In the course of my studies as an electrical and electronic engineering student, I was privileged to undertake a training program in Egbin Power Plc, it is arguably the largest single thermal power generating plant in black Africa with an installed capacity of 1320MW which is currently about to be extended.
It was a very insightful experience and I learned so much about the power industry.
However, for the sake of this post, I am drafting this to actually introduce the major concepts I learned first hand in the power plant and you will enjoy the series if you have a theoretical background. If you don’t, it will spur up your studies when you are being introduced to the theories of how it works.
I will be breaking down this series into the following:
- How power is generated in a thermal power plant: In this post, we provided a walk through to how power is generated in a steam power plant, from the purification of water – citing the processes common bore-hole drilled water pass through to meet process specifications and also citing what happens when these specs are not met
- Steam turbine generators and Excitation: In this post, we introduced the steam turbine generators, its working principles and how they generate power. The field flashing concept was explained and shown. And how the generator is able to sustain excitation indefinitely.
- Black start: How to start up the power generation when there is an outage or system collapse. The black start system which is made up the gas turbine generator, the diesel engine will be explored.
- Gas turbine generators: Here we explained the working principle and operation of the gas turbine generator. How it works literally using field experience and the difference or comparison between it and the steam turbine generators
- Feed Water Heaters and their relevance in a thermal power plant: Feedwater heaters are pieces of equipment and part of the various units involved in power generation. Why can’t the power stations do without the feedwater heater? Why are they placed along the lines of the feedwater? What role do they play? How economizers and deaerators are part of the feedwater heaters, are all considered within the post.
- Instrumentation and Control in the plant
- Major skill sets required from students
- Understanding elementary Electrical drawings
- Piping and Instrument Diagrams (P&ID)
Some of the articles are still under preparation, we will link to them as soon as we are done.
