Abstract

Monitoring sistem tenaga listrik dilakukan agar kontinyuitas penyaluran tenaga listrik tetap terjaga. Geographic Information System (GIS) dapat digunakan untuk monitoring suatu sistem. Parameter yang dimonitoring salah satunya adalah tegangan. Untuk mendapatkan parameter tersebut dibutuhkan Phasor Measurement Unit (PMU), namun harga PMU sangat mahal apabila pada setiap bus dipasang PMU. Pengurangan PMU harus dilakukan untuk mengurangi biaya. Metode Binary Integer Linear Programming (BILP) digunakan untuk mengurangi jumlah alat pengukuran. Pada bus yang tidak terpasang alat pengukuran akan digunakan metode Extended Branch Current Distribution System State Estimators (Extended BC-DSSE). Dengan Metode Extended BC-DSSE ini parameter tegangan pada bus yang tidak terpasang alat pengukuran bisa diketahui. Selanjutnya parameter tegangan tersebut dapat ditampilkan di GIS untuk tujuan monitoring. Metode BILP dapat mengoptimalkan jumlah PMU menjadi 64,1% dari total PMU semula sehingga biaya menjadi berkurang. Parameter tegangan yang diestimasi menggunakan metode Extended BC-DSSE sangat akurat dengan error paling besar 0,2155% jika dibandingkan dengan running ETAP. Monitoring dilakukan melalui GIS yang mana pada tiap busnya dapat dilihat parameter tegangan. ================================================================================================================== The monitoring of electrical power system was used to maintain continuity of electrical power distribution. Geographic Information System (GIS) can be used to monitor a system. Electrical voltage is one of parameters that has to be monitored and to get this parameter , the engineer will use Phasor Measurement Unit (PMU) which costs a lot of money if this PMU wanted to be installed on every bus. PMU reduction has to be done to cut down the cost. Binary Integer Linear Programming (BILP) method was used to cut down the measurement tool amount. Extended Branch Current Distribution System State Estimators (Extended BC-DSSE) method will be used on the measurement tool that wasn’t installed on bus. Using this Extended BC-DSSE method, the electrical voltage parameter on the uninstalled measurement tool bus could be discovered. Furthermore, the electrical voltage parameter could be featured on GIS for monitoring purpose. BILP method can optimize the PMU number to 64,1% of earlier PMU, that can lessen the cost. Estimated electrical voltage parameter using Extended BC-DSSE method is very accurate with the result as the biggest error is 0,2155% compared to running ETAP. Electrical voltage parameter on each bus can be monitored by GIS.
