Generators exchange system

Since Sudan is a country with insufficient electricity infrastructure to meet the demand of users, there is often an interruption in the electricity supply. To overcome this problem, the hospital in question has equipped itself with two 800 kVA generators, one in backup to the other, capable of covering the entire requirement.
Since the exchange system between the city line and the generators was more than fifteen years old and having been modified several times without having kept track of the various modifications, it was malfunctioning and risky for guaranteeing the continuity of hospital activities.
To respond to the needs of the problem, I redesigned the exchange system from electromechanical to electronic management, using the control units of the two generators involved directly, simplifying the operating philosophy and at the same time reducing possible points of failure.
