【摘要】：變槳距功率調(diào)節(jié)技術(shù)是大型并網(wǎng)風(fēng)電機(jī)組的重要技術(shù)之一。在風(fēng)力發(fā)電機(jī)組的運(yùn)行過(guò)程中,只有保證對(duì)槳葉捕捉風(fēng)能的穩(wěn)定控制,才能輸出質(zhì)量可靠、安全高效的電能。液壓變槳系統(tǒng)是目前廣泛采用的變槳距控制方式之一,研究其動(dòng)態(tài)特性和控制性能,對(duì)提高變速恒頻風(fēng)電機(jī)組的控制質(zhì)量具有重要意義。 由于風(fēng)電機(jī)組的變槳距液壓系統(tǒng)屬于涉及多種能量的復(fù)雜系統(tǒng),而鍵合圖法建模在處理多種能量間的轉(zhuǎn)換具有獨(dú)特的優(yōu)勢(shì),故本文在風(fēng)電機(jī)組變槳距液壓系統(tǒng)進(jìn)行原理分析后,利用功率鍵合圖法建立了系統(tǒng)的數(shù)學(xué)模型,并在MATLAB/Simulink的仿真環(huán)境下搭建了仿真模型,對(duì)系統(tǒng)的動(dòng)態(tài)特性進(jìn)行了分析。根據(jù)風(fēng)電機(jī)組的實(shí)際工況特點(diǎn),加入了模糊PID控制策略。結(jié)合系統(tǒng)的仿真模型,在仿真環(huán)境下檢驗(yàn)了控制效果。 考慮到液壓系統(tǒng)的復(fù)雜性,運(yùn)用了液壓仿真工具DSHplus搭建了系統(tǒng)的模型。并采用與Simulink聯(lián)合仿真的方式,結(jié)合MATLAB語(yǔ)言編寫(xiě)的模糊PID控制器程序,再次對(duì)液壓系統(tǒng)的控制效果進(jìn)行檢驗(yàn)。
[Abstract]:Variable pitch power regulation is one of the most important technologies for large scale grid-connected wind turbines. In the process of wind turbine operation, only by ensuring the stable control of wind energy capture on the blade, can the power output be reliable, safe and efficient. Hydraulic variable propeller system is one of the widely used pitch control methods at present. The dynamic characteristics and control performance of the variable pitch control system are studied. It is of great significance to improve the control quality of wind turbine with variable speed and constant frequency. Because the variable pitch hydraulic system of wind turbine belongs to a complex system involving many kinds of energy, the bond graph method has a unique advantage in dealing with the conversion between many kinds of energy. Therefore, after analyzing the principle of variable pitch hydraulic system of wind turbine, the mathematical model of the system is established by using the power bond graph method, and the simulation model is built in MATLAB / Simulink environment, and the dynamic characteristics of the system are analyzed. According to the actual operating conditions of wind turbine, fuzzy pid control strategy is added. Combined with the simulation model of the system, the control effect is tested in the simulation environment. Considering the complexity of the hydraulic system, the hydraulic simulation tool DSHplus is used to build the system model. The control effect of hydraulic system is tested again by using the method of combined simulation with Simulink and the fuzzy pid controller program written in MATLAB.
