| For the transmission line on-line monitoring of ice conditions, during the ice storm, ice can be used to monitor the situation and lead to real-time early warning to guide the DC device to selectively melt the ice melting ice. At the same time under normal operating conditions, the system can fully play the role of online monitoring equipment in the peak load season, the capacity increase as a dynamic application monitoring. The main subject of the calculation model of ice, communications transmission, front-end device power use, functional requirements for system software research and analysis, construction of a melting ice plant and DC transmission lines with ice-line monitoring system.This research mainly has three innovations:wireless broadband communication network OPGW cable up to the highest 100M/s channel rate; Power supply system using a high energy, low temperature, ultra-high temperature non-explosive, low self-discharge characteristics of lithium iron phosphate as the energy storage and energy supply power/solar power as the charging energy; Two tranches of three towers ice computational model, multi-modal integration and complementary ice measurement strategies to overcome the single-tower model and the shortcomings of a single tower two steps of the model can calculate the unbalanced tension and tower load changes, but also takes into account the uneven profile of concentrated load of ice conditions to improve the vertical span and calculated the accuracy of ice thickness. |
