Abstract

Practical countermeasures to prevent the occurrence of ferroresonance in floating systems are compared. Most attention is paid to the design of practical damping circuits. Existing criteria to determine the necessary ohmic load are evaluated and a new mathematical tool based on harmonic balance is presented. As the damping resistor can cause thermal overload of the voltage transformers, the use of a non‐linear damping circuit is advocated in some cases. Therefore, the proposed calculation method is extended to include the effect of non‐linear damping.

The power flow analysis for a floating raft isolation system consisting of constrained damped beams is completed by using the Green function, an analytical method instead of the traditional mobility approach. The transmitted power flow from a harmonic force excitation to the foundation beams via an
