1.Membuat Aplikasi MATLAB GUI Dari hasil Load Flow. Data yang digunakan adalah data IEEE 30 Bus System (terlampir) Menentukan beberapa 3 buah skenario pembebanan Contoh scenario(bebas) Scenario 1 : beban MW di bus 1,2 dan 3 dinaikkan, contoh bus 1 30 MW, bus 2 30 MW bus

3 40 MW

Scenario 2 : beban MW di bus 29 dan 30 dinaikkan, contoh bus29 50 MW, bus 30 30 MW Scenario 3 : beban MW di bus 15 dan 17 dinaikkan, contoh bus 15 40 MW dan bus 17 40

MW

Hasil yang ditampilkan di MATLAB GUIo 7 Bus dengan tegangan terendah dan juga nilai tegangannyao 7 Line dengan nilai arus terbesar dan juga nilai arusnyao Hasil yang ditampilkan di GUI dilakukan untuk setiap skenario

Membuat deskripsi dari ketiga scenario yang telah dibuat dan juga membuat deskripsitentang hasil yang tertampil di GUI

Tanpa Skenario

Hasil simulasi di atas murni menggunakan data dari IEEE 30 Bus. Dari hasil load flow analysis

ditampilkan 7 bus dengan tegangan terendah dan juga 7 branch antarbus dengan kuat arus

terbesar. Arus terbesar pada sistem terletak di antara bus1 dengan bus2 karena bus1 dan bus2merupakan bus reference dan salah satu bus generator.

Skenario 1

Pada skenario ini, beban pada bus1, bus2, dan bus3 dinaikkan menjadi:1. Bus 01 = 30 MW2. Bus 02 = 30 MW3. Bus 03 = 40 MW

Dengan naiknya beban di bus-bus tersebut, maka menyebabkan tegangan ujung bus yangdibawah 1 pu bertambah, yaitu sejumlah 3 bus. Arus terbesar pada sistem terletak di antara bus1

dengan bus2 dengan magnitude mendekati 2pu karena MW beban pada bus1 dan bus2 juga

sangat besar, yaitu sebesar 50MW.


4/23



Skenario 2

Pada skenario ini, pembebanan pada bus29 dan bus30 dinaikkan menjadi:1. Bus 29 = 20 MW2. Bus 30 = 20 MWBus29 dan Bus30 masing masing terhubung langsung dengan bus27 yang mana merupakan bus

generator. Dengan adanya pembebanan yang cukup besar di dekat sumber tenaga, menyebabkan

tegangan pada ujung-ujung bus lainnya menjadi mengecil. Tegangan yang kecil menunujukkan

kondisi bus yang paling kritis.


5/23



Skenario 3

Pada skenario ini, pembebanan pada bus15 dan bus17 dinaikkan menjadi:1. Bus 15 = 40 MW2. Bus 17 = 40 MWPada kondisi ini, besar arus di tiga branch sistem sangat besar di atas 1pu. Ini disebabkan karena

pembebanan yang mendadak tinggi di sisi tengah sistem. Sebelumnya, pada bus 15 dan bus 17

hanya dibebani dibawah 10 MW, namun dengan adanya penambahan beban ke nominal 4 kali

lipatnya dapat menyebabkan naiknya arus pada sistem dan juga semakin banyak bus yangtegangannya kritis.

Source Code GUIfunction varargout = mid2(varargin)% MID2 MATLAB code for mid2.fig% MID2, by itself, creates a new MID2 or raises the existing% singleton*.

%% H = MID2 returns the handle to a new MID2 or the handle to% the existing singleton*.%% MID2('CALLBACK',hObject,eventData,handles,...) calls the local% function named CALLBACK in MID2.M with the given input arguments.%% MID2('Property','Value',...) creates a new MID2 or raises the% existing singleton*.

2.Menghitung Nilai Hubung Singkat tiga Fase ke TanahData yang digunakan adalah data IEEE 30 Bus System.

Digunakan 3 skenario Hubung Singkat, antara lain:

Skenario 1 : Hubung Singkat di Bus 07 dengan Zf = 0.01 + j0.02 puSkenario 2 : Hubung Singkat di Bus 13 dengan Zf = 0.03 puSkenario 3 : Hubung Singkat di Bus 21 dengan Zf = 0.04 + j 0.3 pu

Digunakan 2 buah asumsi untuk menghitung hubung singkat.

Nilai Tegangan Awal Semua Bus 1 pu dan line charging diabaikanNilai Tegangan Awal Semua Bus dihitung dengan Load Flow

Skenario 1 Hubung Singkat terjadi di Bus 07, yang merupakan bus beban dengan beban sebesar

22.8MW 10.9MVAr

Tegangan pada bus 13 tempat hubung singkat terjadi sebesar 0.212 p.u. Besar teganganini mendekati nol namun tidak sampai bernilai 0 karena walaupun terjadi hubung singkat

masih terdapat impedansi pada antar fase-nya.
