name

string

p_mw

The active power of the static generator (positive for generation!)

string

≥ 0

q_mvar

The reactive power of the static generator

float

≥ 0

sn_mva

Nominal power of the static generator

float

≥ 0

scaling

An OPTIONAL scaling factor to be set customly. Multiplys with p_mw and q_mvar

float

≥ 0

type

type of generator

string

naming conventions:“PV” - photovoltaic system“WP” - wind power system“CHP” - combined heating and power system

k

Ratio of nominal current to short circuit current

float

≥ 0

rx

R/X ratio for short circuit impedance. Only relevant if type is specified as motor so that sgen is treated as asynchronous motor. Relevant for short-circuit calculation for all generator types

float

≥ 0

generator_type

can be one of “current_source” (full size converter), “async” (asynchronous generator), or “async_doubly_fed” (doubly fed asynchronous generator, DFIG). Represents the type of the static generator in the context of the short-circuit calculations of wind power station units. If None, other short-circuit-related parameters are not set

string

None/current_source/async/async_doubly_fed

lrc_pu

locked rotor current in relation to the rated generator current. Relevant if the generator_type is “async”

float

≥ 0

max_ik_ka

the highest instantaneous short-circuit value in case of a three-phase short-circuit (provided by the manufacturer). Relevant if the generator_type is “async_doubly_fed”

float

≥ 0

kappa

the factor for the calculation of the peak short-circuit current, referred to the high-voltage side (provided by the manufacturer). Relevant if the generator_type is “async_doubly_fed”

float

≥ 0

current_source

"Model this sgen as a current source during short- circuit calculations; useful in some cases, for example the simulation of full- size converters per IEC 60909-0:2016.

bool

True/False
