Closed-loop control of the wind farm at the point of connectionĪ wind farm controller can be used to accurately control the active and reactive power of a wind farm at the point of connection (PoC). The hardware-based Remote Terminal Unit - Interface (RTU-I) supports Ethernet-based field buses such as Modbus TCP and IEC64 as well as serial field buses like Modbus RTU and DNP3. The software-based ENERCON SCADA Process Data Interface (PDI) can make data available either via the OPC XML-DA or the IEC64 protocol. Communication interfaces to the SCADA SystemĮNERCON offers a wide range of optional communication interfaces for data exchange with the SCADA system of a wind farm. As a result both real-time information and historical data are available. The ENERCON SCADA Remote software enables customers to connect directly to the ENERCON SCADA server of a wind farm from anywhere in the world. It fulfils a variety of functions with regard to communication, data recording and control in the wind farm. The ENERCON SCADA server is the central component of the ENERCON SCADA system and is connected to the WECs via the wind farm's fibre optical data bus.

Provision of such system services allows wind farm operators in many markets to generate additional income, and ensure optimal operation.

The adaptability of the standard topology consisting of ENERCON WEC and ENERCON SCADA System allows complying with the most demanding grid codes and additionally providing a multitude of system services. The Supervisory Control and Data Acquisition (SCADA) system developed by ENERCON comprises all components for data acquisition, remote monitoring and control of a wind farm.
