The unified power flow controller (UPFC) has been proved to be an effective means for regulating voltage and power flow in modern power systems. Optimizing its location becomes a key point in the practical implementation stage. Approaches at present haven′t take the influence of transmission line congestion into account.This paper introduces the concept of line active power flow performance index, compares real-time power flow with its ratings and uses overload severity as the guideline, thus, optimizes location of UPFC by means of index sensitivities with respect to control parameters of UPFC. Case studies show that this approach is concise and feasible.

在现代电力系统中,统一潮流控制器(UPFC)是调节电压和潮流的有效手段。在实际项目执行阶段UP FC的安装地点问题显得尤为重要。目前存在的布点方案没有考虑输电线路阻塞对布点结果的影响。该文引入线路有功潮流性能指数的概念,考虑了线路实际潮流与额定值的相对大小关系,采用有功过负荷的严重程度作为指标,根据UPFC参数对其产生影响的灵敏度因子大小来确定最佳安装地点。经算例验证,该方法简便快速,准确可行。

Power system calculation data base (PDSB) is used in the off-line electric power calculation data base system. The data base system stores device parameters into 2D free tables in terms of device types, and realizes data exchange with SCADA based on PDSB. A real-time power flow files creating system is developed. With real-time data about bus loads, generators, current electric power network structure and so on got from SCADA, the PDSB data-based system can...

Power system calculation data base (PDSB) is used in the off-line electric power calculation data base system. The data base system stores device parameters into 2D free tables in terms of device types, and realizes data exchange with SCADA based on PDSB. A real-time power flow files creating system is developed. With real-time data about bus loads, generators, current electric power network structure and so on got from SCADA, the PDSB data-based system can create power flow files in some format quickly and exactly.The created files are used as source files to analyze the stability of the electric power system.

该数据库是以二维自由表为基本存放数据的形式,将电力系统的设备参数按设备类型存入表中,并在PDSB的基础上实现与SCADA数据交换的功能。开发了实时生成潮流文件的系统,该系统基于PDSB的数据,结合SCADA实时得到母线负荷、发电、实际运行的网络结构等数据,快速准确地生成某种格式的潮流文件,作为系统稳定分析的源文件。
