Georgia Power

The Challenge

Integrate a full spectrum of utility-grade photovoltaic power generation equipment into a single SCADA system.

Georgia Power embarked on a mission to construct a power plant-scale solar field, which required the integration of diverse utility-grade photovoltaic power generation equipment into a single SCADA system. This included inverters, trackers, soiling monitoring stations, meteorological stations, substation power meters, and relays. The team at Georgia Power also required technology that their maintenance and operations groups would be familiar with to ensure long-term operational support.

The System

Build a SCADA system with an intuitive interface to monitor and control equipment from various manufacturers in one graphical environment.

Vertech implemented a full Allen-Bradley / Rockwell Software package, 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.
