Frequency Domain and Resonances (FRD) Siemens Advanced Dynamic and Transients Modules powered by PSS NETOMAC

Frequency Domain and Resonances (FRD)

Requirements and Use Cases

When dimensioning equipment in electrical power systems, it is necessary to efficiently determine potential resonance points of the network as well as of the active network elements over a broadly defined frequency range. This makes it possible to prevent possible damage caused by resonances in network operation through passive and active countermeasures.

•  Analysis of the frequency response of passive network elements to determine electrically induced resonance points
• Support in the sizing of filters based on the results of the frequency response determination
•  Consideration of dynamic equipment such as machines, their drive trains, their control devices and controllable network elements in the frequency response
• Consideration of the operating point in the linearized response of the frequency response of a nonlinear system

Solution

In addition to the harmonics (OB) module, the expert mode (ExpMode) of the PSS®NETOMAC transient engine allows the passive (ST, EMT modules) and active (EMT module) system behavior in the frequency domain to be analyzed by this module (FRD). It supports the user in the detection of potential resonance points and in the development of appropriate countermeasures in dimensioning and parameterization.

Quick and easy identification of resonance areas of the network

• Use of proven and successfully validated models and simulation methods of the PSS®NETOMAC transient engine, taking the torsion data (TOR module) and used models into account
•  Application of efficient linearization rules for model blocks to determine the frequency response
• Consideration of models for network elements in the passive frequency response
• Support in the sizing of filters to suppress or shift resonance ranges
