A New Effjcient Method for Load-Flow Solution for Radial Distribution Networks

摘要

A new efficient method is proposed for load-flow solution of radial distribution networks. Simple transcendental equations are used to relate the sending-end voltage, receiving-end voltage and voltage drops in each branch of the distribution system. The effect of charging capacitance of the line has been incorporated in load-flow solution. A computer algorithm is developed in such a way that there is no need to adopt any sequential node numbering scheme for the solution of the networks. The angle of the receiving-end voltage is also computed along with the magnitude of the voltage. It is an iterative method. The flat voltage (1pu) start from substation to every end-node is considered. The voltage magnitude and angle are updated after each successive iteration and the voltage drops are then computed by using the new obtained values of voltage magnitude and angle. The comparison of speed and memory requirement by the proposed method with the other methods has been verified to show its efficiency.%Zapropowano nową metodę kontroli przepływu mocy w radialnej sieci rozproszonej. Użyto prostego równania transcedentalnego do opisu napięcia wysyłanego, otrzymanego I spadki napięcia w każdej z gałęzi sieci. Opracowano odpowiedni algorytm komputerowy a obliczenia są przeprowadzane iteracyjne, gdzie amplituda I kąt napięcia są sukcesywnie zmieniane.
