Secure Connection to the Energy Transition

The main objective of the power generation and distribution industry is ensuring power supply safety and reliability. WAGO products provide the greatest degrees of safety and quality. We have a complete line of products from electrical interconnection technologies to automation solutions.

Operators of ecopower plants fiercely compete for the cheapest kilowatt hour and must pay attention to efficiency and low costs when installing their systems. They are also required to connect systems of a certain size to the control system of the grid operator so that they can be down-regulated remotely as required. That requires telecontrol communication.

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. The WAGOSPAlib library calculates the sun’s position within 0.0003º of accuracy based on documents published by the National Renewable Energy Laboratory (NREL). This license free library can be used with WAGO PFC100, PFC200 and Touch Panel 600 Control Panel devices to help position solar arrays and mirrors.

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. 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

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.
