribusi Penyulang Pujon Dengan Adanya Pembangkit Tersebar Mikrohidro dan Angin. Sarjana thesis, Universitas Brawijaya.
Abstract
Penyulang Pujon adalah penyulang tipe radial yang diberikan pasokan daya listrik oleh Gardu Induk Sengkaling, Malang. Kajian lebih lanjut diperlukan untuk kestabilan sistem saat sistem diberi penambahan pembangkit tersebar dikarenakan dalam suatu sistem atau plant yang besar dimana lebih dari dua generator yang bekerja secara bersamaan, dapat menyebabkan kerugian yang besar jika kontinuitas penyaluran dayanya tidak stabil. Pada saat terjadi gangguan hubung singkat yang terjadi secara tiba-tiba dan dalam waktu yang cepat, maka acuan kestabilan transien dalam suatu sistem kelistrikan harus diperhatikan yaitu, dengan melihat respon frekuensi, tegangan dan sudut rotor pada sistem.Berdasarkan kajian penelitian sebelumnya didapatkan bahwa Penyulang Pujon dapat diberikan penambahan Pembangkit Listrik Tenaga Angin dengan kapasitas sebesar 2,5 MVA, dengan lokasi di Lapangan Songgokerto Kabupaten Batu. Sedangkan Pembangkit Listrik Tenaga Mikrohidro (PLTMH) Pujon sekarang ini telah dibangun dengan kapasitas 15 kVA, dan mempunyai potensi untuk ditambahkan pada Penyulang Pujon. Penelitian ini mengkaji kestabilan pada saat sistem diberikan penambahan Pembangkit Listrik Tenaga Angin dan PLTMH tersebut dengan menerapkan skema pengamanan (defence scheme) pada saat operasi islanding (island operation). Operasi islanding adalah mekanisme dimana terdapat pembangkit yang terpisah dari sistem distribusi, karena adanya gangguan hubung singkat pembangkit tersebut mampu menyuplai daya ke beban sesuai dengan kapasitasnya dan mampu mepertahankan kestabilan sistem jaringan distribusi pada saat grid terputus. Kata kunci: Kestabilan transien, operasi islanding, pembangkit tersebar, skema pengamanan, Pembangkit Listrik Tenaga Angin dan PLTMH.
English Abstract
The Pujon Feeder is a radial system that the electricity power is provided by the Sengkaling substation, Malang, East Java-Indonesia. the additiom of a DG requires further study, especially on the aspect of power system stability because addition of a DG with more than two generators working simultaneously can cause large losses if the continuity of the power supply is unstable. In the event when a short circuit disturbance occurs which happens spontaneously and in a brief moment, then the transient stability in an electrical system have references to be looked forward into which are the response of frequency, voltage, and rotor angle on the power distribution system. Based on previous research studies it was found that Pujon Feeder can be added by Wind Power Plant (WPP) with a capacity of 2,5 MVA, located at Songgokerto Field, Batu District. On the other hand, the Pujon Micro-Hydro Energy Power (MHEP) has been built with a capacity of 15 kVA, and has the potential to be added on the Pujon Feeder. This study examines the power system stability when the system is added with WPP and MHEP with a defense scheme during the islanding operation. The islanding operation is a mechanism when there was a DG isolated from the distribution system, due to short circuit disturbance the DG still providing power supply to the load in the capability of the DG so that the stability of the distribution network system remains in a good shape when the supply of the grid is none. To show the responses of the Pujon Feeder in the addition of WPP and MHEP in perspective of the steady state and dynamic analyses, 4 simulation is needed, which are: 1) the existing system; 2) Existing + WPP; 3) Existing + MHEP; and 4) Existing + WPP+ MHEP. The analysis shows that, based on steady state analysis, with the addition of DGs, the Pujon Feeder system has improved the voltage levels and decreased system power losses. The system power losses in condition 1 (existing system) were 0.416 MW (9,625%) and 0,246 MVAR (9,227%) while in condition 4 were 0.174 MW (3,150%) and 0.156 MVAR (5.570%). Furthermore, based on dynamic analysis for 3 phase balanced disturbance simulations and the duration of the disturbance applied over 150ms, the simulation results have shown that all response of frequency, voltage, and rotor angles are stable for all scenarios tested. For the simulation of 3 phase permanent disturbances which causes the generator to work in islanding operation mode, when in special condition, it is necessary to add three sectionalizers to the Pujon Feeder in order to make the frequency, voltage and rotor angle responses back to stable condition. Keywords: Transient stability, island operation, distributed generation, defence scheme, wind and micro-hydro power plant.
