Feed-in management Connecting decentral power generation plants to the grid
The innovative solutions from Phoenix Contact help you to connect decentral power generation plants flexibly in accordance with the local requirements of the grid operator.
Decentral power generation systems need to play their part in ensuring high grid stability. The grid operators responsible specify the ranges to be maintained for grid frequency and voltage and for reactive power in their grid connection conditions for photovoltaic systems. To check these values, regulators for power generation systems (PGP) record the present voltage and reactive power at grid connection points. The respective control values for the inverters are determined based on these values.
The solution consisting of hardware and software from Phoenix Contact ensures that the engineering effort with respect to feed-in control is kept to a minimum. Along with the connection to the feed-in management system of the grid operator, individual reactive power control poses a great challenge. The grid parameters at the grid connection point are recorded by measuring devices and transmitted to a central Power Control Unit. Then, the actuating values calculated from the reactive power controller are transmitted to the inverter installed in the system.
Control cabinet solution for feed-in control
The connection of interfaces to the power provider and direct marketing company as well as the integration of external devices such as inverters can be adapted to the specific application by our Solution Partner. The user implements this on a project-specific basis. With our ready-to-install control cabinet solution for feed-in control, we have already combined all the necessary components such as the controller, network technology, and power supply in the same housing. This comprehensive solution also allows you to feed electricity from your decentral power generation plant into the power grid in accordance with VDE-AR-N 4110/20.
Any power generation systems, whether combined heat and power plants, wind power, or photovoltaic systems that feed into the German medium- or high-voltage grid must be equipped with a certified control unit – the Power Control Unit or PCU. While a manufacturer‘s declaration was sufficient in the past, a certificate issued by a DIN EN ISO/IEC 17065-accredited certification authority is now required.
Our PCU is certified in accordance with VDE-AR-N 4110/20 in Germany. It therefore implements the active power and reactive power requirements as well as monitoring the voltage conditions at the grid connection point.
- Compliant with the connection directive thanks to certification of our Power Control Unit in accordance with VDE-AR-N 4110/20
- Reliable system operation and straightforward grid connection through compliance with all technical connection requirements
- Intelligent automation solutions ensure low engineering and operating costs
- The programmed software allows you to commission your power generation system quickly
- Open interfaces allow for customer-specific extensions
With the network-capable energy measuring devices, you can monitor characteristic electrical data both centrally and on site. You can therefore gather all relevant characteristic data for your photovoltaic system using a small-scale controller and log it in an SQL database.
The energy measuring devices from Phoenix Contact provide you with the right solution for the optimal network integration of your power generation plant.
