The main principles for modelling the dynamic behaviour of fluid storage tanks for anchored or fixed-based tanks are applied to unanchored tanks as well. However, when tanks are exposed to the uplift occurrence, dynamic equations of motion need to be modified to account for the rotation or rocking of the tank as a result of the uplift.
STATCOM or Static Synchronous Compensator is a power electronic device using force commutated devices like IGBT, GTO etc. to control the reactive power flow through a power network and thereby increasing the stability of power network. STATCOM is a shunt device i.e. it is connected in shunt with the line.
