Effective Energy Consumption with Power Quality Improvement in Distribution

Power quality improvement for nonlinear loads is the point of interest for researches in recent years. Power factor plays an effective role in efficiency of electrical system. In power system the voltage level at different system changes with the change in load. The voltage level at the load must be maintained within required range irrespective of the type & magnitude of the load. For maintaining voltage fixed within limits, it is necessary to maintain the balance of reactive power in the system as reactive power is related with voltage directly. The appropriate choice for such problem is static Var compensators (SVCs) due to its low cost and simple control strategy. This paper proposes to minimize the harmonics and increase the power quality into the power distribution systems by the operation of SVC used in coordination with fast changing loads. We present a design and performance of TRIAC based capacitor bank switching using Arduino Uno. The performance of system is evaluated for different load conditions.
