Abstract

Power distribution systems are very complex. For this reason, they are quite prone to failures. Therefore, it is inevitable for the operators of such systems to monitor the health status of the system in real time. Wireless sensor nodes are important tools to support this demand. However, every node needs a certain amount of energy. To prevent costly maintenance, those nodes best should not depend on any battery inside. One approach to face this challenge is to equip the nodes with energy harvesters. While this is a well solved task in High Voltage (HV) alternating current (AC) installations, for HV direct current (DC) systems the problem is not quite solved. In this paper novel approaches towards efficient energy harvesting in HVDC are presented and challenges towards implementations are faced.
