EI2021 POWER PLANT INSTRUMENTATION L T P C
3 0 0 3
The course is designed to familiarize the student with the functions and instrumentation available in a modern power generation plant.
i. To provide an overview of different methods of power generation with a particular stress on thermal power generation.
ii. To bring out the various measurements involved in power generation plants. iii. To provide knowledge about the different types of devices used for analysis.
iv. To inpart knowledge about the different types of controls and control loops.
v. To familiarize the student with the methods of monitoring different parameters like speed, vibration of turbines and their control
