Export System Design

For detailed methodology, please see Export System Design.

class ORBIT.phases.design.ExportSystemDesign(config, **kwargs)

Design phase for the export cabling system.

num_cables

Total number of cables required for transmitting power.

Type:

int

length

Length of a single cable connecting the OSS to the interconnection in km.

Type:

float

mass

Mass of length in tonnes.

Type:

float

cable

Instance of ORBIT.phases.design.Cable. An export system will only require a single type of cable.

Type:

Cable

total_length

Total length of cable required to trasmit power.

Type:

float

total_mass

Total mass of cable required to transmit power.

Type:

float

sections_cables

An array of cable.

Type:

np.ndarray, shape: (num_cables, )

sections_lengths

An array of length.

Type:

np.ndarray, shape: (num_cables, )

run()

Runs the design model.

property total_cable_cost

Returns total array system cable cost.

property detailed_output

Returns export system design outputs.

compute_number_cables()

Calculate the total number of required and redundant cables to transmit power to the onshore interconnection.

compute_cable_length()

Calculates the total distance an export cable must travel.

compute_cable_mass()

Calculates the total mass of a single length of export cable.

compute_total_cable()

Calculates the total length and mass of cables required to fully connect the OSS to the interconnection point.

property sections_cable_lengths

Creates an array of section lengths to work with CableSystem.

Returns:

np.ndarray -- Array of length with shape (num_cables, ).

property sections_cables

Creates an array of cable names to work with CableSystem.

Returns:

np.ndarray -- Array of cable.name with shape (num_cables, ).

property design_result

A dictionary of cables types and number of different cable lengths and linear density.

Returns:

output (dict) -- Dictionary containing the output export system. Contains: - 'linear_density': 't/km' - 'sections': 'list [self.length]' - 'number': 'int'
