Development of OTP Based Switch System for Power System Infrastructure Security and Personnel Safety

Electricity board in most of the countries is partially automated and the challenges faced due to cyber and infrastructure security must be dealt with to transform the system into fully automated. This work focuses in identifying a comprehensive set of cyber security challenges and need for security at multiple levels of the cyber physical power system mainly infrastructure security and personnel safety. The main challenge faced by electricity board is considered and solved using ICT. The research efforts are taken to ensure the substation and personnel safety using OTPs as they are not vulnerable to cyber-attacks since it will no longer be valid. This OTP concept is being used for electric lineman safety system and infrastructure security. In the conventional system there is a single password which is common and if any misuse leads to electrical accidents to the line man when they are in the maintenance and control of electric line repair. This is due to lack of communication and coordination between the maintenance staff and the electric substation staff. A onetime password based switch is implemented for the opening and closing of relay using Arduino and Proteus for software and hardware control. During natural calamities like flood, rains, and lightning the power system network will be damaged if the line is live. Hence the power system infrastructure security will be enhanced using this OTP method.
