Calculation of static stability limit of high voltage generator with constant active power

In order to study the static stability limit of high voltage generator, a mathematical model at high voltage generator leading phase operation is proposed; the calculation results of high voltage generator of the electric quantity of reactive power, terminal voltage, terminal reactive, terminal power angle are obtained at the static stability limit by using the analysis with constant active power. The comparison between the static stability limit of high voltage generator and conventional generator is analyzed with example. The results show that the static stability limit of high voltage generator is better than that of conventional generator. Finally, the correctness of the simulation is proved by the experiment.
