    The objective of my Bachelor’s thesis is to implement an over-voltage protective algorithm in VHDL hardware description language. The algorithm is used as a protection in power system protection. A protective algorithm is intended to run as a real-time application on the basis of 24/7/365 (365 days a year) system. It is imperative that no falling out or stopping happens with a protective device based on such system. This is not only because enormous damage/cost would be caused, but also because it would put human lives in danger. My final work provides such a reliable algorithm. With readers of the thesis in mind, I prepared a simple introduction to EES and the basics of protection for better understanding of my work. I classify protective devices according to chronology into groups and describe their characteristics. This helped me to classify my over-voltage protection algorithm and to define its working, use and demands in programming. Before coding the program, I prepared a design document of such an algorithm. I tried to present its functioning and define all the possible conditions to be kept in mind. It is important to foresee and predict any problems and complications with the device at any time during its performing. With the design document, a programmer also defends the way of working on the assigned project. I used the Active-HDL tool to code the program in VHDL language. I also used the same tool to test and simulate the program. Algorithm performance and the result are provided.
