摘要
采用電力電子變頻裝置實(shí)現(xiàn)電壓頻率協(xié)調(diào)控制,改變了同步電機(jī)歷來的恒速運(yùn)行不能調(diào)速的面貌,使它和異步電機(jī)一樣成為調(diào)速電機(jī)大家庭的一員。本文針對(duì)同步電機(jī)中具有代表性的凸極機(jī),在忽略了一部分對(duì)誤差影響較小而使算法復(fù)雜度大大增加的因素(如諧波磁勢(shì)等),對(duì)其內(nèi)部電流、電壓、磁通、磁鏈及轉(zhuǎn)矩的相互關(guān)系進(jìn)行了一系列定量分析,建立了簡(jiǎn)化的基于abc三相變量上的數(shù)學(xué)模型,并將其進(jìn)行派克變換,轉(zhuǎn)換成易于計(jì)算機(jī)控制的d/q坐標(biāo)下的模型。再使用MATLAB中用于仿真模擬系統(tǒng)的SIMULINK對(duì)系統(tǒng)的各個(gè)部分進(jìn)行封裝及連接,系統(tǒng)總體分為電源、abc/dq轉(zhuǎn)換器、電機(jī)內(nèi)部模擬、控制反饋四個(gè)主要部分,并為其設(shè)計(jì)了專用的模塊,同時(shí)對(duì)其中的一系列參數(shù)進(jìn)行了配置。系統(tǒng)啟動(dòng)仿真后,在經(jīng)歷了一開始的振蕩后,各輸出相對(duì)于輸出時(shí)間的響應(yīng)較穩(wěn)定。

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.
