Currently, Korean electric power system requires stability and reliability. All the systems demands a high reliability due to the characteristics of power plant. An algorithm for the redundant digital excitation control system has been implemented in this study. Excitation control system is one that maintains or controls output terminal voltage by supplying DC current to the field winding. Domestic controllers are needed as existing controllers are made in overseas so that it is difficult to maintain them properly. Thus, in this study, an algorithm for a redundant digital excitation control system was implemented with C language. The results of implementation were validated through on-site tests at ‘P’ power plant. The authors aims to assist system developers in understanding the flow of excitation system by disclosing the C-style pseudo code.
