Smart Grid Power Distribution

Design Note #62

Smart Grid Power Distribution

Severe operating conditions, high reliability and lethal voltage potentials are typical features of power distribution systems. OTEC was hired to perform the design of this multi-function, multi-protocol smart grid power distribution controller. Design flexibility was a critical feature. Multiple isolated solid state and relay high voltage output stages make this universal controller flexible enough for the most complex installation. Diverse optically isolated input structures provide flexible monitoring functions. High performance distributed microprocessors permit flexible alternating current transmission system control. Efficient power control, power flow monitoring and data collection enhances Grid 2030 automated power delivery networks. Advanced demand-side management algorithms execute efficiently.

Multiprotocol Communications

Multi-channel RS232, RS485, Ethernet, and multi channel CAN Bus communications with on-board multi-port CAN Bus gateways implement secure highly robust communications links. Local CAN Bus communications are supported using on-board gateways operating at speeds from 1Mbit to 10Kbits per second. Secure, CRC protected, 11 bit or 29 bit CAN ID messages are supported. Dual USB channels complete the communications picture. Removable SD Cards provide a software upgrade path,secure key management, and data logging storage.

Redundant and Environmentally Tough

The multi-protocol controller operates over extended conditions from –40 C to +85 degrees C; without fans. Designed for compliance with UL60950, EN60950, CSA C22.2 safety and EN61000 immunity requirements. Redundant processors provide self-supervisory functions.
