VISION BASED CONTROL AND MONITORING OF SPEED IN POWER STATIONS
Journal Title: International Journal of Management, IT and Engineering - Year 2018, Vol 8, Issue 1
Abstract
In power station electricity is generated by coupling the turbine with the generator. The turbine is rotated through steam/water in thermal power station /Hydraulic Power station. In atomic power station heat is generated through nuclear fusion and water is heated and steam is generated to run the turbine. It is essential to maintain constant speed N to maintain the frequency F. Increase/Decrease of frequency affect the domestic set up. This paper is to replace the sensor with a digital camera. This paper is focused on the measurement of speed of turbine-generator coupling at power station. Not only measuring the speed of turbine- Generator coupling is essential but also to control the speed of turbine – Generator coupling if it exceeds the rated speed of 1500 RPM. To maintain constant speed the DIP technique is suggested here.The coupling between the turbine and Generator is photographed for rated constant speed and stored inside the computer as standard image in terms of its texture feature value using local tetra pattern. When the speed of the turbine varies due to less/ excess steam/water which ultimately affect the generator speed , a digital camera which is installed near the coupling takes photograph at every 10 minutes and forward the image to the computer. When the current image does not match the standard image control signal is generated and control action is taken accordingly. To support speedy comparison of images, it has been implemented in Very Large Scale Integration. Even though, comparison algorithms are successful at software level, better results can be achieved by implementing in hardware.
