This type of panels are very useful to offer the technically ideal solution for installations that, due to the nature of their loads, must compensate reactive energy, ensuring an efficient use of the electrical network and protecting the associated equipment from phenomena caused in complex systems, such as harmonics and resonances.

KYV Engineering offers you the following solutions that will help you to compensate the penalizable reactive energy and protect your installation from damages caused by harmonics:

Capacitor bank / detuned capacitor bank: 

• A capacitor bank is a system used in industry and electrical installations to improve the quality of electrical power. Its main function is to provide reactive power compensation in alternating current (AC) systems, when there are not many harmonics in the systems.

Capacitor banks deliver capacitive reactive power, to compensate for the inductive reactive power released by loads such as motors and transformers, bringing the power factor closer to the optimum heat.

By improving the power factor, the capacitor bank reduces energy losses in the distribution system, in addition to avoiding penalties for excess import of reactive power from the system. 

• A detuned capacitor bank is a specialized capacitor bank configuration designed to compensate reactive power in installations with slightly more complex associated loads, with the presence of harmonics, minimizing the problems associated with resonance. Detuning refers to the technique used to avoid resonance that can occur when capacitor banks are connected in electrical systems with specific inductances, causing damage and possible equipment accidents.

El banco desintonizado, al igual que el banco de condensadores convencional, compensa la potencia reactiva en el sistema eléctrico, ayudando a mantener un factor de potencia adecuado. El banco desintonizado, combina condensadores y reactores, y se calcula y diseña para evitar la resonancia en el sistema. La resonancia ocurre cuando la inductancia del sistema y la capacitancia del banco se combinan de manera que producen oscilaciones amplificadas, lo cual puede causar daños a equipos eléctricos y aumentar las pérdidas.

KVG:

• An SVG (Static Var Generator), better known as KVG in K&V Ingeniería, is a type of reactive power compensator that continuously senses the electrical variables of the installation and generates reactive in a much faster way. Its main function is to stabilize and improve the power factor in electrical networks, especially in systems with variable loads and/or cogeneration, and where a fast response to fluctuations in energy demand is required.

The SVG adjusts the amount of reactive power in the electrical system to improve the power factor. It can operate in capacitive (providing reactive power) or inductive (absorbing reactive power) mode, depending on the needs of the system. 

Unlike traditional capacitor banks, which can have longer response times, the SVG can quickly adjust its output to adapt to load changes and maintain system stability through the use of power electronics.

Mixed KVG: 

• The main feature of a mixed SVG is its ability to combine different reactive power compensation technologies in a single device.

The mixed SVG combines the capability of an SVG with that of capacitor banks to provide efficient reactive power compensation. The SVG can be set to operate in capacitive or inductive mode, and for the proportion of compensation that needs to occur faster, while the capacitor banks deliver additional compensation.

If reactors are included, mixed SVG can avoid resonance problems, ensuring that the combination of capacitors and SVG does not cause detrimental oscillations in the power system.

Mixed SVG is an advanced solution that combines the capabilities of SVGs, capacitor banks and, if required, reactors, to provide more efficient and adaptive reactive power compensation. This improves power system stability and optimizes performance in a variety of applications.

• One of its main advantages is that, by combining these technologies, in addition to efficiently compensating reactants, costs are reduced compared to using a GTS of the total compensation capacity required by the system.

It is worth mentioning that the correct design and calculation of this type of solution, based on measurements of the behavior of the system’s electrical variables, are the key to its successful implementation and commissioning.

Active filters:

• An electrical active filter is a device designed to improve power quality in electrical systems by eliminating or mitigating distortions and harmonics in the electrical current. Unlike passive filters, which use components such as inductors and capacitors to filter out unwanted frequencies, active filters employ electronic technology to provide a more flexible and effective solution for power quality control.
• It offers continuous and adaptive correction for different types of distortions and harmonics. Reduces distortions and harmonics, improving power system stability and efficiency. Prevents damage to electrical and electronic equipment caused by harmonics and distortions. 
• An active filter is an advanced tool for improving power quality in electrical systems, using electronic technology to provide dynamic and effective correction of distortions and harmonics in the electrical current.
