Abstract

In this paper, the intelligent cathodic protection of underground pipelines is presented using the photovoltaic power system. The structure of the system is as follows: solar cell array converts irradiation to electrical energy and acts as a voltage source. The high DC voltage generated by the module must be attenuated to provide an appropriate voltage for the batteries by using buck converter.  The battery and the Buck - Boost converter are connected to the output of the buck converted and in final the circuit of the pipeline and the anode-bed is feed by the Buck - Boost converter. The power delivered from the module is very sensitive to the point of operation, and the converter should therefore incorporate a function for tracking the maximum power point (MPPT). In this paper new controller is designed so that, to take maximum power delivered from the solar array, therefore the overall efficiency of the system is improved significantly. Moreover, a new circuit model is proposed for underground pipelines and can be used in the simulation of cathodic protection systems. In simulation, the worst conditions have been considered to increase the lifetime of the system and to cause the designed system to be useful in different climatic conditions.
