Abstract

rom EEOR, Electro Enhanced Oil Recovery, and a developing technology application which has been established earlier. The difference is ESOR relatively does not improve recovery factor of producing well. Ideally any crude oil producing well will be experiencing pressure decline which may affect crude oil production decrement, naturally. Regarding some similar researches around the world, the use of direct current electrical exposure was proven to increase number of heavy crude oil production. At least salinity, hydrocarbon chemical compounds and crude oil flow in the reservoir (electro-osmosis) involves during chemical processes in the reservoir while ESOR application. Number of electrons conducted from direct current electrical power supply will be a supporting media during chemical process of these parameters. Unfortunately after completing ESOR application in Lapangan X, the result was contradictive with this research hypothesis. Exposure of direct current electrical supply did not increased heavy crude oil production. On a contrary, parameter of salinity and API gravity as produced heavy crude oil quality, were improving significantly.

Abstract

Solar power plants (PLTS) as power plants that use solar rays to generate electrical energy have a big role in reducing the burden of reducing CO2 emissions. Electrical energy generated by solar panels in the form of direct current (DC / direct current) low voltage. This electrical energy will be collected and stored in a battery (accumulator / battery) through a battery charging controller or so-called solar charge controller that serves as a controller charging process so that the voltage and current are filled to the battery does not exceed the ability batteries or overcharge. This research will make the model of charging the batteries in the Solar Charger Controler by using Mamdani's fuzzy inference logic which is used to adjust the direct current that is charged to the battery and transmitted to the load on the PLTS system. This simulation is expected to be applied to a device that acts as a set of excess filling that is streamed from the solar panel to a fuzzy-based battery. Solar Charger based Fuzzy logic controller can be applied to automatically stop the activity if the voltage in the battery by adjusting the charging function and exemption of current from battery to load.

Abstract

Generally, The power centers are connected to the air transmission line, and the airborne transmission channel is susceptible to disturbances that are affected from outside the system, one of which is a lightning strike. Lightning strikes are harmful to the components present in the central power supply. And therefore, the protection from the lightning strikes is required, so that the components in the power center is not damaged when exposed to lightning surges. In this research we discussed the power transformer protection (60MVA) on the Teluk Betung substation so that the power transformer is safe from the over voltage caused by the lightning surge. The specification of the arresters mounted on the HV side of the power transformer unit one of Teluk Betung substation with nominal voltage of 144 kV has been in accordance with the system requirements. The maximum distance between the arrester and the allowable power transformer is 28.5 meters. Distance in the field is 3 meters, the voltage that arrives at the power transformer is 480 kV and still below the Basic insulation level of the transformer, so that the protection of the power transformer against the lightning surge is very good.

Abstract

Solar Street Lighting Light (PJU-TS) is a street lighting that uses sunlight as a source of electrical energy. The Solar Street Lighting (PJU-TS) is suitable for roads in areas not covered by PLN electricity and also areas experiencing electrical energy crisis especially in remote areas. But recently PJU Solar is also rife applied in urban areas such as in the main streets, residential street, garden lights, campus area, factory area, bus stops, parking lots, gas stations (gas stations) and so on. In the process of making solar lighting control system on the lamp for PJU is first to determine the load installed, then calculate the number of solar panels or photovoltaic needs, then calculate the battery requirements and determine the capacity of the battery charge regulator (BCR). Then for PJU lamps to operate automatically installed light sensor or light dependent resistor (LDR) as a switch to turn on and off PJU lights.
