Description

The Synchronous Machine Model 2.1 block models a synchronous machine with one field winding and one damper on the d-axis and one damper on the q-axis. You use fundamental or standard parameters to define the characteristics of the machine. This block contains a dq Park transformation, so use it only for balanced operation.

Synchronous Machine Initialization Using Load-Flow Target Values

If the block is in a network that is compatible with the frequency-time simulation mode, you can perform a load-flow analysis on the network. A load-flow analysis provides steady-state values that you can use to initialize the machine.

For more information, see Perform a Load-Flow Analysis Using Simscape Electrical and Frequency and Time Simulation Mode. For an example that shows how initialize an synchronous machine using data from a load flow analysis, see Synchronous Machine Initialization with Loadflow.

Equations

The synchronous machine equations are expressed with respect to a rotating reference frame, defined by

$θ_{e} (t) = N θ_{r} (t),$

where:

θ_e is the electrical angle.
N is the number of pole pairs.
θ_r is the rotor angle.

The Park transformation maps the synchronous machine equations to the rotating reference frame with respect to the electrical angle. The Park transformation is defined by

$P_{s} = \frac{2}{3} [\begin{matrix} \cos θ_{e} & \cos (θ_{e} - \frac{2 π}{3}) & \cos (θ_{e} + \frac{2 π}{3}) \\ - \sin θ_{e} & - \sin (θ_{e} - \frac{2 π}{3}) & - \sin (θ_{e} + \frac{2 π}{3}) \end{matrix}] .$

The Park transformation is used to define the per-unit synchronous machine equations. The stator voltage equations are defined by

$e_{d} = e_{d}^{"} - R_{a} i_{d} + x_{q}^{"} i_{q}$

and

$e_{q} = e_{q}^{"} - x_{d}^{"} i_{d} - R_{a} i_{q},$

where:

e”_d and e”_q are the d-axis and q-axis voltages behind subtransient reactances.
R_a is the stator resistance.
i_d and i_q are the d-axis and q-axis stator currents, defined by

$[\begin{matrix} i_{d} \\ i_{q} \end{matrix}] = P_{s} [\begin{matrix} i_{a} \\ i_{b} \\ i_{c} \end{matrix}] .$

i_a, i_b, and i_c are the stator currents flowing from port ~ to port n.
x”_d and x”_q are the d-axis and q-axis subtransient reactances.

e_d and e_q are the d-axis and q-axis stator voltages, defined by

$[\begin{matrix} e_{d} \\ e_{q} \end{matrix}] = P_{s} [\begin{matrix} v_{a} \\ v_{b} \\ v_{c} \end{matrix}] .$

v_a, v_b, and v_c are the stator voltages measured from port ~ to neutral port n.

The rotor voltage equation is defined by

$e_{f d} = R_{f d} \cdot i_{f d},$

where:

R_fd is the resistance of rotor field circuit.
i_fd is the per-unit field current using the synchronous machine model reciprocal per-unit system.
e_fd is the per-unit field voltage using the synchronous machine model reciprocal per-unit system.

The voltage-behind-transient-reactance equations are defined by

$\frac{d e_{d}^{"}}{d t} = \frac{(x_{q} - x_{q}^{"}) i_{q} - e_{d}^{"}}{T_{q 0}^{"}},$

$\frac{d e_{q}^{'}}{d t} = \frac{E_{f d} - (x_{d} - x_{d}^{'}) i_{d} - e_{q}^{'}}{T_{d 0}^{'}},$

and

$\frac{d e_{q}^{"}}{d t} = \frac{e_{q}^{'} - (x_{d}^{'} - x_{d}^{"}) i_{d} - e_{q}^{"}}{T_{d 0}^{"}},$

where:

x_d and x_q are the d-axis and q-axis synchronous reactances.
T”_d0 and T”_q0 are the d-axis and q-axis subtransient open-circuit time constants.
E_fd is the per-unit field voltage using the exciter model nonreciprocal per-unit system.
x’_d is the d-axis transient reactance.
e’_q is the q-axis voltage behind transient reactance.
T’_d0 is the d-axis transient open-circuit time constant.

The rotor torque is defined by

$T_{e} = e_{d}^{"} i_{d} + e_{q}^{"} i_{q} - (x_{d}^{"} - x_{q}^{"}) i_{d} i_{q} .$

These defining equations do not describe the parameters you can set in the dialog box. To see their relationship with the equation coefficients, see the book of P. Kundur about understanding, modeling, analyzing, and mitigating power system stability and control problems [1].

Display Options

You can perform display actions using the Electrical menu on the block context menu.

Right-click the block and, from the Electrical menu, select an option:

Display Base Values displays the machine per-unit base values in the MATLAB^® Command Window.
Display Associated Base Values displays associated per-unit base values in the MATLAB Command Window.

Variables

The Variables settings allow you to specify the priority and initial target values for block variables before simulation. For more information, see Set Priority and Initial Target for Block Variables.

For this block, the Variables settings are visible only if, in the Initial Conditions settings, the Initialization option parameter is set to Set targets for rotor angle and Park's transform variables.
