To enable communication between electricity producers and grid operators, the operators of photovoltaic power plants revert to telecontrol protocols. WAGO Controllers provide a standardized and easy-to-use interface for users based on the IEC 60870-5-101/-103/-104, 61400-25, 61850-7-420 (Server/Client), MODBUS, DNP3 standards. Advantages of WAGO's telecontrol solution:
- Direct communication between telecontrol system and power inverter or to solar system data logger
- Separate ETHERNET interfaces permit the creation of parallel networks
- Cybersecurity: Encryption that follows Europe's most stringent energy and security guidelines per BDEW and BSI
- Cloud connectivity: Connection to the cloud thanks to an MQTT software upgrade
- Password-protected Web-based management prevents unauthorized users from changing system settings
- Free function blocks for expanded capabilities, e.g., data loggers and inverters
- Implementing the respective grid operator's requirements for active power feed-in and reactive power supply
- cos ϕ or Q/U control (reactive power control) according to the characteristic
- Integration of external measurement systems from the medium voltage (network analysis devices, short circuit indicators, network and equipment protection) via Modbus TCP/RTU or other fieldbus protocols
- Recording of low-voltage performance data via 3-phase power measurement module
- Easy parameterization and configuration via visualization
- Modular design: Digital, analog and specialty I/O modules can be combined within a node
- Select from more than 500 different I/O modules
- Parameterization/configuration via Web visualization
- Programming per IEC 61131-3
- Integrated mobile radio modem
