The frequency characteristic of electric equipment should be considered in the digital simulation of power systems.

The traditional asynchronous machine third-order transient model excludes not only the stator transient but also the frequency characteristics, thus decreasing the application sphere of the model and resulting in a large error under some special conditions.

Based on the physical equivalent circuit and Park model for asynchronous machines, this study proposes a novel asynchronous third-order transient machine model with consideration of the frequency characteristic.

In the new definitions of variables, the voltages behind the reactance are redefined as the linear equation of flux linkage.

In this way, the rotor voltage equation is not associated with the derivative terms of frequency.

However, the derivative terms of frequency should not always be ignored in the application of the traditional third-order transient model.

Compared with the traditional third-order transient model, the novel simplified third-order transient model with consideration of the frequency characteristic is more accurate without increasing the order and complexity.

Simulation results show that the novel third-order transient model for the asynchronous machine is suitable and effective and is more accurate than the widely used traditional simplified third-order transient model under some special conditions with drastic frequency fluctuations.
