System Stability Analysis

The stability of synchronous motors and generators has long been a design consideration in industrial and co-generation plants, as well as utility systems. It is necessary to ensure the network, synchronous machines, and protective systems will function adequately so faults do not interrupt operation.

Where instability is shown to be a potential problem, several practical alternatives can usually be used to eliminate the source of the problem. In some situations, changes to the network can improve stability; while in others, protective systems can be installed to avoid machine damage and minimize the disturbance.

An EasyPower system stability study can include:

One form of output from a dynamic study is graphical time response or impedance plots. These plots can show variations in voltage, machine angle, frequency, line flows, and apparent impedance.
