Microwave Links in Power Distribution - Providing Telecommunications in Power Distribution Networks
Problem Description
Monitoring and remote control of power production and distribution systems include a certain number of very critical elements, requiring a network infrastructure with extremely reliable features. For this reason, Iskra has equipped standard optical and radio telecommunication systems with many additional features. Availability is crucial for all power companies. So when talking about microwave radio, choice of radio protective schemes is practically mandatory. In case of one transmitter
failure, for example, system is able to switch over to the hot standby within 50 ms. Transmission speed is less important than extremely high availability.
Proposed solution
SDH is still very suitable for traffic and power companies due to rich schemes of traffic protection configurations, often radio/optical combined. Any configuration is able to reroute the traffic within 50 ms. To provide best availability, a combination of radio 1+1 protection configurations (hot standby, frequency diversity, space diversity) with typical SDH protective configurations can be very effective and can reach extremely high availability. SparkWave SDR is also very suitable for
optical radio and microwave transmission combination (using OPGW).
In the above basic design high availability is provided by using different 1+1 combinations. Where fibers are available, a combination of optical and microwave transmission yields in maximum availability. In case of radio or fiber optics failure, switchover to a redundant, hot-standby system is accomplished in less than 50 ms. All network elements are synchronized.
