A New Distribution Automation Solution Based On The ADSP-CM40x Processor

Power Distribution Systems - In the modern smart grid system, distribution automation systems will update to increasingly more intelligent electronic devices, which are used to monitor power quality and quickly isolate any fault from affecting the overall grid operation. Smart terminals, including DTU/FTU/TTU, are growing in use and changing grid architecture.

ADI's ADSP-CM40x system in one package, with a rich set of industry-leading system peripherals and memory, is helpful for a compact layout and reducing design time.

• Decrease the overall system cost by using 16-bit, high precisions ADCs with low cost but high performance op amps.
• Offers an additional on-chip assistant hardware module—HAE (harmonic analysis engine)—to reduce the load of the MCU for post signal processing algorithms (for example, energy metrology and FFT). Provide an easy approach for the customer to realize a metering and protection automation device.
• Support two CAN buses for enhanced back plane communication, which increases communication bandwidth or provides system-level redundancy.
• Enhanced back plane-based, system-level robustness by using a differential type communication interface.
• Integrated Ethernet MAC with IEEE1588 supported.
