TY - JOUR ID - TI - POWER FACTOR CORRECTION IN A RADIAL DISTRIBUTION SYSTEM USING OPTIMAL CAPACITOR PLACEMENT FOR BAGHDAD CITY AU - Nidaa Hameed Dawod PY - 2019 VL - 23 IS - 4 SP - 100 EP - 118 JO - Journal of Engineering and Sustainable Development (JEASD) مجلة الهندسة والتنمية المستدامة SN - 25200917 25200925 AB - In recent years the nature of load has changed drastically and different electrical equipment's. mercury lamps, transformers, motors, switchgears are running inherently at low power factor. Planning of electrical distribution networks is considered of highest priority at the present time in Baghdad city, due to the huge increase in electrical power demand and expansions imposed on distribution networks as a result of the great and rapid urban - development. This work presents the new and efficient approach for capacitor placement in radial distribution network that determine the optimal locations and size of capacitor with the main objective for the improving voltage profile, reducing active power losses and improving power factor. This work includes two parts: part one implementation on the IEEE 33-bus test system using CYMDIST software program, as a tool for the simulation of a distribution network and performing the required analysis. The results, shows a good matching as compared with previous work mentioned in the literature and used for the same network but the analysis of different ways. , and in part two, we select actual sector of Baghdad city distribution network that is Al Adel_33/11kV_feeders 2, 3, 6, and 7 (11 kV_93 bus) network is depicted for the implementation of this analysis. The results using backward / forward load flow method, show that minimum power losses and improving voltage profile had been achieved. So the network can be operate in normal condition without any violating operational constraints.
