wecopttool.pto.PTO.transduced_flow
- PTO.transduced_flow(wec, x_wec, x_opt, waves=None, nsubsteps=1)[source]
Calculate the transduced flow variable time-series in each PTO DOF for a given system state. Equals the PTO velocity if no impedance is defined.
Examples for PTO impedance and corresponding flow variables:
OWC: (pneumatic admittance)^-1 : flow = volumetric air flow
Drive-train: rotational impedance : flow = rotational velocity
Generator: winding impedance: flow = electric current
Drive-train and Generator combined: flow = electric current
- Parameters:
wec (WEC) –
wecopttool.WEC
object.x_wec (ndarray) – WEC dynamic state.
x_opt (ndarray) – Optimization (control) state.
waves (Dataset | None) –
xarray.Dataset
with the structure and elements shown bywecopttool.waves
.nsubsteps (int | None) – Number of steps between the default (implied) time steps. A value of
1
corresponds to the default step length.
- Return type:
