Description: 构建了一个包含风速模型、功率转换模型、传动链模型等三个部分的10MW变速直驱型风力发电机组的标么值的Matlab模型.传动链模型是基于二质量块——轴数学模型所构建的动态模型.通过标么值的转换及灵活的参数调整,该模型能较准确地模拟各种变速直驱型风力发电机组.仿真分析获取了最大功率跟踪特性曲线,并得到了风力发电机组的四个工作区.结果还能表明,电负荷电磁阻力矩能动态地调整电机转子转速,从而在低速风时能实现风能最大功率的追踪.同时,风涡轮的桨距角能控制高速风的利用率,使风涡轮机工作在额定功率下,有效地防止整个风力发电系统的机械和电负荷容量的过载冲击.作为原动力模型,该模型有助于进一步研究变速直驱风力发电系统的功率特性和并网发电控制技术.-Matlab model constructed a unit value 10MW direct drive variable speed wind turbine model three-part wind power conversion model, models, etc. contained in the transmission chain drive chain model is based on two mass- Axis constructed mathematical models the dynamic model by converting the unit value and flexible parameter adjustment, the model can accurately simulate the various speed direct-drive wind turbine simulation analysis to obtain the maximum power tracking characteristic curve and get the wind turbines four workspaces results also show that the electrical load electromagnetic drag torque motor rotor speed can be adjusted dynamically, resulting in low speed wind when the wind can achieve maximum power tracking. Meanwhile, wind turbine pitch angle can be controlled using high-speed wind rate, so that the wind turbines operate at rated power, effectively preventing overloads mechanical and electrical load capacity of the entire wind power generation system and as the driving f Platform: |

Description: of the electrical power system. At the time of transformer energization high current is drawn by the transformer known as the inrush current. This current is nearly ten times more than the full load current of transformer. It produces mechanical stress on transformer and also affects the windings and bushings of the transformer. The large switching transient current affects malfunction of protection system of power system and the different equipments connected to system. So the inrush current should be minimized. There are different methods used to minimize the inrush current such as volt second balance, series compensator, point on wave switching method etc. This paper focuses on point on wave switching method. It also explains the results for inrush current of three phase transformer with and without point on wave switching method. A test is driven on 450 kVA, 500kV/230kV grounded Y/D transformer in MATLAB/SIMLINK environment. It also focuses on Platform: |

Description: Power quality is a major concern for electrical engineers and researchers now days. Various power quality problems are voltage sag, swell, interruptions, harmonics etc. This paper discusses the problem of harmonics and its reduction in distribution network against the induction motor drive load. Harmonics distortion is reduced using Distribution static compensator (DSTATCOM) modeling in the MATLAB/ Simulink environment. The control technique used is Instantaneous power theory which calculates the required current injected into the power system. The simulated results show the effectiveness of DSTATCOM in reducing harmonics distortion. Platform: |
