SYNOPSIS: CoreTEC captures, aggregates, and persists sensor and other data within substation and distribution class electrical transformers to convert these products into IoT devices
MARKET: Industrial
  • Large transformers on the electrical power grid are complex devices with numerous sensors that capture performance and device health data. Historically that data has remained inside of the device unless captured by a manual download process.
  • ABB is developing next-generation transformers that are smart, connected, industrial IoT devices. This requires a major upgrade in the software resident in the transformers’ embedded computers.
  • A new CoreTEC system was designed with an architecture that includes a Runtime Executive, License Agent, Persistence Engine, Logging Engine, Algorithm Engine, and proxies of devices to enable persistence of data. A UI application allows operators to configure, control, and monitor the transformers.
  • The aggregation and persistence engines allow the CoreTEC system to communicate with SCADA systems, embedded devices, and remote storage and compute platforms using multiple communication paths, such as the Modbus, DNP3, RS-485, and 61850 industrial protocols, and the MQTT message based protocol popular with IoT systems.
  • The new CoreTEC system receives data from the numerous sensors and sources, aggregates it as necessary, stores timestamped data in relational and time-series databases, performs local analysis and analytical calculation, and sends the data to remote servers for storage.
  • The project also required firmware development of the Ubuntu embedded Linux board support package. In addition to modifications of several device drivers and bootstrap components, Yocto was used for deployment packaging.
  • The system was developed in C++ on Ubuntu Linux. The UI was developed in REACT.
  • The new CoreTEC software was successfully deployed after 9 months of development, at a cost dramatically lower than the client had estimated for an internally developed effort.
