Abstract
Beban-beban non-linier pada jaringan distribusi menimbulkan fenomena harmonisa. Harmonisa menyebar ke seluruh jaringan distribusi sistem tenaga listrik dan menyebabkan gelombang arus dan tegangan tidak sinusoidal. Keadaan ini mengganggu kinerja peralatan listrik. Untuk itu alasan tersebut, jaringan distribusi diperlukan monitoring fenomerna harmonisa agar besarnya sesuai dengan standard. Tujuaanya yaitu menjaga kualitas daya dari sistem tenaga listrik. Studi yang membantu mengestimasi nilai harmonisa yaitu menggunakan Harmonic State Estimation.
Pada tugas akhir ini menggunakan analisis aliran daya backward-forward sweep pada sistem distribusi tenaga listrik radial seimbang (Balanced RDS) dan analisa aliran daya harmonisa (HLF) yang digunakan sebagai data pengukuran untuk Harmonic State Estimation (HSE). Metode Singular Value Decomposition digunakan untuk menyelesaikan persamaan HSE. Metode ini menghasilkan nilai estimasi harmonisa dan uji observabilitas untuk identifikasi suatu sistem. Hasil analisis HSE diimplementasikan ke dalam Sistem Informasi Geografis (GIS) Smallworld PLN Area Distribusi Jawa Timur.
Berdasarkan hasil simulasi dan analisis, metode SVD mampu mengestimasi nilai harmonisa dengan error yang kecil yaitu sebesar 0.05%. Metode ini juga menunjukkan bahwa penggunaan Phasor Measurement Unit (PMU) dapat dikurangi dan mampu menguji observabilitas suatu sistem. Sehingga metode ini cocok digunakan untuk membantu monitoring jaringan distribusi tenaga listrik berbasis GIS. ========== Non
-linier loads in power distribution system cause harmonic phenomenon. Harmonic spread widely in power distribution system and make non sinusoidal current and voltage waveform. This condition distrubs electrical equipment performance. For that reason, power
distribution system needs harmonic phenomenon monitoring so the value is agree with harmonic standard. The goal is to keep power quality in power system. The study that helps to estimate harmonic value is using Harmonic State Estimation. In this thesis using backward-forward sweep power flow in balanced radial power distribution system (B
alanced RDS) and Harmonic Load Flow (HLF) are used as measurement data to solve Harmonic State Eestimation (HSE)
equation. This method produces harmonic estimated value and
observability test to identify a system. The result of HSE is implemented in Geographic Information System (GIS) Smallworld PLN East Java Distribution Area. According to the result of simulation and analysis, SVD method
can estimate harmonic value with 0.05% small error. This method shows that Phasor Measurement Unit (PMU) can reduced and the observability of system can examined. So, this method is suitable for helping power distribution system monitoring based on GIS.
