The resilience of automatic wireless meters reading for distribution networks in smart city model

The power supply for autonomous wireless sensor network nodes is crucial reliability issue for stability of the data transmission solutions. Development of methods for recognition of failures in distribution systems, like technologies for construction of measuring instruments and identifying of leakages, is based on wave principles. Control of traffic flows on the basis of graph theory, cybersecurity of infrastructure systems, models, methods and technologies for the creation of wireless networks for the translation and processing of information, ensures reliable power supply. The development of backup solution, to recover in case, if external electrical power fails, and development of nodes, which could integrate several power supply solutions, are described in this paper. The proposed node needs to be able to send notifications to the utility, demanding the use of backup energy strategies. The authors of the research offered an approach that can help to use pseudo autonomous system power supply scheme with PV panels as alternative power source for WSN nodes in particular irradiation conditions. Based on the test results, an integrated power control module parameters are developed. The novelty of the research is an approach that includes different power supply solutions in order to ensure defined signal transition quality parameters for maximum effectiveness of WSN nodes power feeding.
