Abstract
Therefore, the main objective of this thesis is to reduce disturbance so as to maintain the continuity of the operation of the reactor, in addition to that, to increase the life time of the reactor components and reduce the economic cost. It is well known that power quality is necessary for the system of the second Egyptian research reactor complex. The electrical disturbances of all kinds are considered the most important problems of power quality, which greatly affect the reactor’s devices and equipment’s, which necessitates improvement and mitigation of its effects. The good power quality helps to make the right decision in the inner Nuclear Research Reactor (NRR) facilities. Power quality Monitoring (PQM) and inspection is essential to maintain the ideal and safe operation of sensitive equipment especially nuclear installations.
In this thesis, a real case study of a nuclear side which contains four facilities, fed from two stations, was studied and readings were taken for long periods. The facility’s neighbors are classified as heavy industries and generate an electrical noise. The various power quality events such as voltage swell, voltage sag, impulsive transient, oscillatory transient, flickers, harmonics and interruption have been measured and analyzed to indicate the energy quality of the two feeders. This thesis is a step to assess the performance of the system and find solutions to reach safe normal operation of nuclear facility.
This thesis introduces a new vision of using Unified Power Flow Controller (UPFC) device that enhances and widens the range of controlling both active and reactive power flow, mitigates the voltage sag and swell and minimizing the total Power Loss (PL) and the harmonics with keeping the voltage in the specific limit. It also presents different UPFC controllers i.e. PI based UPFC. The Particle Swarm Optimization (PSO) approach was employed to solve the optimal UPFC allocation issue. The proposed strategy is tested on a genuine NRR using the Simulink MATLAB application and applied to the IEEE 33-bus test system. The results demonstrate that the technique is effective.
