Stability (RMS) (ST) Siemens PSS SINCAL Core Modules

Stability (RMS) (ST)

Requirements and Use Cases

The planning and operational management of complex energy systems require analysis methods in the time domain, so that not only stationary conditions but also dynamic processes that occur in between are included in the assessment of the network state. If the dynamics of the network are shifted to the network levels subordinate to the transmission network, the complexity of the demands on the operators of such systems increases.

• Time domain analysis for compliance with the classical stability concept according to IEEE regarding voltage, frequency and rotor angle stability
• Interactions in the electrical power system to and between converter-based systems
•  Analysis of transients and stresses in the transmission and distribution network in case of symmetrical and asymmetrical events (e.g. short-circuits, start-up processes, equipment malfunctions)
• Consideration of the influence of different types of generating plants with their control and communication devices
• Verification of the protection concept in case of mutually dependent fault sequences in time domain

Solution

The PSS®SINCAL Platform with its dynamics engine PSS®NETOMAC offers the user in this module (ST) the possibility to use it for the most basic applications directly in the PSS®SINCAL GUI, as well as in the expert mode (ExpMode) to use the native user interface of the engine for advanced calculations.

In addition to precise dynamic models, the dynamics engine offers a high degree of freedom in modeling and the possibility of using it as a calculation module in other programs such as the SIGUARD® product family.

• Time domain simulation based on phasors (RMS) for symmetrical and asymmetrical networks with symmetrical and asymmetrical fault conditions, loads and power generation
• Use of proven and successfully validated dynamic models and simulation methods of the PSS®NETOMAC dynamics engine
•  Consideration of the protection device behavior during transients in the time domain simulation and in protection coordination
