Design of optimal power source for NIOT offshore moored buoy system

摘要

The moored buoy network maintained by NIOT has crucial role in cyclone and Tsunami warning. It is significant to have continuous, reliable real time data from these moored buoy systems. This paper explains the evolution of effective power system attained after years of experience and extensive study of buoy power system. Non-rechargeable lithium batteries are being used as primary power source because the buoy systems with Lead Acid batteries charged by solar panels are prone to damage. Later a dual battery system was implemented wherein lead acid battery would power the buoy system and in case of failure, the primary lithium battery can take over. A study is being made on installation of wind turbine on the buoy system to cater the power required for redundant charging mechanism.
