Dynamic Model Library (DML) Siemens PSS SINCAL Element and Controller Modelling

Dynamic Model Library (DML)

Requirements and Use Cases

To analyze the dynamic behavior of electrical power systems, standard models are defined by different standardization committees (IEC, VDE, IEEE etc.), which must be treated uniformly in different simulation programs and can be individualized only by changing parameters. While the classical standardization of dynamic models primarily addresses control devices for conventional generation units, type 2 generation units are gaining in importance and require the consideration of their models in dynamic simulation.

Solution

The PSS?SINCAL Platform contains a library of dynamic models (DML) for different network elements and calculation types that can be connected to the respective network model by the user.

The following dynamic models are included in the global library of the platform:

• Inherent models, which are used by default in PSS?SINCAL in the absence of user-defined dynamic models on the network elements, to simulate the basic dynamics of the network elements
• Generic models for representation of dynamic behavior of loads, general shunt and serial branches and distributed generation plants. These can be used both as the equivalent of the complex behavior and as a starting point for the creation of user-defined, dynamic models: Variable power (GNE-P/Q),? Variable shunt admittance (GNE-Y),? Variable serial admittance (GNE-Y4), Current injection (GNE-I), Voltage injection (GNE-V)
• Models of machine control devices: (1) according to the IEEE, IEC (CIM CGMES) standards, the PSS?E definition and other specifications, (2) Excitation systems, compensators, limiters, power system stabilizer, speed/power governors
• Generic inverter-based models: Distributed energy resources according to WECC, EPRI (e.g. DER_A, PVD1)

The following dynamic models are contained in the user library in the Documents folder of the user:

• Flexible AC transmission systems (FACTS) models for load flow and stability calculations: Static var compensator (SVC), STATCOM (SVC Plus), Mechanically switched capacitors (MSC), Thyristor controlled series capacitor (TCSC)
• Simple three-phase photovoltaic model
• Dynamic models of wind turbines with different generator concepts: Asynchronous machine with squirrel-cage rotor (SCIG), Doubly fed asynchronous machine (DFIG),? ? Synchronous machine with full converter (FCSG)
