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the reconducting of Tebing Tinggi - Kuala Tanjung transmission uses ACSR conductor types and after the reconducting has been replaced by the ACCC, where ACCC has 2 times the current trying of the type of ACSR.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%.

Power is the basic key for growth of any country’s economy. The increased demand of electricity, need to optimize the utilization of power generation capacity and increase in the interconnections are the major issues with which power sector is dealing with. Energy consumption per person is also rising tremendously in developing countries. However, installing a new power plant cannot be a solution every time. Dense population, availability of land, initial and installation cost can be the major issues in this case. Huge transfer of power from generating plants to load centre at long distance with bulky transmission lines is causing to upgrade voltage class to Extra High Voltage (EHV) from High Voltage (HV).

ABSTRAK Umumnya pada sistem tenaga listrik letak antara pusat pembangkit dengan pusat beban berjauhan. Tenaga listrik biasanya di butuhkan saluran transmisi yang cukup panjang untuk menyalurkan daya listrik ke pusat-pusat beban tersebut. Penelitian ini di lakukan dengan menggunakan Parameter ABCD saluran transmisi untuk menentukan tegangan, arus, faktor daya serta daya yang di kirim dari GI Bolok sampai ke GI Maulafa, GI Naibonat dan GI Nonohonis. Parameter ABCD adalah suatu rangkaian kutub empat yang dapat menggambarkan saluran transmisi karena memiliki dua terminal input dan dua terminal output. Jarak saluran transmisi dari GI Bolok ke GI Maulafa 14.5 kms menggunakan penghantar jenis ACSR HAWK 240 mm2, jarak dari GI Maulafa ke GI Naibonat 35.97 kms menggunakan penghantar ACSR OSTRICH 152 mm2, jarak dari GI Naibonat ke GI Nonohonis 62.29 kms menggunakan penghantar ACSR OSTRICH 152 mm2. Hasil dari penelitian ini, untuk Saluran Bolok –Maulafa VS 69.76 kV dengan VR 68.69 kV, IS dan IR 259 A, PfS dan PfR 0.9, PS 31.27 MW dengan PR 30.07 MW. Saluran Maulafa – Naibonat VS 68.98 kV dengan VR 67.52 kV, IS dan IR 121 A, PfS dan PfR 0.9, PS 14.44 MW dengan PR 14.10 MW. Saluran Naibonat – Nonohonis VS 67.27 kV dengan VR 65.10 kV, IS dan IR 104 A PfS dan PfR 0.9, PS 12.09 MW dengan PR 11.70 MW. Saluran Bolok – Maulafa rugi-rugi daya tiap saluran sebesar 1.11 MW, regulasi tegangan 1.27 % dengan effisiensi saluran 98.14 %. Saluran Maulafa – Naibonat rugi-rugi daya sebesar 0.59 MW, regulasi tegangan 2.16 % dan effisiensi saluran 97.45 %. Saluran Naibonat – Nonohonis rugi-rugi daya sebesar 0.69 MW, regulasi tegangan 3.34 %, dan effisiensi saluran 96.38 %. Dari hasil perhitungan diatas menunjukan bahwa jatuh tegangan berada pada kondisi yang stabil berdasarkan aturan SPLN 1 1978.   ABSTRACT Generally in the electric power system, the location between the power plant and the load center is far apart. Electric power usually need transmission line that has long enough line to deliver electrical power to the load centers. This research was using the ABCD Parameters to determine the voltage, current, power factor and power sent from the Bolok Substation to the Maulafa Substation, Naibonat Substation and Nonohonis Substation. The ABCD Parameter is a series of four poles that can describe the transmission line since it has two input ports and two output ports. The distance of the transmission line from Bolok Substation to Maulafa Substation is 14.5 kms using ACSR HAWK type 240 mm2, distance from Maulafa Substation to Naibonat Substation 35.97 kms using ACSR OSTRICH 152 mm2, distance from Naibonat Substation to Nonohonis Substation 62.29 kms using ACSR OSTRICH 152 mm2 152 mm2. The results of this study are Bolok – Maulafa line VS 69.76 kV with VR 68.69 kV, IS and IR  259 A, PfS  and PfR  0.9, PS  31.27 MW with PR  30.07 MW. Maulafa – Naibonat line VS 68.98 kV with VR 67.52 kV, IS and IR 121 A, PfS and PfR 0.9, PS 14.44 MW with PR 14.10 MW. Naibonat – Nonohonis line VS 67.27 kV with VR 65.10 kV, IS and IR 104 A, PfS and PfR 0.9, PS  12.09 MW with PR  11.70 MW. Bolok – Maulafa line the power losses in each line  are 1.11 MW, voltage regulation is 1.27%, with line efficiency is 98.14%. Maulafa - Naibonat line, the power losses of 0.59 MW, voltage regulation is 2.16%, with line efficiency of 97.45%. Naibonat - Nonohonis line, the power losses of 0.69 MW, voltage regulation is 3.34%, with line efficiency is 96.38%. The above calculation results show that the drop voltage is in a stable state based on the rule SPLN 1 1978.

In order to balance reactive power, reduce line losses, prevent excessive power frequency and switching over-voltage and adjust and control the line voltage etc. The long-distance and high voltage transmission lines are needed reactive power compensation. High voltage overhead transmission lines and high voltage submarine cable (including mixed-submarine) transmission lines are different, for example, the capacitance in the submarine cable lines is larger than in the conventional overhead lines. Therefore, the reactive power compensation on the EHV transmission lines which contains submarine cable lines is focus on the compensation of submarine cable lines. The reactive power compensation in 500 kV AC submarine cable interconnection project for Hainan power grid and Guangdong power grid[1], which is the first 500 kV long-distance and high-capacity sea trails interconnection project in China and which is just completed soon, is researched by Electro-Magnetic Transient Program——PSCAD/EMTDC (Power System Computer Aided Design/ Electro Magnetic Transient in DC System in this paper). The simulation results verifies that the role of shunt reactor which could absorb charging power and suppress the power frequency overvoltage for the long-distance and high-capacity hybrid submarine cable lines. The conclusions can offer references to suppress power frequency overvoltage and the reactive power compensation in extra high voltage transmission lines which is the mixed mode of overhead transmission lines and submarine cables.
