Penempatan Phasor Measurement Unit untuk Menentukan Prediksi Margin Kestabilan Tegangan

Levin Halim, Nanang Hariyanto, Muhammad Nurdin

Abstract


Perkembangan sistem tenaga dalam pembuatan transmisi baru dan fasilitas pembangkitan sistem tenaga listrik telah dibebani lebih besar daripada biasanya. Sebagai konsekuensinya, banyak sistem tenaga yang mengalami permasalahan tegangan yang pada akhirnya akan memicu ketidakstabilan tegangan. Makalah ini membahas penempatan phasor measurement unit (PMU) dengan menggunakan integer linear programming untuk penentuan prediksi margin kestabilan tegangan (voltage stability margin - VSM) dengan didasarkan pada pengukuran lokal yang memakai ekuivalen Thevenin untuk representasi sistem. Penempatan PMU dipilih sedemikian rupa dengan algoritme integer linear programming tersebut sehingga dapat ditentukan phasor tegangan dan arus pada setiap bus pada sistem tenaga listrik. Data-data yang diperoleh, berupa phasor tegangan dan arus pada setiap bus, dipakai untuk perhitungan prediksi margin kestabilan tegangan.
