ANALISA RUGI-RUGI DAYA DAN JATUH TEGANGAN PADA SALURAN DISTRIBUSI TEGANGAN MENENGAH 20 KV GARDU INDUK TALANG KELAPA PALEMBANG
Daftar Isi:
- To produce electricity which can be consumed by customer as load, the process of distributing electricity by PLN will be proceed through several stages such as conversion of energy and distribution. The distribution process is started from substation, to the districts then finally to the load center. As in Talang Kelapa Substation, located in Jalan Diponegoro Dusun II, Sukomoro, Banyuasin which owns one feeder named Penyulang Srikandi, which distributes 20 KV of electricity with 147 channel lengths, 9745 km with 120 distribution transformers, so that calculations and analysis are needed with the aim of knowing the value of power losses and voltage drop and comparing the value of the calculation results to the tolerance limits that are commonly applied to the SUTM distribution system. By using the calculation method through the formula of falling voltage and power losses which results in the calculation that the length of flow and the amount of load connected with Srikandi Feeder causes Srikandi Feeder to have a voltage drop value that exceeds the tolerance limit of PLN as a standard in the distribution of electricity equal to 11.4871 %V or ∆V 2.271 Volt. Because of the voltage drop, there will be power losses. Power losses that are directly proportional to the load current and channel length cause power losses in Srikandi Feeder to reach 9.7980 %Ploss or Ploss 245,6905 KWatt. However, if the tolerance limit of + 5% and -10% from PLN becomes a standard, for power losses in Srikandi Feeder, still within the limits of its tolerance standards even though it has entered a critical boundary. Keywords: Distribution, power losses, voltage drop.
