Fast valving automation prospects

In the event of large disturbances in the electric power system (EPS), transients that occur can be accompanied by the loss of generators out of synchronism and the out-of-step conditions appearance, usually preceding the cascade of an accident with severe consequences for the EPS. One of such consequences may be the occurrence of an emergency excess of generated active power in one part of the EPS. In this regard, there is a need for additional measures to implement targeted effects on transients in EPS. At present, there are three types of emergency automation, which main task is to maintain the dynamic and static stability of the excess area. However, the choice of the necessary automation is not a trivial task, it is necessary to know all the nuances of the emergency automation type used.
