SYNCHRONZATION DEVICES MODELING
AND SIMULATION BASED ON MATLAB
Abstract
In the power system, synchronous generator, synchronous compensation and synchronous
motor often parallel or disconnect from the Power Grid. The parallel operation of the
synchronous generator inputting into the Power system or the two parts of Lifting of parallel
operation is called parallel or synchronous operation. Generators parallel, whichever is tied for
the synchronization, and tied for self-synchronizing, request veracity and fast. The veracity can
ensure the safety and reduce the impact which caused by generator parallel operation, and the
rapidity can quickly reduce the idling loss of generators. What’s more, self-synchronizing which
can make impact current and disturb the power system, not only will cause the power system
frequency oscillations, but also make voltage dropping caused by the defects.
The synchronous operation, which is unsuccessful, not only will extend the time tied, but
also affect the stability of the power system. And also, it may reduce the frequency if failed and
not return to the normal frequency quickly and important equipments can be damaged sometimes.
With the continuous development of the level of power automation system, the development and
promotion of more advanced and convenient synchronization device was required.
This paper gives a relatively detailed study to the simulation system of synchronization
device. Firstly, I studied the working principle and various components of synchronization
device, including the unit of voltage regulation, frequency modulation and closing. Then I used
MATLAB/Simulink building a simulation model of synchronization device. Finally, I used three
examples(voltage, frequency and phase) and made a dynamic simulation to the model built. The
simulation results showed that the model of this synchronization device can correctly reflect its
characteristics.
