For this project, we needed to integrate utility-grade photovoltaic equipment into single SCADA system using new technology the operations team was familiar with.
To build a power plant-scale solar field, Georgia Power required integration of a full spectrum of utility-grade photovoltaic power generation equipment including inverters, trackers, soiling monitoring stations, meteorological stations, substation power meters, and relays into a single SCADA system. The team at Georgia Power also required technology that their maintenance and operations groups would be familiar with for ensured long-term operational support.
A full Allen-Bradley / Rockwell Software package was implemented, including a CompactLogix PLC acting as the plant master controller, Micro series PLCs acting as local data concentrators, a distributed FactoryTalk View SE HMI system for plant monitoring and control, and a FactoryTalk Historian for data collection. The plant master controller collects data from all of the Micro820 PLCs via Ethernet\IP, as well as gathering soiling, meteorological, tracker, and substation data from devices throughout the plant via Modbus TCP using its in-rack Prosoft Modbus TCP modules.
The resulting SCADA system connected all components of the solar field, providing an intuitive interface through which it was possible to interact with equipment from a variety of manufacturers in one seamless graphical environment. The system requires minimal training while still allowing maximum effectiveness for operation, control, and troubleshooting of the plant.
“Over the past seven years, Vertech has proven to be a valuable partner. Vertech has always been ready to provide expertise as needed, and we look forward to a continued partnership as we construct larger and more advanced solar power plants in the future.”
