Abstract
This thesis presents analysis method of optimum power system planning. The Gauss-Seidel iteration method is used to calculate load flow data of power system. The real and reactive powers, voltage magnitude and phase angle at each bus were obtained using Gauss-Seidel iteration method for a given IEEE sample power system. The load flow calculations were repeated under 60 percentage, 70 percentage, 80 percentage, 90 percentage, 100 percentage loading condition.
The transformation of reference frames were performed to simplify given IEEE sample power system identification. The transformation of reference frame transforms real and reactive voltage, current and impedance variables(reference frame 1) into real power and real loss variables(power flow reference frame). The transformation of power flow reference frame provides great reduction of computational procedures which relate to data and time.
Based on load flow data and power flow reference frame, the optimum transmission loss coefficient matrix [B] and matrix function of load flow calculation parameter matrix [K] were calculated by using formulas which obtained in the mathematical procedures.
These matrices [B] and [K] were used to calculate the symmetrical resistance matrix [R] which represents new path to design power system in the power flow reference frame. Thete matrices [B], [K] and [R] were calculated under 60 percentage, 70 percentage, 80 percentage, 90 percentage, 100 percentage loading condition.
Optimum and economic operation of power system can be identified by inspection of the symmetrical resistance matrix [R].
