This paper presents UK Power Networks' approach to protecting the first 33kV Quadrature-booster deployed on a distribution network including its integration with the existing protections schemes in the surrounding network. The paper will also briefly cover the control and operational considerations to effectively manage an identified network constraint using the Quadrature-booster.
This paper aims to look closely at the role of directional overcurrent (DOC) protection and investigate options for modifying the existing schemes or settings in the context of reverse power flow constraints for accommodating distributed generation in distribution networks. It will also consider alternative solutions and assess their suitability and impact from a technical perspective. The paper will...
Autoprobe is a general purpose autonomous observational platform with the capability of making Lagrangian measurements of any depth dependent property. Autoprobe can change its displacement in response to internal commands as desired, pneumatically forcing fluid into or out of a bladder. An electronic control system generates the commands from the temperature and pressure measurements, utilizing proportional...
A shipboard Telemetry Receiver Acoustic Command System (TRACS) was designed to be used for twoway acoustic communication with and relocation of underwater instruments. The design objectives were compact size, low cost, multi-purpose capabilities, and ease of operation and maintenance of the system. The telemetry receiver system utilizes a four-hydrophone array, bandpass filters and amplifiers, precision...
