Wonderful Life (part 2)

The question is : HOW IT CAN BE SOLVED (pararelly)???

Of course priorities and clear understanding about the problem are needed in here, BUT friends is the most needed one :D.

So, I contacted all of my relatives and here is the result :

1. Reliability design of Kulon Progo Airport : solved with the help from Pak Nengah (protection and reliability guru in EE UGM; glad to have his guidance J )
2. Electricity roadmap DIY : helped by 2011 student (thanks Titis :D )
3. Electricity policy DIY : also helped by 2011 student  (thanks Fachri :D )

So it leave me to the papers; workshop; and interview. The papers is the most priorities in here due to the ICITEE event held in UGM. But doing 3 papers pararelly is just a suicidal mission. None of them are completed :v.

Here is the percentage completion of the papers in June 24^th (the due date of submission) :

1. Impact of Neutral Wire Absence in KBL-5 and KBL-6 : 90% completed --> would be submitted to another event
2. Modal Optimal Control for UPFC using PSO : 100% (sadly, it was not accepted by my supervisor because it is similiar with the last paper, T.T)
3. FACTS controlling using Genetic Algorithm : 70% (can’t be completed because suddenly my supervisor told me to change the paper’s theme, -.- )

Well, I think that the papers stuff is a litte (very) boring to you, so let’s move to the cool part.

It was  June 28^th friday afternoon when my uncle said that he would pick me up at 5 to see Ramayana Ballet. I am still doing the reability design and looks like that it was impossible. I contacted Nizar to help me made the presentation and it was still impossible to finish it before 5 (the progress is about 90%).  So here is the thing that I do : I create the key point and Nizar made the sentence, and not only that, he also sent the presentation in behalf of me using my email. 

Saya yakin cm saya yg ndak mandi + sandal jepitan pas nonton ramayana ballet :v 

By the way, I recommend you to see Ramayana Ballet, the stage is great, the lighting is awesome, the ballet is majestic, certainly worth every penny J

So, what's next? The IPA workshop and interview :D

The interview is held in Monday in Cikarang KKO building at 10.00 AM, it was too risky going there in Sunday (traffic jam and fatigue issue) and I'm not too crazy to let go the chance attending IPA workshop.
To add the gregetness (wtf :p) of the situation : all train and busses are full booked for saturday night and sunday morning. I also haven’t prepared  for the interview clothes. Pak Sarjiya also ask me to revise the small part of the presentation. HAHAHAHA.

So here is the solution : I am absent from the first IPA session, editing the PPT,  buying some clothes and preparing the things, then attend the 2^nd session at 01.20 (late for 20 minutes), and at 5 taking the travel to Depok (thank God, there is still available travel). Btw you won’t believe that eventhough I dont attend studium generale and late for the 2^nd session, I was still selected to represent my group to present the result of discussion in front of IPA delegation and a total of 250 participant :v. A chance hard to resist, but logic must takes its role. Politely refuse the chance because travel came at 5.

When I realized  all the things that i've done;  my feeling was like :

THAT FEELING IS AWESOME!!!

Wonderful Life (part 1)

The story itself began at June 26^th. I was in the middle of doing some, well let’s say : a project; when my phone ringing suddenly. The voice in the spoke calmly yet very clearly: “Rian we schedule you an interview for wireline user in Monday at Cilandak KKO Building.” Oookay, at first I was like jumping for joy; but wait, monday? 

The very moment before my phone rang, I was browsing internet and looks like I was accepted as participant of IPA (Indonesian Petroleum Ascossiation) in the next saturday.

One day before that, I was asked to make a presentation about reliability design for the new airport in Kulon Progo, and the due date is 27^th_.

3 days before that, I was asked to make academic draft report for electricity policy in DIY.

And one week before that I was asked to make electricity roadmap planning for DIY 2013 – 2017.

Dont you think it's over, in that week (it means one week before the phone rang) my lecturer asked to write some  papers (YES, some papers not just a paper but 3 papers) :D

The sum up of all my feeling right now is this meme :

Well, okay Sir....

What a wonderful life I have :) #breathe deeply

Studi hilangnya kawat netral (1)

Apa yang terlintas di bayangan teman2 sekalian kalo dengar kata “kawat netral”. Kalo ditanya ke anak elektro pasti pada jawab buat ngalirin arus netral. Ya, tepat sekali, kawat netral bisa berfungsi buat ngalirin arus netral (bagi yang belum tahu apa itu kawat netral, itu lho kawat yang biasanya di taruh paling bawah disambungan tiang2 listrik, dan ukurannya lebih kecil dibanding yang lain). Nah, kebetulan kami (saya+rovi+fahmi+arip) mbantu2 dosen buat ngerjain proyek tentang kawat netral. 

Nama keren proyeknya si, “Studi Pengaruh Hilangnya Kawat Netral Terhadap Kerja Pengaman Arus Lebih Jaringan Distribusi Tegangan Menengah dan Ketidakimbangan Beban Terhadap Losses dan Drop Tegangan Wilayah Jawa Tengah dan DIY” (Panjangnyaaaaaaaaaaa). Nah kita tahu kan, kalo setting rele pengaman itu di set dengan kondisi optimal (maksudnya sesuai sama sldnya perencanaan jaringannya) sementara banyak kawat netral di Jateng – DIY yang hilang di curi @_@.  Disini selain kwat netral yang ilang juga di analisa pengaruh Zn (impedans pentanahan) terhadap  arus sama tegangan hubung singkat. Klo buat arusnya si mungkin sederhananya gini,misal setting rele pengamannya 100A, ternyata gara2 kawat netral nya hilang arus short circuitnya jadi lebih kecil sehingga rele pengamannya ga mendeteksi.  Bahaya kan, ada gangguan tapi peralatan pengamannya ga mendeteksi :D. Tegangan hubung singkatnya juga jangan di remehin, itu juga penting lho, hehehe. Tegangan hubung singkatnya dipakai buat nentuin apakah arrester nya masih sesui ga sama si tegangan SLG nya, klo ternyata tegangannya > BIL si arrester ya sama aja boong :D. Oiya, gangguan yang di simulasikan adalah single line to ground (SLG), pertimbangannya sih SLG merupakan gangguan yang paling sering terjadi di sistem distribusi :D

Hm hm hm, lantas klo drop tegangan sama losses daya apa ya yang di analisis? Nah, kalo buat tegangan, itu diliat pengaruh ketidak imbangan beban terhadap tegangan fasanya, klo ada kawat netral kan tegangan ga imbangnya ga terlalu signifikan (masi bisa di tolong sama kawat netra), nah kalo ga ada? Tentunya bakal semakin acak adut tegangan fasanya, fasornya semakin menggila karena referensi nya geser, ujung2nya pelanggan yang kasian, ada yang dapat tegangan nya kecil, tapi ada yang dapat overvoltage, wkwkwk. 

Klo losses daya kaitannya dengan arus netralnya, mudahnya semakin tidak imbang beban semakin besar arus netral yang ngalir, nah losses daya kan rumusnya I^R, ada losses fasa ada losses netral, semua tumplek blek, wkwkwk

oiya, sampai lupa, wilayah survei nya : Purwokerto, Purworejo, Klaten, Yogya, sama Solo. Lmyn jalan2 gratis :D
