Design of PV System for Cathodic Protection Systems
Golina Samir Adly;
Abstract
The corrosion is an electrochemical reaction between metal and the surrounding environment, such as: soil and water.
The cathodic protection system prevents corrosion of a metal surface by making the structure as a cathode while a block of metal is used as sacrificing anode. A current is passed from the sacrificing anode to the cathode using external power supply.
There are two different types of cathodic protection systems; galvanic system, and impressed current cathodic protection (ICCP).
Galvanic system (sacrificial anode) protects structures from corrosion by passing current from the sacrificial anode to protect structures. The galvanic system depends on the natural potential difference between sacrificing anode (higher potential) and the cathode (lower potential).The anode in Galvanic system is corroded.The galvanic system stops corrosion by impressing DC current.Increasing in DC current causes rapid corrosion of sacrificial anode and over protection of metallic structure. The DC supply may be obtained from a conventional source using rectifiers. The other alternative is to obtain DC supply from the PV solar system. The second alternative is discussed in details in this study. Also the hybrid system of using PV and diesel generator is considered. The criterion in deciding the optimum solution is the cost of produced kWh of the system.
