【摘要】：隨著大規(guī)模風(fēng)電的接入,電網(wǎng)的風(fēng)電滲透率越來(lái)越高,由于風(fēng)電本身所具有的波動(dòng)性和間歇性等特征,其對(duì)電網(wǎng)的影響也日趨明顯,引起了研究人員的廣泛重視。研究大規(guī)模風(fēng)電接入電網(wǎng)的首要問(wèn)題是如何考慮大規(guī)模風(fēng)電場(chǎng)的等效,并在等效模型的基礎(chǔ)上研究其接入后對(duì)電力系統(tǒng)的靜態(tài)、動(dòng)態(tài)的影響和穩(wěn)定性控制策略具有重要的意義。首先,本文建立了風(fēng)電場(chǎng)的穩(wěn)態(tài)數(shù)學(xué)模型,在穩(wěn)態(tài)模型的基礎(chǔ)上分析研究了風(fēng)電場(chǎng)接入對(duì)系統(tǒng)的潮流和網(wǎng)損的影響。在MATLAB/Simulink中搭建了IEEE 3機(jī)9節(jié)點(diǎn)系統(tǒng)仿真模型和風(fēng)電場(chǎng)的穩(wěn)態(tài)模型,仿真分析了各條支路的傳輸損耗隨風(fēng)電場(chǎng)接入容量增加的變化情況,分析了系統(tǒng)的潮流分布和網(wǎng)損情況。然后,本文建立了風(fēng)速、雙饋風(fēng)電機(jī)組和風(fēng)電場(chǎng)的動(dòng)態(tài)數(shù)學(xué)模型；建立風(fēng)力發(fā)電機(jī)組中的各子模塊動(dòng)態(tài)模型,包括：風(fēng)力機(jī)的機(jī)械軸系模型、d-q坐標(biāo)系下的雙饋感應(yīng)發(fā)電機(jī)動(dòng)態(tài)模型。研究了基于動(dòng)態(tài)模型的雙饋風(fēng)電場(chǎng)的等效方法,給出了風(fēng)電場(chǎng)電氣部分參數(shù)的等值模型,仿真分析了等效前后風(fēng)電場(chǎng)對(duì)于四種不同風(fēng)速的響應(yīng)。以IEEE 3機(jī)9節(jié)點(diǎn)系統(tǒng)為例,在MATLAB/Simulink中搭建了等效前后的仿真模型,驗(yàn)證了本文的等效方法在分析大規(guī)模風(fēng)電場(chǎng)中的有效性。并對(duì)在輸電線路三相短路故障時(shí)風(fēng)電場(chǎng)的接入對(duì)電網(wǎng)母線處電壓、有功功率、無(wú)功功率造成的影響,以及等值模型和實(shí)際模型的接入情況分別進(jìn)行了仿真對(duì)比分析。通過(guò)三種不同情況下等值模型與實(shí)際模型接入電網(wǎng)情況的對(duì)比,驗(yàn)證了該風(fēng)電場(chǎng)的動(dòng)態(tài)等值模型的有效性和在并入電網(wǎng)進(jìn)行分析時(shí)的適用性。最后,在已建立的雙饋風(fēng)電場(chǎng)的動(dòng)態(tài)模型的基礎(chǔ)上,研究了基于雙饋風(fēng)力發(fā)電機(jī)組的電力系統(tǒng)穩(wěn)定器的設(shè)計(jì)方法。通過(guò)系統(tǒng)特征矩陣獲得系統(tǒng)特征根,然后依據(jù)特征根的分析結(jié)果對(duì)附加穩(wěn)定器的參數(shù)進(jìn)行優(yōu)化,達(dá)到增加含雙饋風(fēng)電機(jī)組的電力系統(tǒng)的穩(wěn)定性。基于MATLAB/Simulink仿真平臺(tái),搭建了含等效風(fēng)電場(chǎng)的IEEE 3機(jī)9節(jié)點(diǎn)系統(tǒng)仿真模型�；谠摲抡婺Ｐ蛯�(duì)該穩(wěn)定性控制方法進(jìn)行了仿真驗(yàn)證。通過(guò)時(shí)域仿真分析對(duì)比了風(fēng)電機(jī)組裝設(shè)附加穩(wěn)定控制器和不裝設(shè)附加穩(wěn)定控制器的情況。結(jié)果表明,雙饋風(fēng)電機(jī)組裝設(shè)附加阻尼控制器,并通過(guò)本文的方法設(shè)置有效的控制參數(shù),將有效的提高含風(fēng)電機(jī)組的電力系統(tǒng)的動(dòng)態(tài)穩(wěn)定性。
[Abstract]:With the access of large-scale wind power, the wind power permeability of power grid is higher and higher. Due to the volatility and intermittency of wind power itself, the influence of wind power on power grid is becoming more and more obvious. The most important problem in the study of large-scale wind power access to power grid is how to consider the equivalence of large-scale wind farm, and study the static state of power system on the basis of equivalent model. Dynamic influence and stability control strategy are of great significance. Firstly, the steady mathematical model of wind farm is established. Based on the steady-state model, the influence of wind farm access on the power flow and network loss of the system is analyzed. The simulation model of IEEE 3-bus system and the steady-state model of wind farm are built in MATLAB/Simulink. The change of transmission loss of each branch with the increase of wind farm access capacity is analyzed, and the distribution of power flow and network loss are analyzed. Then, the dynamic mathematical models of wind speed, doubly-fed wind turbine and wind farm are established in this paper. The dynamic models of sub-modules in wind turbine are established, including the dynamic model of doubly-fed induction generator based on the mechanical shafting model of wind turbine in d-q coordinate system. The equivalent method of doubly-fed wind farm based on dynamic model is studied. The equivalent model of electrical parameters of wind farm is given, and the response of the equivalent wind farm to four different wind speeds is simulated and analyzed. Taking the 9-bus system of IEEE 3 machine as an example, an equivalent simulation model is built in MATLAB/Simulink. The effectiveness of the equivalent method in analyzing large-scale wind farms is verified, and the influence of wind farm access on the voltage, active power and reactive power of the grid bus in the case of three-phase short circuit fault of transmission lines is verified. And the access of the equivalent model and the actual model are simulated and analyzed respectively. The comparison between the equivalent model and the actual model in three different cases is carried out. The validity of the dynamic equivalent model of the wind farm and its applicability in the analysis of the grid are verified. Finally, on the basis of the established dynamic model of the doubly-fed wind farm, The design method of power system stabilizer based on doubly-fed wind turbine is studied. The system eigenvalue is obtained by the system characteristic matrix, and the parameters of the additional stabilizer are optimized according to the analysis results of the eigenvalue. To increase the stability of power system with doubly-fed wind turbine. Based on MATLAB/Simulink simulation platform, A 9 bus system simulation model of IEEE 3 machine with equivalent wind farm is built. The stability control method is verified by simulation based on the simulation model. The additional stability control of wind turbine installation is compared by time domain simulation analysis. Devices and cases where additional stability controllers are not installed. The results show that, The doubly-fed wind turbine is equipped with additional damping controller, and the effective control parameters are set by the method in this paper, which will effectively improve the dynamic stability of the power system with wind turbine.
