For load -flow analysis enter the synchronous machine as a voltage source, using the steady-state impedances (Xd) and the magnitude of the no-load voltage. This represents the behaviour of the…

The unit is machine p.u. (rated power and rated voltage of the corresponding machine). This parameter is only used in IEC short circuit calculations.…

This value is an alternative input for the synchronous reactance. It is the permanent short circuit current in case of rated IEC conditions (1.1*Un subtransient voltage) and a direct short circuit at…

With these parameters you can specify a frequency characteristic for r and l” (subtransient inductance) for consideringskin effect and the variation of the internal inductance. Relevant for harmonics…

This flag indicates if the machine reactance should be calculated using all transient parameters (xdss, xds, xd, Tdss, Tds), or if just the subtransient reactance should be used for harmonics. There…

The attached script should be copied to the Scripts library of your project. Usage: - Select one or more lines in a diagram or in the Network Model Manager. - Right click, select "Execute Script" and…
A synchronous motor is typically started as an induction machine while a field winding resistance is also used. The "asynchronous" motor starting of a synchronous machine implies the use of rotor…
The PowerFactory synchronous machine element offers an input signal for the excitation voltage. Usually this signal is connected to a DSL model of an excitation system (AVR or EXC). This modelling…
