Comparison of various alogrithms in different loading of load flow analysis / Nur Atikah Tajudin
Analisis aliran kuasa adalah tulang belakang analisis sistem kuasa dan reka bentuk. Mereka perlu untuk perancangan, operasi, penjadualan ekonomi dan pertukaran kuasa antara utiliti. Maklumat utama analisis aliran kuasa adalah untuk mencari sudut magnitud dan fasa voltan di setiap bas dan kuasa sebenar dan reaktif yang mengalir di setiap talian penghantaran. Analisis aliran kuasa adalah alat penting yang melibatkan analisis berangka yang digunakan untuk sistem kuasa. Dalam analisis ini, teknik berulang digunakan kerana tidak ada kaedah analisis untuk menyelesaikan masalah. Banyak algoritma yang digunakan untuk menyelesaikan masalah aliran kuasa dalam sistem kuasa tetapi algoritma utama yang selalu digunakan adalah kaedah Newton Raphson, kaedah Gauss Seidel dan kaedah Fast Decoupled. Tujuan projek ini adalah perbandingan pelbagai algoritma dalam memuatkan beban beban analisa aliran tenaga yang berbeza. Kaedah Newton Raphson, Kaedah Gauss Seidel dan Kaedah Fast Decoupled dalam analisis aliran beban untuk beban yang berbeza adalah pelaksanaan dalam projek ini menggunakan MATLAB R2017a. Set persamaan algebra bukan linear diselesaikan menggunakan kaedah lelaran. Hasilnya dibandingkan dengan bilangan lelaran dan masa pengiraan yang diambil. Kerja-kerja penyelidikan ini dilaksanakan menggunakan sistem IEEE 14-Bus, IEEE 30-Bus dan IEEE-57-Bus. _______________________________________________________________________________________________________ Power flow analysis is the backbone of power system analysis and design. They are necessary for planning, operation, economic scheduling and exchange of power between utilities. The principal information of power flow analysis is to find the magnitude and phase angle of voltage at each bus and the real and reactive power flowing in each transmission lines. Power flow analysis is an important tool involving numerical analysis applied to a power system. In this analysis, iterative techniques are used due to the unavailability of analytical method to solve the problem. Many algorithms are being used to solve the problem of power flow in power system but the main algorithms always used are Newton Raphson method, Gauss Seidel method and Fast Decoupled method. The aim of this project is the comparison of various algorithms in different load loading of power flow analysis. Newton Raphson method, Gauss Seidel method and Fast Decoupled method in load flow analysis for different loading are implementation in this project using MATLAB R2017a. The set of nonlinear algebraic equations is solved using iteration methods. The results ware compared for number of iteration and the computational time taken. This research work are implemented using IEEE 14-Bus, IEEE 30-Bus and IEEE 57-Bus system.
