Used tools:

To carry out refinement calculations, we have the ability to use software packages Simulink, E-TAP, MathCAD. When performing network analysis, software packages FLUKE PQ-Analyze, PQS Sapphire are used. Analyzers Pure BlackBox (Israel) and an analogue FLUKE-1760 from LEM (Austria) are used to carry out instrumental examinations of electrical networks.

The main advantages of implementing reactive power compensation systems:

• Reduction of charges for consumed reactive electricity;
• Increasing the capacity of electrical networks;
• Reduction of losses in the network - reduction of expenses for paying for active power;
• Improvement of power quality - voltage stabilization and improvement of sinusoidality (reduction of harmonics);
• The minimum payback period for the proposed solutions.
