SSE Remote Telemetry Unit SSE RTU
Telemetry Systems …40-20 Years Ago Rural Pumping Schemes – Controlled by hand Urban Schemes – Controlled by Relay Logic & Instrumentation Very Basic Telemetry Systems – Hard Wired with Mimic Radio Telemetry – Starting to emerge for remote control.
…15 to 20 Years Ago Demand for Operational Function – Alarms & Remote Control Slow Radios (300 Baud) Installed – Limited Data Throughput Cable Replacer Type Telemetry System Control – Relay Logic/Basic PLC Small Amount of Data – Mainly Basic Alarming & Limited Control Master Station – Mainly Mimic Panels & DOS Based SCADA
Typical Telemetry Network – Then!
Scada Application Evolution of Technology Driven by two main influences 1. From Client Side (Pulling forces): Plants and distribution networks got more complex. The demand for more information at a quicker rates. Better / Faster service delivery. 2. From Technology offerings (Pushing forces): New technologies offer better and smarter solutions Faster processing power. More robust communication networks.
Modern RTUs Compact – more I/O with smaller footprint Connect to all wide area networks – compatible with new IP based networks Intelligent – PLC Based processing capabilities OPC Compliant Software – open standard for industrial applications Remote Diagnostics – Network wide fault finding and configuration tools Support for IEDs – protocol support for intelligent devices Protocol Standardization
Client Requirement driven. Technology driven. Follow well established engineering practises. Hardware & Software are modular in design. To design products that are: Economical User friendly Open Compatible Expandable Always backwards compatible to older version RTUs SSE Design Philosophy
