Note that the field voltage Vf reaches its limit without saturating in most of the models.Īfter fault clearing and islanding, and for all excitations models, the SM mechanical power increases from its initial value of 0 pu to the final value of 0.80 pu required by the resistive and motor load (2.49 MW). The results obtained with the AC4A and DC2A models are less efficient: the system takes longer to stabilize, the stabilization of terminal voltage Vt is obtained after 6 seconds. The stabilization of the terminal voltage Vt is obtained in less than 2 seconds with the ST1A model and less than 3 seconds with the AC1A model.
Asynchronous generator matlab simulink code#
However, the generated code is customised for VxWorks. These blocks generate asynchronous Function-call control signal. The Simulink Coder library contains a section 'Interrupt Templates' with 2 blocks: Task Sync and Async Interrupt.

However, the ST1A and AC1A models provide better stability. MATLAB: How to generate asynchronous Function-call signals for the custom target in Simulink Coder. Simulation results obtained with the different excitation systems exhibit good stability when the fault is cleared. In the scopes check that the simulation start in steady-state. For the ST2A model, an additional line representing the initial value of terminal current It0 is set to 0.2739 pu.ĩ. Note that the initial values of all models have been already presaved with the same initial values.

Right-click the EXCITATION block then select the type of excitation system you want to simulate. This diesel generator matlab simulink, as one of the most functioning sellers here will categorically be along with the best options to review. Open the EXCITATION block and note in the Initial values tab that the initial values of terminal voltage and field voltage are set respectively to 1.0 and 1.4273 pu.Ĩ. Note that the initial value of mechanical power has been set to 0.00027 pu (844 W) by the Load Flow tool.ħ. The value of the constant block connected to the torque input of the asynchronous motor has also been automatically set to 7964 N.Ħ. Open the SM and ASM blocks and note that the initial values have been updated by the Load Flow tool. Press the 'Apply' button to apply the load flow solution to the model.ĥ. The table now display the actual machines active and reactive powers.Ĥ. Press the 'Compute' button to solve the load flow. A summary of the load flow settings is displayed in a table.ģ. In the Powergui menu, select 'Load Flow'. The "Active power generation P" parameter is set to 0.įor the asynchronous motor: The "Mechanical Power" parameter is set to 1.492e+006 W (2000 HP).Ģ. The Load flow parameters of the machine and motor are defined in the Load Flow tab of the two blocks:įor the synchronous machine: The "Generator type" parameter is set to "PV", indicating that the load flow is performed with the machine controlling its active power and terminal voltage. To start the simulation in steady-state, the synchronous machine and the asynchronous motor need to be initialized by the Load Flow tool of powergui. A three-phase to ground fault occurs on the 25 kV system, causing opening of the 25kV circuit breaker. The 25 kV network is modeled by a R-L equivalent source with a short-circuit level of 1000 MVA and with a 5 MW load. A plant consisting of a resistive and motor load is fed at 2400 V from a distribution 25 kV network through a 6 MVA 25/2 kV Wye-Delta transformer and from an emergency synchronous generator/diesel engine unit.
