New penalties for capacitive reactive energy in Spain

on .

CIRCUTOR reports on the recent approval of Circular 3/2020 of Spain's National Commission on Markets, the provisions of which will go into effect on 1 November 2020. Its implementation creates a new scenario in the area of power factor correction.

It establishes a penalty for injecting excess capacitive energy into the grid, commonly known as overcompensation, especially in tariff period 6 and for all consumers connected at a voltage in excess of 1 kV, meaning those who have their own power transformer.

The penalty will be applied on an hourly basis to all excess capacitive energy that exceeds a power factor of 0.98 capacitive. Expressed as a percentage, it means that on an hourly basis, the kvarC.h consumed must be less than 20% of the Kw.h. consumed. A charge of €0.05/kvarC.h is applied to excess reactive energy, similar to that currently charged for excess inductive reactive energy.

Period 6 always corresponds to: the 00:00 to 08:00 slot from Monday to Friday, and all day Saturday, Sunday and bank holidays. Note that this means around 51% of the total hours in a year.

During this period, less active energy will usually be consumed than in any other period, and therefore the chances of exceeding the consumption of the allowed kvarC.h are considerable. Consequently, there will be an even greater need for more efficient and accurate power factor correction, making it 100% necessary to measure the current in the 3 phases of the installation.

For example, to quantify the impact that this penalty could have, consider that in an installation with a 630 kVA transformer, an average excess of just 30 kvarC.h would mean a penalty of €552 over the total of the approximately 368 h a month contained in period 6, and therefore around €6600 a year (only in Spain).

1000 kVA 50 kvar 368 h 0 €/ 0 € 920 € / 11040 €

CIRCUTOR, a pioneering company and undisputed leader in power factor correction solutions, has designed a new capacitor bank that, by measuring all 3 phases, just like the utility meter, is able to adapt to the different target power factors required in each tariff period, thus guaranteeing not to incur penalties, while maintaining the electrical system at peak efficiency. This solution is intended both for new power factor correction devices and for inclusion in capacitor banks already in operation in electrical installations.

Photovoltaic solar canopies

on .

PVing Parks. Harness energy and take advantage of it where this was not previously possible.

The decrease in the cost of solar photovoltaic installations, coupled with the increase in the price of electric energy, has hastened the arrival of numerous types of innovative proposals in energy generation systems. Circutor, after years of dedication and endeavours in improving electrical efficiency, has designed a wholescale solution that integrates instant self-consumption with recharging for electric vehicles.

In addition to the generation of photovoltaic energy, the canopies are complemented with an advanced recharging system for electric vehicles, thus adding more features to the structure. Two types of systems are available for charging electric vehicles associated with solar photovoltaic canopies. On the one hand, the WallBox or charging points, that are integrated directly into the foot of the canopy; alternatively, the option with Urban r posts may be chosen, thus offering a dual socket, in addition to built-in communications, giving freedom to the user to decide the place of the installation, not being integrated into the canopy's primary structure.

Solutions for Protection and Monitoring of photovoltaic plants

on .

Photovoltaic generation

Climate change and global warming are already a reality, and the only option we have to change this situation is the use of efficient and sustainable energies that assure us that our planet will be a habitable place for future generations.

The aim is not only to promote renewable energy but also to seek maximum efficiency for this type of installation. Therefore, we need systems capable of permanently monitoring, supervising and managing the facilities and interacting with all their elements, ensuring their optimum performance.

CIRCUTOR Combiner Box

The CIRCUTOR proposal consists of a solution based on the Combiner Box and the STM system.Monitoring must not only consist of the measurement of the parameters of a PV installation and its massive sending to the control centre.Therefore, currently the STM systems, which are integrated into the Combiner Box, incorporate a powerful analysis and management capacity that guarantees, at all times, the maximum performance of the photovoltaic plant.

If we add to this management capacity the integration of wireless communications based on LoRa technology, a reduction in the cost of mounting the communications network can be achieved while maintaining the necessary performance for the optimal management of both electrical variables and alarms.

The complete solution involves the integration of STM systems in the Combiner Box, including all the elements associated with the protection of the strings, the fuses, the output disconnecting switch of the Combiner Box and the necessary protections in case of overvoltage.


 
Solutions for the protection and monitoring of PV plants

 

Circutor boasts different types of Combine Box models according to the needs of each facility to be installed at level 1 and level 2.

The design of these equipment can be configured according to prescription, so our design team can offer a “tailormade” solution to meet the needs of any project for the management of power generation in photovoltaic plants.

Level 1 Combiner Box monitored with Shunt

Level 1 Combiner Box monitored with Shunt
This Combiner Box has a series of inputs, which support groups of single or double strings, protecting each of the inputs from overcurrents.

Analysis of the coverage of wireless communications (Ground Mapping)

To determine the number of Gateways needed to cover all Combiner Box, first a ground mapping or theoretical analysis of the terrain is done by means of computer tools for simulating the propagation of the LoRa signal.In the following image the image of the terrain orography can be seen and with red dots the location of the Combiner Box is indicated and in the graph of the upper part the terrain relief is viewed and with a straight displaying the obstacles that exist to communicate in a straight line.

 

LoRa coverage simulation

By studying Circutor's specialists, a map of the terrain is generated where the exact position of the situation of each Combiner Box is marked in red, seeing the level of LoRa signal coverage.

LoRa coverage simulation

Once the installation points of each Combiner Box have been defined, vision graphs are made between them and the inverters to verify the coverage points of the LoRa signal, determining if the communication between them will be correct or there will be a coverage issue.The results of this analysis will depend largely on the orography of the terrain and, to a lesser extent, on the distances.

If the theoretical result is not entirely satisfactory, usually in plants with a very complex orography, Circutor offers a commissioning service, where specialist technicians travel to the installation to perform radio-frequency tests and measurements, determining exactly where to install the different LoRa Gateways, ensuring the correct communication of the monitoring system with the management centre.

Structures and support profiles for photovoltaic modules

on .

Photovoltaic solar energy is one of the most economical and consolidated renewable sources in the market today.The constant rise in the price of electric energy together with the decrease in the prices of the elements that comprise a photovoltaic installation is generating a direct increase in the implementation of these systems. Future perspectives certify it as taking centre stage in order to accelerate the energy transition on a global scale.

On a small scale, it is self-consumption that is contributing to this energy revolution. To be able to generate electricity where it is needed, to be able to consume proximity KM0 energy that uses a local, renewable and free resource.

The support structures are the elements that allow the fixing of the modules on the roofs where the photovoltaic installation must be housed, constituting a main element of the solution. Circutor offers a complete range of configurable support structures for any type of installation and roof.
