Substation Automation Solutions

Substation automation devices add intelligence to the power grid by adding communications as well as controls and analytics functions. Communications in substations are handled by devices such as industrial routers, protocol converters, and gateways, which controls and analytics are functions of Intelligent Electronic Devices (IEDs). As renewable energy sources become more prevalent and power grids become older, larger, and have more demands placed upon them, intelligence is needed to coordinate, control, communicate, and protect various aspects of the infrastructure.

TI's ARM and DSP processors can cover all functions of substation automation equipment:

  • Scalable solutions integrate ARM cores, DSP cores, PRU-ICSS, and graphics or display
  • Control and communication- ARM Cortex-A cores
  • Measurement and analytics- TI C6x DSP cores or ARM's vector floating point unit (VFP)
  • Support for legacy or modern real-time protocols like IEC61850- TI's unique PRU (programmable real-time unit) subsystem.

Intelligent Electronic Devices have many functions: Measurement, Analytics, Control, Communication, Reliability

Single Chip Drive Solutions

A highly integrated motor drive solution enables all three core functions of a motor drive onto a single chip enabling the system to connect, control & communicate. This hybrid architecture provides the design simplicity of a compact solution while maintaining deterministic interfaces enabling real-time response to events. TI processors with the programmable real-time unit, provide high performance of a differentiated system and the flexibility to support multiple protocols in one package.

TI’s ARM processors integrates core functionalities of the industrial motor drive solution:

  • A single chip solution to bridge from motor control to higher level communications
  • Combining feedback and industrial communication protocol on a single chip allows for more integration and a smaller footprint
  • Support for certified multi-protocol industrial Ethernet through the programmable real-time unit,
  • Multi-protocol feedback interface for motor control though the programmable real-time unit,
  • Field-oriented Control (FOC) for variable-frequency drives
