Certification

The certification of TwinCAT Power Plant Control as a PGP controller confirms conformity with the following standards (see References):

Regulatory principles

The EU Regulation (EU) 2016/631 is also known as the Network Code Requirements for Generators (NC RfG) and forms the legal framework for the grid connection conditions for power generating plants in Europe. The EN 50549-2 standard specifies these requirements by describing detailed technical requirements for the connection.

In addition, national regulations, such as VDE-AR-N 4110, 4120 and 4130 in Germany, close the gap between the Europe-wide specifications of the NC RfG and the technical specifications of the EN standards. They thus create binding rules for grid integration at national level.

The FGW TR3 (Technical Guideline 3 of the Fördergesellschaft Windenergie und andere Dezentrale Energien e.V.) describes the determination of electrical properties of power generating units and plants within the scope of type and component certifications. It specifies the methods and test procedures used to verify electrical behavior in relation to the grid.

PPPiREE (Polskie Porozumienie Producentów i Rozdzielców Energii Elektrycznej) is the Polish industry organization for electricity producers and distributors that, among other things, coordinates the technical implementation of EU Regulation (EU) 2016/631 (NC I RfG) in Poland. It establishes guidelines and technical specifications that convert European grid connection requirements into national regulations.

• The NC RfG specifies the requirements that must be met.
• EN 50549-2 defines how these requirements are to be implemented in practice.
• VDE-AR-N 4110, 4120 and 4130 define this implementation for Germany
• The PPPiREE defines this implementation for Poland
• FGW TR3 defines how the requirements are to be tested and certified.
