Abstract:
In the Bulgarian electric power system are working hydro generators with total power approximately 2400 MW. They are manufactured mainly in the 60s and 70s of the past century and as a rule they don't have manufacturers P-Q diagrams which would define the reactive power work range. Modern electric power control systems require the generators to work with inductive and capacitive energy. This leads to danger of unallowable end package heating in under excited state (capacitive power) and that's why the energy system lacks the ability to use the generators voltage regulation capability. The current workout is to create an experimental method to determine the hydro generator reactive power alteration limits range, taking account of the core's end package heating.
