摘    要:中国的无功电压问题日益突出,研发电力系统全局电压优化控制系统已经成为当务之急。文中借鉴了法国等欧洲国家的成功经验,面向国内网、省调,以现有的能量管理系统为基础,设计实用的全局电压优化控制系统。提出了“软分区”的3级电压控制的新思路,无须建设“硬”区域电压控制器,而是在控制中心建设“软”二级控制和“软”三级控制,以软件方式来实现控制的时空解耦,较好地解决了多目标控制问题。探讨了控制系统在实现中的一些重要问题。这种新的控制模式非常适合发展中的中国电力系统,即将在江苏省电网得到应用。

关 键 词:电力系统  全局电压优化控制系统  软分区  系统设计  电力调度自动化系统

Abstract:The voltage quality of power grid becomes more and more serious in China. It's urgent to develop global optimal voltage control system for energy control centers. In this paper, adopting the successful experiences of several power companies in Europe (such as EDF, RWE and etc), the design is done for practical global optimal voltage control system, which is based on energy management system and more fit for implementation in China. In the paper, a new idea of three hierarchical control structure based on soft identification of secondary control zones is presented. In the new structure, no hard secondary controller is needed, and both the secondary and tertiary controllers are implemented by software in the same control center. With different time constants and control zone division, the voltage control is decoupled, and the multi-objectives about economy, quality and security are coordinated here. Some important problems about implementation are discussed. Such new control structure will be applied to the power system of Jiangsu Province in China. This project is supported by National Key Basic Research Special Fund of China (No. G1998020322) and National Natural Science Foundation of China (No. 50107005).
Keywords:voltage control  optimization  hierarchical control  information theory  power systems
