A power plant controller is an essential component of a power plant; more specifically, it is a component in the grid connection point (GCP) where relevant information is exchanged between the plant and the grid operator.
“WAGO Power Plant Control” is a library with a control algorithm for active and/or reactive power certified per VDE-AR-N 4110/4120. It can be used on the second-generation PFC200 Controller. This controller has two ETHERNET ports, which can be used as switches, or separately over two isolated networks. This makes it possible to communicate directly from the controller with the grid operator and direct marketer, through a VPN tunnel with secure end-to-end encryption – for example, via standard protocols like IEC 60870 -104/101 and Modbus® or ripple control receivers, etc. This allows transfer of the active power, the reactive power or the power factor cos phi, among other things. The overall system allows customers to implement tailored power plant controllers.
All information, datasheets, the manual, the simulation model, certificates and a 30-day trial version are available for download as a compact file.
The percentage of renewable energy in the power grid is increasing, and we want this increase to continue – but without endangering the stability of the grid. For this reason, the technical connection rules (TCRs) for decentralized power plants have been made tightened. A central element of this is a power plant controller, which must have a corresponding component certificate, or else it cannot be put into operation and connected to the grid. However, only companies certified per ISO 9001 can get this component certificate.
