Design of Variable Reactive Power Compensator to Improve Power Factor Correction of a Static Load

摘要

The use of electrical energy on industrial loads often cause energy consumption problem which is not in accordance with the power needed by loads. The problem is caused by low loads power factor rating. Therefore, power factor correction is required by calculating installed loads capacity with the resulted power factor. Power factor correction can be done by using a magnetic energy recovery switch (MERS). MERS is a circuit located between sources and loads which control switching process on the capacitor. MERS is arranged of four MOSFET or IGBT as the switch. This research is done to know the characteristics of MERS and simulate it to correct the power factor of static loads. Static load is symbolized as RL. The specification of the load is obtained from research reference. This research implements MERS on a renewable energy source. The result of this research proves that MERS can correct static loads power factor from 0, 47 to 0, 98. The implementation on a renewable energy source showed if MERS is able to increase the value of static loads power factor.
