Abstract—The flow rate of dam water in hydroelectric plants varies depending on time. The change in flow rate causes alterations in rotation speeds of turbines. Since the change in rotation speed of tribunes alters the frequency and amplitude of the produced electrical energy, the obtained electrical energy does not conform with UCTE (Union for the Co-ordination of Transmission of Electricity) standards in terms of quality. The system to be designed consists of a control unit which evaluates parameters such as blades that control the flow rate of water to turbine, motors, sensors, speed information with tacometer, amplitude and frequency information of produced electricity; and adjusts the blade position according to reference inlets. In the system to be designed in scope of the project, as different from current systems, the system check shall be carried out by Profibus (Process Field Bus)-DP (Decentral periphery) network based, which is a different approach to be presented for data communication infrastructure and its control. Therefore, higher performance shall be obtained compared to current systems in topics such as reliability, remote control, data transmission speed, real time transmission, system stability. In this method, it shall be possible to decrease the negative effects of factors which influence the quality of energy (i.e. precise control of turbine wicket gates, turbine speed and power measurement) Moreover, data transmission among hardwares shall be carried out by Fiber Optic, thus increasing data speed as well as data security and reducing network delay. As a result of the project, by the utilization of this new technology in Turkey's hydroelectric plants, foreign dependency shall disappear, new employment environments shall be created, production potential of hydroelectric energy shall be utilized more efficiently and big economic benefit shall be provided.
