الملخص الإنجليزي

Distribution loud how is a very important and basic tool lord the analysis of distribution systems.

Many applications in the distribution system needs the support of robust and efficient power How algorithm, and such algorithm must be able to model the special features of the distribution system.

In this work, distribution system load flow analysis is formulated and tested lord ruiidamenta! Steady-state and harmonics power how.

For the steady-state analysis, a novel power how formulation method for the general multiphase balanced and / or unbalanced radial distribution systems is presented.

Different system components are modeled and easily addressed in the data.

The special topology of the power distribution system has been fully exploited to facilitate obtaining a direct solution using the graph theory.

Only one developed matrix used in conjunction with simple standard formulation is enough to obtain the power flow solution.

This matrix is the branch-path incLde.nl matrix.

A feature of using this method is that it significantly reduces the number of power how equations, as compared to conventional methods, hence very low computation time and memory storage.

The presence of nonlinear loads in the power system causes the circulation of harmonics currents in the system, leading to harmonics voltage drops.

The harmonics how analysis in this work, uses the network techniques in conjunction with graph theory resulting in a powerful algorithm for nonlinear load flow analysis.

Six pulse converters model were used to represent the nonlinear load.

Two universal programs written in MATLAB have been built and used to solve for the load (low solution of standard test systems in both steady-state and harmonics cases.

The results of the distribution system cases studies are presented and shows a very good resemblance with a standard results.
