Real-Time Reliability-based Dynamic] Line Rating System for TransmissionAsset Optimization

摘要

A new dynamic grid management solution that enables the optimization of transmission path capacity is presented. This methodology brings the technology of real time direct clearance and temperature monitoring together with learning-based dynamic linerating analytics. This methodology can be utilized to maximize existing transmission assets and reduce the potential safety risks inherent in current conventional methodologies. This new solution calibrates IEEE 738-2006 methodology by using known monitored weather and conductor information, thus creating accurate real time dynamic line ratings.The planning benefits of implementing methodology can also introduce flexibility for the timing of investment in new transmission facilities, and is an example of environmental and business stewardship — maximizing the value of existing facilities while reducing costs. The ultimate benefit of utilizing real time dynamic line ratings is the ability to provide accurate and reliable 24 hour forecasting. Further, applications and commensurate benefits of the real time direct clearance monitoring technology without the dynamic line rating analysis will also be indicated.
