Abstract
In this thesis, two proposed strategies are developed and applied to deal with recloser-fuse miscoordination problem in radial distribution systems using microprocessor-based recloser and control scheme. This miscoordination problem arises from the penetration of distributed generation (DG) in radial distribution systems. The proposed strategies include offline and adaptive online solutions, and are tested by simulating an actual system and a hardware implementation. A control scheme is applied to calculate the suitable setting of the fast mode recloser characteristic. The offline solution is applied in different case studies. Firstly, the size and location of DG are determined to calculate the maximum fault current of DG at this location. Then, the suitable setting for each location of DG is calculated. Thus, the control unit is used as a mediator to send the suitable setting to the recloser after receiving the status of connecting DG (on/off). Besides, the adaptive online solution is developed to determine the suitable setting of recloser for any number of DGs. The control unit communicates with the recloser and all DGs to determine the suitable setting for each case. Hardware implementation is also developed to evaluate the proposed strategies performance for both offline and online studies. It is concluded that the proposed strategies have high efficiency to deal with the miscoordination problem
