Modelling and Fabrication of Microcontroller based Speed Control System in Hydro Turbine

This article presents the modeling and fabrication of a novel microcontroller based speed control device for the turbine which is completely operated by PLC which can be used in the place of conventional governor. The turbine speed is a significant parameter during the production of electricity. To control the speed of the turbine, the flow input fluid of the turbine is controlled through a nozzle which has spherical. On the other hand, stability and range are major setbacks for the efficiency of the turbine. These are major limitations to limit the usage of conventional governors. To overcome this, the advancements in technology that is microcontrollers which are loaded with the Arduino program system have developed to control the speed and range of turbine for stable outputs. In the current work, various output were considered like a valve opening time, discharge, and response time. From the results, it is observed that the increase in the speed of the turbine leads to a hike in a valve opening time and discharge as well response time is decreased.
