The Simulation Platform of Synchronous Machine by MATLAB
Abstract:
The utilization of transducer realizes the control of voltage’s frequency. It changes the situation that Synchronous Machine is always running with constant speed. Just like Asynchronous Machine, Synchronous machine can also be viewed as a member of the timing machine. This thesis intends to aim at the typical salient pole machine in Synchronous Machine. Some quantitative analysis are made on relations of salient pole machine among current, voltage, flux, flux linkage and torque, under the condition that some factors such as harmonic electric potential are ignored. These factors have less influence on error but greatly increase complexity of arithmetic. Thus, simplified mathematic model is established on the basis of a, b, c three phase variables. By the Park transformation, this model is transformed to d, q model which, is easy to be controlled by computer. Simulink is used to masking and linking all the parts of the system. The system can be divided into four main parts, namely power system, abc/dq transformation, simulation model of the machine and feedback control. Special blocks are designed for the four parts and a series of parameters in these parts are configured. The results of simulation show that each output has a satisfactory response when there is disturbance.
