The generation of harmonics and reactive currents by inverters in
renewable energy plants is a problem that can have a significant impact
on the quality of the energy supplied to the grid and, therefore, on the
income of the generating companies.
reactive current
The generation of reactive power in energy systems is often one of the biggest headaches in an industrial installation for energy managers and their operators.
Energy producers
The electricity supply companies will start charging us for capacitive reactive energy. What does this mean? Normally, the capacitor bank was oversized because there were no penalties for capacitive reactive energy. Well, from November onwards there will also be a penalty for the latter. Therefore, the design of the capacitor bank from now on will have to be more precise.
How can it be corrected?
Benefits of Capacitor Banks:
* Power factor correction: Effectively, by reaching a cos φ of 1, the use of electrical energy is optimized, avoiding economic penalties.
Disadvantages and Additional Considerations:
* Own consumption: It is true that capacitor banks require energy for their operation. This consumption must be considered when evaluating the total economic benefit.
* Limited useful life: Capacitors have a finite useful life and can degrade over time, especially if they are subjected to high temperatures or overloads. It is important to perform preventive maintenance and replace them when necessary.
* Heating losses: Heating losses can be significant if the appropriate size of the capacitor bank is not selected.
* Harmonics: Capacitor banks can generate harmonics in the electrical network, which can affect other equipment. It is advisable to use harmonic filters to mitigate this effect.
D.A.F. (Dinamic Adactive Filter
D.A.F.: the ultimate solution for power quality. The latest generation device offers precise current control, eliminating the need for capacitors. With a response time of less than a millisecond, it corrects the power factor in real time in a range from 0 to 1, balancing the phases and attenuating harmonics by 100%. It optimizes the use of the generated energy, reducing operating costs and improving the useful life of the equipment. In this way, 100% of the generated current is achieved without wasting anything.
