Power factor correction
Power Factor Correction
Our company is able to improve the energy consumption of your plant or corporate facility, to implement remedial solutions or power factor correction so that electricity can be used more rationally and efficiently. This is achieved by improving one of the measures used in industry to determine or calculate the degree of efficiency with which energy is used, called “power factor”.
Optimizing Electrical System Performance
The operational behavior of a plant’s machinery and equipment (refrigeration, motors, boilers, transformers, fluorescent lamps, etc.) depends on the calculated “ACTIVE POWER” (KW) in conjunction with the calculated “Reactive Power “. The reactive variety does not produce direct physical work, for example on computers, but it can become significant in an industrial environment and, if not properly monitored, it can lead to a low “power factor”.
A high consumption of reactive power, the lowering of the power factor. can be caused by:
Factors such as a large number of motors, fluorescent lighting, refrigeration systems (chillers), poor grid conditions, and underutilization of electromechanical equipment can lead to high reactive power and a low power factor. This increases current in the internal distribution system, causing power losses. Reducing the reactive current lowers these losses, improving the efficiency of active power (kW) delivered through the system.
Consequences of not correcting a low power factor:
Poor power factor can lead to higher electricity bills, increased current intensity, and conductor losses that raise temperatures and shorten insulation life. It can also require larger investments in generation equipment, oversizing of transformers and power plants, and greater demands on transmission and distribution lines. Frequent brownouts and voltage fluctuations may further decrease power factor, affecting the stability of the electrical supply. To manage these issues, electricity companies often apply demand charges based on KVA, which accounts for reactive energy consumption.
Solutions for correcting a low power factor
Our company provides real-time power factor correction, using microprocessors dedicated to this function, which are responsible for improving the calculation settings used to monitor the phase shift between current and voltage caused by inductive charge effects and thus make such factor corrections as the system may require.
The degree of power factor correction and system size depend on the power demanded by the industrial plant ; the capacitor banks are segmented in stages for a proper correction, so that if system conditions improve, and some of these segments start to cause over-correction, they can be switched off, thereby keeping our power factor stable and allowing the capacitors to discharge so they can be connected again at any time for further correction. In this manner we can maintain stable parameters, enabling us to improve your electrical systems’ operation and to ensure that it stays within proper boundaries.
Load Studies & Analysis (PF, Flickers, Transients, F0 , Harmonics) We perform studies to detect electric disturbances (Flickers, transients) and load imbalances in supply lines. The Flickers and transients are widely known in the form of surges and spikes. They are a common power quality problem in electrical utility grids (voltage flicker or variation).
Consequences of flickers and transients: Software and hardware problems.
They can damage equipment connected to an electrical grid.
They usually are very hard to detect because they occur over very short periods.
Solution to flickers and transients: Studies can be performed to determine the magnitude of these problems in the electrical grid; and then solutions can be suggested on the basis of an analysis of connected loads.
