Prakiraan Kebutuhan Energi Listrik di Wilayah PT. PLN (Persero) Rayon Bangkinang Menggunakan Prangkat Lunak LEAP (Long-Range Energy Alternatives Planning System)

The growth amount of Kampar Regency resident is 14.57%, is growth has increased the need of electrical energy. Therefore to make the electrical consumption supply at Kampar Regency sustainable, it needs electrical energy consumption forecast. This paper purposes electrical demand forecasting for 2016-2025 to predict the level of consumption (demand) of electricity per sector tariffs for PT. PLN (Persero) Rayon Bangkinang regency. Data required for this research was included PLN data on the number of customers and energy consumption in each tariff level sub period 2014-2016 and data of alternative energy potential (Biogas) in kampar regency is utilized as a source of electrical energy. The mechanism of forecasting is composed by following processes, firstly demand is calculated based on the amount of electrical energy consumption activity and the amount of electrical energy consumption per activity (energy intensity). Next, once those data is obtained and it is calculated and analyzed by LEAP (Long-range Energy Alternatives Planning System). In the end the result will compared to data from PT. PLN. In 2016, base PLN data was 17.868 MWh. In other hand, the data from LEAP software was 17.868 MWh. The difference is only on energy consumption of one sector while in household sector from PT. PLN was 12.844 MWh, but data obtained from LEAP software was about 12.845 MWh. The results obtained from the electrical energy demand forecast is totally in the year 2016-2025 shows a positive trend that is increasing from 17.868 to 43.514 MWh. The average growth per year is 10,39%. With so large number growth in demand for electrical energy in the region of PT. PLN (Persero) Rayon Bangkinang, it is needed a new plant that will be able to fill the needs of electrical energy in the future. In kampar regency by 2015 there are 30.473 cows that can be used for biogas energy sources, the potential of electrical energy that can be utilized from cows dung processing into biogas energy is 21,273 MW

Rancang Bangun Perbaikan Faktor Daya Otomatis Berbasis Smart Relay pada Jaringan Tegangan Rendah Tiga Fasa

Power factor is one of the problems in the electric power quality improvement. Power factor value that is too low can result in some electrical equipment can not operate properly. In many ways, low power factor need not cost cheap. To assist in the use of power factor correction capacitor banks to provide reactive power in the system. To improve the power factor is low, then the study will be compensated automatically by using smart relay as a switch to the capacitor bank. Cosphi great start on system is 0,26 lag with the addition of 2,08-33 µF capacitor to cosphi be 0.99 Lag

Analisis Rancang Bangun Pembangkit Listrik dengan Mesin Sepeda Motor dengan Penggerak Mula Terkendali

Utilization of DC motors for moving the mechanical drive in place of the gas starter (prime mover). Which controlled by a controller to regulate the movement of the voltage controlled DC motor power window. Change of generator output voltage will read the sensor voltage Vout generator converted to a voltage which in this Vdc. Voltage read ATMEGA8 Mickrokontroler IC by using the ADC will determine the movement of the motor as the controller of gas, if the voltage is less than 220 V to its minimum voltage of the motor which has coupled on gas prime movers will rotate clockwise so the motor is pulling gas to reach the expected speed of the generator and its reverse in case of overspeed which causes more stress then the generator will rotate anti-clockwise so that the gas will drop to adjust the speed generator. So, rotation of DC motors forward and reverse and at a predetermined voltage level is normal voltage 220 -230 V motor will stop, and will hold the gas engine driving the generator speed will be maintained so long as the voltage under normal conditions 220-230 V.
