Digital Based Solutions for the Refurbishment of Existing Hydro-generators

The modernization of existing power generators is one of the key priorities of electricity producers around the world. In order to achieve the digital interconnection of synchronous generators, located largely in hydro-power plants, it is necessary to use an appropriate excitation system. This paper presents an overview of the main objectives to be met by electricity producers in Romania. A model for experimental studies is also presented. The main purpose of this paper is not only to present the current situation in this field, but also to identify some solutions and trends regarding the modernization of the existing generators, in order to meet the requirements of the existing norms and standards, system and the software, and, also, testing its operational efficiency.
