About this course
Understanding the various technologies for power generation is vital, as each method has its own advantages, challenges, and suitability for different geographic or economic contexts. The curriculum includes a deep dive into conventional and renewable energy sources. This course therefore deals in detail about generation of electric power using Thermal (Coal), Hydro, Nuclear, Solar, Wind, Diesel and Other renewal energy sources and effect of variable load on power generation. These types of power plants need highly skilled technicians who are capable of operating various control equipment to supply uninterrupted electrical power. This course attempts to develop the basic cognitive skills required to take appropriate decisions to maintain the various generating and auxiliary equipment of power plants. Moreover, the safety precautions required to be followed by the diploma holders in various power plants is also included in this course.
