Performance comparison of electric power flow solutions using PSCAD

摘要

This paper presents the analysis of electric power flow solution consists of specified power and voltage input conditions to power network and producing the complete voltage information at all the system busses. From this analysis the parameters of current flow and voltages were obtained. Computation of power flow solution is easy if it does not involve with a large power system. But, if a power system is involved with hundred or thousand buses it is complicated to calculate using calculator or iteration method. The Power System Computer Aided Design (PSCAD) software was chosen to solve the problem of power flow solution. There are many software programs such as Matlab, PSCAD and PSpice but PSCAD was chosen to solve power flow solution. It was because PSCAD is the best simulation method and provided quick and economic results with high accuracy. Computer simulation was used extensively in the power flow study because of the large scale nature of the problem and the complexity involved. The main purpose of this project was to solve power flow solution system by using PSCAD, hence developed the power flow model by using PSCAD. This model was used to analyze and observes the project result based on theoretical and simulation method. The result of performance shown for this project was successful depends on simulation using PSCAD software. It was easier to analyze complicated power flow solution by using PSCAD.
