- 摘要：The unified power quality conditioner (UPQC) is predominantly designed and implemented by
utilizing the voltage source converter (VSC) topology with proportional - integral (PI), Fuzzy
logic and Artificial Neural Network (ANN) based controllers, etc. for mitigating electric power
quality (PQ) problems in distribution systems. The availability of very few literature on the
application of current source converter (CSC) topology in custom power device (CPD) suggests
that there are still significant research scopes in this area. This paper proposes a right shunt
configured UPQC model based on the much overlooked CSC topology. The proposed model is
controlled by two simple controllers viz. PI and Hysteresis band controllers acting in a
coordinated manner eliminating the interference between the shunt converter and passive filter,
requirement of the pre-charged capacitor on the DC link section and works with greater
reliability, fault-tolerant, and efficiency. The performance assessment of the proposed model has
been carried out through simulation with the help of Matlab©-Simulink. The results of the
simulation study reveal that the proposed model can alleviate both the problems of voltage sag
and harmonics simultaneously in a secondary power distribution system feeding a nonlinear
load thereby improving power quality to the levels prescribed by the IEEE Standards.
