| 摘要: |
| 为了方便、快捷、准确地计算出低压配电网的无功补偿配置方案，评估补偿方案的效益，协助电网运行管理人员选择经济适用的无功补偿方案，采用Access关系型数据库管理系统、Visual Basic 6.0可视化开发工具，开发了一个低压配电网无功补偿及效益评估系统。该系统具有直观、友好的人机交互界面，提供了多种配电网潮流计算方法和无功补偿优化配置计算方法，以及对不同补偿方案进行成本和效益的评估计算。系统还提供了直观的图形接口由电网运行人员输入新规划建设的低压配电网台区信息，并计算出该台区的无功分散补偿优化配置方案。应用该系统于广州市南沙区实际低压配电网台区，表明了系统使用方便，能够可靠获得台区的实用无功分散补偿优化配置方案。 |

| Abstract: |
| In order to quickly and accurately gain the reactive power compensation scheme, evaluate the benefits of compensation scheme in low-voltage network more conveniently, and help power grid operator and manager to determine the most economical and suitable reactive power compensation scheme, a reactive power compensation and benefit evaluation system of low-voltage network is developed, which uses the Access relational database management system and Visual Basic 6.0 development tools. This system provides the intuitional and friendly interface, various power flow calculation methods and optimal reactive power compensation calculation methods of low-voltage distribution network, as well as the cost and benefit evaluation calculation of different reactive power compensation schemes. In addition, intuitionistic graphical interfaces is provided for grid operator inputting the information of new program low-voltage distribution network, and calculating the distributed reactive compensation optimal allocation scheme of the low-voltage distribution network. This system has been applied to practical low-voltage distribution networks in Nansha district of Guangzhou city, and it shows that this system is convenient to use and can reliably gain the practical distributed reactive compensation optimal allocation scheme of the low-voltage distribution network. |
