ANALYZING THE PROBLEM OF REACTIVE POWER USING MIKRO PFR120 RELAY

Abstract

Managing and operating lowvoltage distribution grids or high-voltage grids, requiring electricity supply to ensure voltage quality, improving power factors, and prioritizing generating active power on the grid to supply energy to electrical loads is very important, serving in daily life and industrial production. Therefore, reactive power compensation is an effective solution with significant economic benefits. The commonly applied reactive power compensation techniques in low-voltage power networks are fixedtype and automatic-type reactive power compensation. This paper focuses on the calculation and experiment of static reactive power compensation and automatic reactive power compensation on a 12-level capacitor model using a Mikro PFR120 relay with an MFM384 multimeter. The study compared theoretical results with experimental measurements to validate the theoretical calculations. These measurements were taken from an MFM384 multimeter and a Mikro PFR120 relay, recording parameters related to static and
automatic reactive power compensation on our model. This comparison demonstrates the accuracy of theoretical calculations. The recorded results achieved an accurate value of 98% to 100%.
