| 摘要: |
| 分析风电场并网运行存在的无功补偿及电压稳定问题的产生机理,在固定电容器组作为一种传统的无功补偿方法逐渐显现弊端时,将柔性交流输电系统(FACTS)设备运用到风电场以提高其运行的稳定性。以恒速恒频异步风力发电机为研究对象,采用变桨距控制方式。以Matlab/Simulink为平台,实现风电场的电气输电系统、各种风速的建模。在各种风速扰动和电网故障的情况下,分别对加入静止无功补偿器和静止同步补偿器的风电场进行仿真,得到的结果可以证明两者在风电场无功补偿方面的积极作用,并对两者的性能优劣进行对比。 |

| Abstract: |
| Causes of problems existing in the reactive compensation and voltage stabilization of wind farm power system are analyzed.As defects of fixed capacitor groups become obvious,the FACTS(Flexible AC Transmission System)devices are used for wind farm power system to enhance its operating stability.With the constant-rate constant-frequency asynchronous wind power generator as research object,the pitch angle control mode is applied.The electric transmission system of wind farm and different wind speeds are modeled on Matlab /Simulink simulation platform.Influences of different wind disturbances and grid faults on wind farms with SVC(Static Var Compensator)and STATCOM(STATic synchronous COMpensator)are simulated respectively.Simulation results verify the positive effect of SVC and STATCOM in reactive compensation.Their performances are compared. |
