Hello guys, due to some technical issues I was unable to bring the video earlier but finally its up here. Additionally, the actions taken by various PSOs to avoid a possible blackout has been explained simply. Let me know your feedback in the polls given in the "i" section of the video or in the comments. Share this video if you find it helpful. other Short URLs to the video: bit.ly/9pmblackout bit.ly/gridfailure bit.ly/9pm9mins

isn't there a feedback system which can take feedback from the load and regulate the steam in the scada age

Yes all automation system is there but it requires time. You can't expect the plant to momentarily change the parameters safely. The time duration for the whole change was only 9 minutes which is a very small time. Plus this was not with a single generator but the whole grid.

Brother actually Eddy and hysteresis losses are not proportional to frequency, if we replace Bm by V/f( as the voltage remaining constant ), then the relationship btw freq and losses becomes inversely proportional in hysteresis losses and in case of Eddy current losses it becomes independent of freq. So by increasing the freq losses will actually reduce

But in case of sudden unloading the frequency alongwith the voltage will increase and that too not proportionally, the voltage won't remain constant but will increase abruptly due to sudden fall in demand.

I think you don't work in Power Systems. Though the explanation is nice but there is some technical error. 1. The boiler design you drew is completely wrong. Even the nozzle symbol. Search de Laval nozzle on Google and you will find it. De Laval nozzle is used to generate supersonic steam. 2. The protection equipment of Thermal power plant act very fast. They are faster than Hydel power plant. Thermal plants can be turned off in a second. But it is undesirable and reboot takes much time. 3. On that day Thermal plants also reduced their production gradually to meet the requirements. And there are many backup pumps which were turned on to increase the load at 8PM.

Thank you very much for your feedback. I have limited experience in the same as a trainee for few months. The drawing which I have shown is just for indicative purpose so that more people can understand. I know about the speed governing and control system that works behind keeping the match between the supply and demand and as you said it's easy to shut but tough to reboot as that will take hours thus that can't be afforded as the coal fired thermal power plant is the mainstay of the entire power generation. Here I have tried to simplify the technical details with special focus on the concept of Swing Equation so that more people and even those who don't have an Engineering background can understand the scenario simply. I know a lot of things haven't been considered here which can be attributed to the complexity it will create in a single video as well as my limited experience in power plants. Thanks once again for sharing your views. I appreciate that.

@@ervivekchoubey Yes. You are correct. But the modern control system of power plants is completely digital. That's why they are very accurate and fast.
