Project Summary

Kemerköy Elektrik Üretim ve Ticaret A. Ş. (KEAŞ) Thermal Power Plant plays an important role in Turkey's energy production with its structure consisting of three synchronous generators of 274 MVA each. In this project, it was aimed to modernize the generator excitation systems of the power plant and in this context, redundant, static and thyristor excitation systems were designed and commissioned. These systems provide direct current to the rotors of the generators, creating a magnetic field and thus realizing electricity generation. Thanks to their modern microcontroller-based structure, the excitation systems provide fast voltage and current regulation and directly contribute to the stable operation of the generators during generation. One of the most remarkable innovations of the project is the water cooling system used to cool the thyristor modules. This system optimizes the thermal management of high power excitation systems, extending component lifetime and reducing maintenance requirements. Furthermore, the water cooling system contributes to the compact design of the excitation boards, resulting in space savings.
