runpp_3ph: Performs Unbalanced/Asymmetric/Three Phase Load flow
INPUT:
**net** - The pandapower format network
OPTIONAL:
**algorithm** (str, "nr") - algorithm that is used to solve the power
flow problem.
The following algorithms are available:
- "nr" Newton-Raphson (pypower implementation with numba accelerations)
Used only for positive sequence network
Zero and Negative sequence networks use Current Injection method
Vnew = Y.inv * Ispecified ( from s_abc/v_abc old)
Icalculated = Y * Vnew
**calculate_voltage_angles** (bool, "auto") - consider voltage angles
in loadflow calculation
If True, voltage angles of ext_grids and transformer shifts are
considered in the loadflow calculation. Considering the voltage
angles is only necessary in meshed networks that are usually
found in higher voltage levels. calculate_voltage_angles
in "auto" mode defaults to:
- True, if the network voltage level is above 70 kV
- False otherwise
The network voltage level is defined as the maximum rated voltage
of any bus in the network that is connected to a line.
**max_iteration** (int, "auto") - maximum number of iterations carried
out in the power flow algorithm.
In "auto" mode, the default value depends on the power flow solver:
- 10 for "nr"
For three phase calculations, its extended to 3 * max_iteration
**tolerance_mva** (float, 1e-8) - loadflow termination condition
referring to P / Q mismatch of node power in MVA
**trafo_model**
- transformer equivalent models
- "t" - transformer is modeled as equivalent with the T-model.
- "pi" - This is not recommended, since it is less exact than the T-model. So, for three phase load flow, its not implemented
**trafo_loading** (str, "current") - mode of calculation for
transformer loading
Transformer loading can be calculated relative to the rated
current or the rated power. In both cases the overall transformer
loading is defined as the maximum loading on the two sides of
the transformer.
- "current"- transformer loading is given as ratio of current
flow and rated current of the transformer. This is the recommended
setting, since thermal as well as magnetic effects in the
transformer depend on the current.
- "power" - transformer loading is given as ratio of apparent
power flow to the rated apparent power of the transformer.
**enforce_q_lims** (bool, False) (Not tested with 3 Phase load flow)
- respect generator reactive power limits
If True, the reactive power limits in net.gen.max_q_mvar/min_q_mvar
are respected in the loadflow. This is done by running a second
loadflow if reactive power limits are violated at any generator,
so that the runtime for the loadflow will increase if reactive
power has to be curtailed.
Note: enforce_q_lims only works if algorithm="nr"!
**check_connectivity** (bool, True) - Perform an extra connectivity
test after the conversion from pandapower to PYPOWER.
If True, an extra connectivity test based on SciPy Compressed
Sparse Graph Routines is perfomed. If check finds unsupplied buses,
they are set out of service in the ppc
**voltage_depend_loads** (bool, True)
(Not tested with 3 Phase load flow) - consideration of voltage-dependent loads.
If False, ``net.load.const_z_percent`` and ``net.load.const_i_percent``
are not considered, i.e. ``net.load.p_mw`` and ``net.load.q_mvar``
are considered as constant-power loads.
**consider_line_temperature** (bool, False) (Not tested with 3 Phase
load flow) - adjustment of line impedance based on provided line temperature.
If True, ``net.line`` must contain a column ``temperature_degree_celsius``.
The temperature dependency coefficient alpha must be provided in
the ``net.line.alpha`` column, otherwise the default value of 0.004 is used.
**KWARGS**:
**numba** (bool, True) - Activation of numba JIT compiler in the
newton solver
If set to True, the numba JIT compiler is used to generate
matrices for the powerflow, which leads to significant speed
improvements.
**switch_rx_ratio** (float, 2)
(Not tested with 3 Phase load flow) - rx_ratio of bus-bus-switches.
If impedance is zero, buses connected by a closed bus-bus switch
are fused to model an ideal bus. Otherwise, they are modelled
as branches with resistance defined as z_ohm column in switch
table and this parameter
**delta_q**
(Not tested with 3 Phase load flow) - Reactive power tolerance for option "enforce_q_lims"
in kvar - helps convergence in some cases.
**trafo3w_losses**
(Not tested with 3 Phase load flow) - defines where open loop losses of three-winding
transformers are considered. Valid options are "hv", "mv", "lv"
for HV/MV/LV side or "star" for the star point.
**v_debug** (bool, False) (Not tested with 3 Phase load flow) - if True,
voltage values in each newton-raphson iteration are logged in the ppc.
**init_vm_pu** (string/float/array/Series, None) (Not tested with 3
Phase load flow) - Allows to define initialization specifically for
voltage magnitudes. Only works with ``init == "auto"``!
- "auto": all buses are initialized with the mean value of all
voltage controlled elements in the grid
- "flat" for flat start from 1.0
- "results": voltage magnitude vector is taken from result table
- a float with which all voltage magnitudes are initialized
- an iterable with a voltage magnitude value for each bus
(length and order has to match with the buses in net.bus)
- a pandas Series with a voltage magnitude value for each bus
(indexes have to match the indexes in net.bus)
**init_va_degree** (string/float/array/Series, None) (Not tested with
3 Phase load flow) - Allows to define initialization specifically for voltage angles.
Only works with ``init == "auto"``!
- "auto": voltage angles are initialized from DC power flow
if angles are calculated or as 0 otherwise
- "dc": voltage angles are initialized from DC power flow
- "flat" for flat start from 0
- "results": voltage angle vector is taken from result table
- a float with which all voltage angles are initialized
- an iterable with a voltage angle value for each bus (length
and order has to match with the buses in net.bus)
- a pandas Series with a voltage angle value for each bus (indexes
have to match the indexes in net.bus)
**recycle** (dict, none) - Reuse of internal powerflow variables for
time series calculation.
Contains a dict with the following parameters:
bus_pq: If True PQ values of buses are updated
gen: If True Sbus and the gen table in the ppc are recalculated
Ybus: If True the admittance matrix (Ybus, Yf, Yt) is taken from
ppc["internal"] and not reconstructed
**neglect_open_switch_branches** (bool, False)
(Not tested with 3 Phase load flow) - If True no auxiliary
buses are created for branches when switches are opened at the branch.
Instead branches are set out of service
SEE ALSO:
pp.add_zero_impedance_parameters(net):
To add zero sequence parameters into network from the standard type
EXAMPLES:
Use this module like this:
.. code-block:: python
from pandapower.pf.runpp_3ph import runpp_3ph
runpp_3ph(net)
NOTES:
- Three phase load flow uses Sequence Frame for power flow solution.
- Three phase system is modelled with earth return.
- PH-E load type is called as wye since Neutral and Earth are considered same
- This solver has proved successful only for Earthed transformers (i.e Dyn,Yyn,YNyn & Yzn vector groups)
