| 摘 要： | 含小水电配电网的电能质量问题日益突出,现有无功补偿难以解决,提出在含小水电的配电网中应用DSTATCOM的思路。基于Matlab/Simulink仿真平台,建立了含小水电配电网的理想模型及配电网中DSTATCOM控制仿真模型。分别对枯大和丰小两种极端运行方式进行仿真,结果表明,DSTATCOM能有效解决丰水期电压偏高和枯水期电压偏低的问题;DSTATCOM补偿在线路末端对改善节点电压的效果优于补偿在线路中间。 |

| Abstract: | As the power quality problem in distribution networks containing small hydropower is increasingly prominent,which is difficult to solve by the existing reactive power compensation,a thinking of using DSTATCOM in distribution networks containing small hydropower was put forward. Based on Matlab / Simulink,an ideal model of distribution networks containing small hydropower and control model of DSTATCOM were established. Through simulations of two kinds of extreme operation modes including dry-big and wet-small modes,the results show that DSTATCOM can effectively solve the problems of high voltage in wet water period and low voltage in dry water period. Besides,to improve the node voltage,the effect of DSTATCOM compensation in the end of line is better than that in the middle of line. |
