Abstract

Electrical energy generated also comes from several energy, namely water, steam, nuclear, etc. In Indonesia the type ofsteam power plant is a type of power plant that is widely used, where one of the crucial problems that are often encountered in this generation system, namely the problem of stability. The stability of the electric power system is the ability of the system to return to normal or steady operation after a large load load switching or interference. Disruption or load switching that exist in the system must be muted and aligned in a certain time to be said to be stable. Causes of instability are disruptions in the form of large capacity load switching, and the type of interference. One aspect that affects the stability itself is the transient stability. The transient stability is related to the sudden influx of large-capacity loads and affect the performance of the generator, therefore it is necessary to analyze the voltage and frequency transient stability for the evaluation of the capability of the electrical system so that the system maintains the continuity of the supply of electrical energy to the load normally. Based on the research results, the current flowing before the disturbance of 98.9 A and current disturbance of 145.2 kA. This causes the voltage response to decrease 50% of the nominal, and the frequency increases to 50.36 Hz. The time required from the disturbance condition to a stable condition within 5 seconds.

Abstract

The unbalanced load on distribution transformers is mostly caused of connecting new customers and changing patterns of electricity usage in the community. The impact of the unbalanced load is the emergence of a current flowing on the transformer neutral conductor that causes energy losses. Load balancing of distribution transformers is commonly done by technicians, but the implementation takes quite a long time and is repeated, sometimes up to 4-5 times to get the appropriate results. This is more due to less valid customer phase data. Customer phase verification is needed to accelerate the load balancing process in an effort to reduce losses in distribution transformers. With valid customer phase data, just one stage of load balancing can reduce losses by 1.06 persen.

Abstract

Penyeimbangan beban dilakukan untuk mengurangi losses (rugi-rugi) pada trafo distribusi, dan verifikasi phasa pelanggan dengan pendeteksian phasa menjadi kunci keberhasilan pada prosesnya. Metode pembacaan phasa dilakukan dengan menghitung selisih waktu antara perpotongan gelombang dengan titik nol dari suatu phasa kemudian membandingkan dengan phasa yang lain. Pendeteksian phasa pelanggan membutuhkan peralatan dengan sensor phasa yang tepat dan akurat yaitu dengan menggunakan metode Positive Edge Comparation, Arduino dan Transciever LoRa. Hasil pengambilan data dengan pengujian pada laboratorium menunjukkan bahwa toleransi beda phasa dengan simpangan maksimum sebesar ± 18⁰ dan jarak terjauh untuk mendapatkan data phasa yang tepat adalah 50m pada posisi Line of Sight. semakin jauh jarak pendeteksian maka simpangan sudut phasa semakin besar.

Abstract

The installation of lighting and running text in the housing gate is expected to provide lighting around the gate so that it is clearly seen if there are vehicles passing by. In addition, with the upgrade of the information board using an electronic board (running text) it becomes very clear and beautiful both in the morning and at night.
