Control of Shunt Active Power Conditioner Using Instantaneous Reactive Power Technique

Yashvant Singh, Seema Saxena

Abstract


Now days the role of Power Quality is increased in Electrical Network. The term Power Quality (PQ) refers to the “Any kind of issue arises in frequency, voltage and current due to which equipment gets failed or misoperates”. Electrical system is very sensitive to these issues. Specially the distribution network is very concerned about unbalances because the equipment’s used in the network specially in industries is sensitive to current as well as voltage variation and even this can cause complete shutdown. To mitigate the current related issues and fulfilling the reactive power demand of the system Shunt Active Power Conditioner (SHAPC) is used. With the help of SHAPC problems related with currents unbalance, nonlinear current and improving power factor can be mitigate. To find out the compensation capability of Shunt Active Power Conditioner a MATLAB – SIMULINK model is used and results has been plotted.

 

Keywords: Active power conditioner (APC), current unbalance, harmonics, instantaneous reactive power technique (IRPT), power quality (PQ), shunt active power conditioner (SHAPC).
