统一潮流控制器模型电量测试系统

An Electric Quantity Testing System of Unified Power Flow Controller Model

为更深入了解统一潮流控制器性能,以一台10 kVA模型为对象开发一套电量测试系统。该测试系统的组建采用虚拟仪器的概念,系统硬件为模块化设计,由传感器、信号调理电路、数据采集卡和通用个人计算机组成,系统应用软件开发环境选用面向测控领域的软件开发平台LabWindows/CVI。该电量测试系统拥有友好、易操作的用户界面,且具有较强的通用性。最后通过图形比较从几种常用的小波基中找出两种比较适合电信号分析的小波基。

In order to deeply study the performance of unified power flow controller, an electric signal testing system is developed based on a 10 kVA experimental device. The virtual instrument technology is adopted to build the testing system. The hardware uses the modularization design, which consists of sensors, signal regulating circuits, data collecting card and personaI computer. The LabWindows/CVI serving the measure and control fields is adopted to be the software developed platform of the system. The testing system is provided with friendly and operated-easily consumer interface, furthermore, it has stronger universality. Moreover, through comparing the figures, two wavelet functions that are suitable for electric signal analysis are selected from several typical wavelet functions.
