Summary:The paper concerns reactive power compensation of nonlinear load. At the beginning power definitions and problems related to calculation of reactive power are presented. Based on the definitions, simplified distortion factor is determined. Two possibilities of reactive power compensation are analyzed. The first is equality between apparent and active power for fundamental component. The second, when apparent power of fundamental component is equal to total active power. These two possibilities are presented as an algorithm. Properties of the algorithms were tested using three load models (linear, nonlinear resistance and induction furnace - nonlinear inductance). In the last paragraph conclusions from analysis are presented.
