A rapid turbine shutdown results in a load shedding to zero, which means that a power plant is suddenly no longer available to generate electrical energy. What effects does this have on the frequency and why?
global frequency average - regional scatter
Aug 04, 2019 16:51 The frequency is considered to be approximately identical at any place in Europe. However slight differences can be seen at very high temporal resolution of the frequency. While the frequency still looks almost identical in the seconds range, small differences appear in the tenths of a second range.
