The characteristics of wind turbine generators as well as features of the fixed pitch wind turbine generator and the variable pitch wind turbine generator are presented, emphasizing on the variable speed constant frequency ( vscf ) generating system based on doubly - fed generators and on the control system for pitch angles
在簡述風力機特性的基礎上，介紹了定槳距和變槳距發電機組的特點，重點分析了基於雙饋發電機的變速恆頻發電系統及槳葉節距角控制系統。The result of computer and analysis based on blade elements theory shows us that we can regulate the rotate speed of wind turbine rotor by changing set angle and pitch h. variable - pitch system is the key component of the whole wind turbine, which can assure safely pitch - control and brake
本文利用葉素理論，經計算分析得出：通過改變風力機安裝角可以改變槳距h ，從而改變風力機的轉速。變距機構是變槳距控制型風電機組實現變距控制和安全剎車的關鍵機構之一，它的運動由平動和轉動兩部分組成。He finds the pitch range after calculated the three important parameters through the bladed for windows software, then presents an optimized control strategy that regulate the pitch angle in terms of the wind speed. it must control the output power because the variational output power brings the variational loads. he confirms and optimizes the control strategy that the output power is the control target, the output power is divided into three parts
將功率作為系統控制的目標，將功率分成三段進行控制，在低風速區，載荷是有限的，以功率最大化作為控制目標；在額定風速附近，由於處在升力曲線斜率的變化點，功率變化較大，應盡快調整槳距角進入失速區工作，減少載荷的波動，該額定風速區的上下工作點要通過現場試驗的手段來確定；在額定風速以上，使功率維持在額定輸出，減少功率波動，並通過bladed軟體的模擬計算對控制策略進行了驗證。Finally, the experiments on the rotor bvi noise are conducted both in an aeroacoustic laboratory and at outdoors, and the noise characteristics at different locations are measured on different blade - tip mach numbers, collective pitch angles and rotor configurations. based on the experimental results, some new conclusions are presented
本文第七章分別在「消聲室」和外場進行了模型旋翼的槳-渦干擾噪聲實驗，對不同馬赫數、不同槳距角以及不同旋翼布置情況下的不同測點進行了噪聲測量，得出了一些新的結論。A variable vector propeller, called the " varivec propeller ", is under development as a new propulsion system for the undersea robot. the varivec propeller is a kind of specific propeller that is capable of continuously generating any degree of thrust in any three dimensional direction by varying blades " pitches cyclically in the process of rotation and responds easily to the slightest change in the robot
全方向推進器是一種在運動過程中螺距角可以變化的螺旋槳，該推進器是一種全新的設計，它最大特點是通過葉片螺距角在槳葉旋轉的過程中周期性的改變，產生前後、上下、左右六個方向的推力，並可以容易的對海洋機器人的微小運動作出反應。The main blades pitch angle is controlled by the up and down movements of the swashplate
