SECURE CONNECTION TO THE ENERGY TRANSITION

Solar Tracking

In recent years, solar renewable energy has become more cost-effective in generating electricity to power our communities. Renewable energy systems such as solar panels, are used to convert the sun’s electromagnetic energy into power for our everyday use. 

In order to obtain the most energy from the sun, engineers use Solar Position Algorithms (SPA) to calculate the location of the sun and align it with the renewable energy equipment. Solar collectors can increase their output from 30% to 40% when they are positioned directly with the sun’s rays. 

Solar Farm Management: Photovoltaic Network-Friendly Control

To enable communication between electricity producers and grid operators, the operators of photovoltaic power plants revert to telecontrol protocols. 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 telecontrol solutions:

• 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

Solar energy fluctuates and must be regulated.

• 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

Connection Technology: Safe, Simple Installation

In assembling a photovoltaic system, safe, simple installation is decisive. WAGO enables both: With the comprehensive TOPJOB® S Rail-Mount Terminal Blocks, photovoltaic lines are reliably and permanently connected. Disconnect and fuse terminal blocks with high voltage resistance securely isolate photovoltaic generators from inverters. Additional solutions like blocking diodes round out the offering.

WAGO simplifies installation of solar power plants.
