| 摘要: |
| 为了研究局部网络间的功率传输能力,利用断面输电功率参数化连续潮流研究了断面传送功率对系统电压稳定性的影响.为了保证获得符合系统正常运行要求的无越限运行方式,提出一种旨在增加断面传输能力的最优无功补偿策略.该策略基于电力系统输电断面功率参数化而不是节点负荷参数化重新设计连续潮流算法,以此为工具给出断面传输能力裕度信息及网络弱节点信息.将连续潮流结果作为优化算法的约束,选定电压稳定弱节点为无功补偿安装节点,以节点电压越限为触发条件,应用内点法计算最小无功补偿量.仿真结果证明该无功补偿策略可以有效提升断面功率传输能力. |

| Abstract: |
| In the analysis of the interface transmission capability between local regions,the continuous power flow with interface power parameterization is adopted to study the affect of interface transmission power on system voltage stability.The optimal var compensation strategy is proposed to enhance the trans- mission capability and to ensure the normal system operation,which applies the interface power parameteri- zation,instead of the node load parameterization,to re-design the continuous power flow algorithm.T... |
