Abstract

Recently distribution network have connected with power plant unit also with photovoltaic power plant. Therefore voltage profile of distribution grid not any more distance from source there is voltage drop but connected with photovoltaic power plant would be increase grid voltage in this connected point also in the grid line. In this study, the distribution grid with connected with photovoltaic power plant is modelled. By using through MATHLAB / SIMULINK,  modeling and simulation can be done ondistribution grid with two point connected to the photovoltaic power plant.   From the simulation and analysis obtained, that power injection to grid by photovoltaic power plant can affect voltage grid condition, but not affect grid frequency relatively. The grid voltage will increase if there is power injection to the connected point in grid. Increase the power penetration to the grid would be increase the rise voltage in the grid. The constraint in this case, that power   penetration must be considered the condition of quality voltage because any trend for voltage wave become distorted.

Abstract

With the growth of electricity consumption getting bigger, the possibility of greater losses arises from measuring energy in customers. One cause of the losses due to mistakes in flow ratio CT (Current Transformer) installed on APP Box indirect measurement. Necessary to test the CT accuracy class to determine the current ratio error limits set by the standard PLN. Then do the replacement on the CT accuracy class to resolve this issue. This activity is done at the customer PT. Astra Int Auto 2000 by replacing the CT accuracy class of 0.5 becomes 0,5S. There is a comparison of the measurement between the two different classes. Based on the results of tests performed, a decline in the current ratio error before and after the replacement of accuracy class. After calculating the error margin of the second flow ratio CT installed that are not measured by the energy meter. This Value kWh that is the losses to PT. PLN (Persero) Area Depok. So understanding CT as one of the tools of measurement (instrumentation) should be changed to a point of transaction (point of transaction). So that the revenue gains kWh a business orientation that is fundamental to PLN by pressing slightly possible energy losses (losses) that occur in the measurement system.

Abstract

Entering the 21st century, oil and gas supplies are running low. While the need for energy is increasing, especially in industrialized countries, it will increase to 70% between 2000 and 2030. In 2017, the electricity needs will reach 25.4 trillion kWh. Solar energy that can be generated for the entire Indonesian mainland which has an area of ​​± 2 million km2 with a radiation distribution of 4.8 kWh/m2/day is 5.10 mW, equivalent to 112,000 gWp. In terms of technique in totality it can be said that it is feasible to operate, solar panels have an efficiency increase of 17.4%. In terms of components and regional quality that will be absorbed by PLTS and synchronized by KWH EXIM, from calculations with a performance ratio yielding 81%, so the system is technically said to be feasible to be realized.

Abstract

Beside transportation sector, industrial sector is one of the biggest energy consumption sector.Therefore, any energy conservation effort in this sector will contribute to the energy demand reduction as targeted in the National Energy Policy (KEN) and National Energy Plan (RUEN). This study tries to estimate the potential of energy conservation in Industrial sector by implementing four energy conservation policies, mamely: 1) implementation of energy management system, 2) boiler efficiency improvement, 3) Minimum Energy Performance Standards (MEPS) implementation for  electric motor, and 4) MEPS implementation for chillers. Potential of energy conservation was calculated by using Long Range Energy Alternative Planning (LEAP) software. The results of this study indicate that the implemntation of those energy conservation policies has the potential to reduce energy demands by 35 million Barrel Oil Equivalent (BOE) or by 7.9%  in 2025 and 232 million BOE or 15.3% in 2050 as compared to energy demand in the Business as Usual (BAU) scenario. In sthe hort-term, (2025), the contribution of  energy saving  from the implementation  of : energy management  system, improving boiler efficiency, implementation of MEPS for electric motors, and implementation of MEPS for chillers are 1.1%, 6.3%, 0.5%, and 0% , respectivily. While, for the  long -term (2050) , the contribution of each policy are 6.5%, 6%,2.2%, and 0.5%, respectively.Beside transportation sector, industrial sector is one of the biggest energy consumption sector.Therefore, any energy conservation effort in this sector will contribute to the energy demand reduction as targeted in the National Energy Policy (KEN) and National Energy Plan (RUEN).

Abstract

Electricity need in Indonesia continues to increase in accordance with the rate of recovery of the economy and industry and the increase in population. The transmission line transmits electricity from the power plant to the load center via the High Voltage transmission lines (SUTT) or Extra High Voltage Transmissio lines (SUTET), because the long distance causes power losses. The condition before the reconducting of Tebing Tinggi - Kuala Tanjung transmission uses ACSR conductor types and after the reconducting has been replaced by the ACCC, where ACCC has 2 times the current trying of the type of ACSR. In this study, we will examine and analyze the magnitude of the power losses and the efficiency of the distribution of the two types of ACSR and ACCC supply channels with a case study of the 150 kV transmission system Tebing Tinggi - Kuala Tanjung which has a distance of 71.5 km. From the calculation results obtained, after the reconducting process using the conductor the ACCC was able to reduce power losses and increase efficiency by 1.35%.
