Pengaruh Masuknya Penambahan Pembangkit Baru Kedalam Jaringan 150 KV pada Kapasitas Circuit Breaker

This study aimed to obtain the appropriate capacity circuit breaker on the electric power system of Riau using bus impedance matrix method in determining the flow of short circuit in the electric power system of Riau. This research was conducted in two conditions, namely the current state (exsisting) and the conditions at the time of entry of a new generation into the electricity system interconnection network Riau region in this regard Tenayan power plant with a capacity of 2x110 MW.The results showed that the capacity of the circuit breaker that is currently installed on the electrical system Riau region is still larger than the three-phase short-circuit current simteris that may occur at this time of 12,375kA and at the time of entry of a new generation of 13,215kA so it can be said that the electrical system Riau region still able to withstand short circuit currents that may occur at the time of entry of the power supply from new power plants that have been planned.Keyswords: capacity circuit breaker, circuit breaker, short circui

Peningkatan Akurasi dalam Prakiraan Beban Listrik Jangka Pendek Menggunakan Data Temperatur

Temperature changing has affected to the electrical load consumption. It has considered in the calculation of short-term load forecasting. In this study, ANFIS method was used to forecast short-term load using historical data of electrical load and temperature. From the testing process, the MAPE value has obtained during the procces for daily bunch from Monday to Sunday and Public Holiday is included, i.e. 8.567%; 5.013%; 5.341%; 4.214%; 7.741%; 6.635%; 6.875% and0.022689%, respectively. The addicting of temperature data buffering has proven that forecasting accuracy is increased

Peningkatan Kualitas Jaringan Distribusi Tegangan Menengah dengan Optimasi Konfigurasi

Optimalitation of distribution line configuration on 20 Kv case for reconfiguration of distribution line without changed load sytem but with setting or regulate of switch in the feeder. In this case purpose is reduce losses in feeder.In this case, did in IEEE 69 bus type distribution line analysis that consist of 1 head transformer from relay station, 73 of lines, 5 of tie lines, 69 switch and 8 lateral

Analisa Kebutuhan Kapasitas Kapasitor Bank untuk Menjaga Pasokan Tegangan Operasi pada Bus Pompa Motor HCT Duri

PT. Chevron is one of the largest oil companies in the world. To be able to do maximum production, PT. Chveron need to make sure all goes well with the production facilities. One of the important production facilities is the delivery pumping motor. Duri operation area has 7 pumping motors to be installed with capacity of 550HP each of them. Each of individual pumping motor requires 4,16 kV which supplied by 13,8 kV of distribution network Prior to the installation, it is necessary to have a study to anticipate drop voltage or overvoltage case. This paper proposes capacitor banks installation approach. The approach uses several trial errors in the placement of capacitor in the respective bus within distribution network. The ETAP simulation result shows 4 buses with following configuration i.e bus 1 and bus 2 with 600 kVar, in the other case bus 3 and bus 4 with 300 kVar
