摘要: |
滇西地区小水电云集,距主网电气距离远,动态稳定问题突出。为改善滇西电网的动态稳定水平和送出能力,基于受扰时序轨迹动态性能指标及投资成本建立了滇西电网分别配置SVC、STATCOM和TCSC单一FACTS元件的综合优化模型,并应用改进差异优化算法求解出滇西电网配置不同类型单一FACTS元件的最佳点和容量。计算结果表明,采用最佳单一配置SVC、STATCOM、TCSC方案时,STATCOM是改善滇西电网动态稳定水平效果最好的单一FACTS元件。 |

Abstract: |
Lots of small hydropower stations gather in the west of Yunnan province, where are far from Yunnan main power grid in electric distance, and therefore dynamic stability in this area is serious. Based on the disturbed temporal trajectory dynamic performance index and cost of investment, SVC, STATCOM and TCSC single FACTS element integrated optimization model is established respectively in order to improve the dynamic stability and transmission ability. And an improved difference evolution algorithm is applied for the different types of single FACTS element configuration parameter and capacity. The result shows that STATCOM is the best single FACTS element to improve dynamic stability Western Yunnan power grid. |
