Abstract
Dalam Sebuah sistem tenaga yang sering terjadi saling
terinterkoneksi kondisi abnormal (seperti: overload, overvoltage,
overcurrent, dsb). Karenanya, gangguan pada sumber dan peralatan yang
terhubung sering terjadi kerusakan. Dalam hal ini, komponen yang
terkena gangguan harus segera diidentifikasi dan diisolasi untuk
menjamin supply terpenuhi dan menjaga stabilitas sistem, untuk itu
dibutuhkanlah proteksi yang handal. Disamping itu, dengan adanya
injeksi distributed generator, umumnya mempengaruhi sistem proteksi
yang ada pada sistem tenaga listrik. Kendala yang terjadi dalam
mengoordinasikan sistem proteksi yang handal terletak pada waktu
operasi yang sangat berdekatan antara rele primer yang ada pada suatu
bus dengan rele primer lainnya serta rele backup yang merupakan backup
dari rele primer tersebut. Plant IEEE dengan 8-Bus merupakan bentuk
jaringan distribusi mesh, dimana plant tersebut sangat sulit atau kompleks
untuk menetukan sistem proteksinya dibandingkan dengan jaringan
radial. Berdasarkan plant tersebut dibuat single line diagram sistem
distribusi mesh 8 bus, 14 rele arah arus lebih, 2 unit pembangkit, dan 1
pembangkit tersebar. Dari permasalahan tersebut diperlukanlah sebuah
penyelesaian yang optimal dan tepat. Hasil dari analisa, directional
overcurrent relay bekerja berdasarkan 2 kondisi yaitu forward dan
reverse, hal tersebut tergambar dalam penetuan rele utama dan rele
backup. Optimasi yang dilakukan dengan menggunakan genetic
algorithm mempunyai nilai total waktu operasi primer sebesar 9,3317
detik. Metode genetic algorithm dapat digunakan untuk menala parameter
rele arah arus lebih sehingga didapatkan koordinasi rele arah arus lebih
yang optimal.

In a power system that often occurs interconnected abnormal
conditions (such as: overload, overvoltage, overcurrent, etc.). Therefore,
interference with the source and connected equipment damage often
occurs. In this case, the components are exposed to disturbances must be
identified and isolated to ensure supply and maintain the stability of the
system is met, for it needed a reliable protection. In addition, with the
injection of distributed generators, generally affecting the existing system
of protection of the power system. Obstacles that occur in the coordinate
system lies in the reliable protection operation time is very close between
the primary relay is on a bus with other primary relay and relay back-up
which is a back-up of the primary relay. IEEE plant with 8-Bus is a form
of mesh distribution network, where the plant is very difficult or complex
to determine the system of protection compared with radial network. The
plant is based on the single line diagram made mesh distribution system
8 bus, 14 relay direction of overcurrent, 2 generating units, and 1
distributed generation. Of a solution to these problems requires the
optimal and appropriate. Results of the analysis, Directional overcurrent
relay work on two conditions, namely forward and reverse, it is reflected
in the determination of the main relay and relay backups. Optimization
by using a genetic algorithm has a total value of primary time operation
for 9,3317 seconds. Methods of genetic algorithm can be used to tune the
parameters overcurrent relay direction to obtain the coordination of
overcurrent relay optimal direction.
