电力系统安全稳定控制装置的测试一直是制造厂商和用户面对的关键问题。文中分析了通用测试仪器功能要求,介绍了一种通用测试仪器的总体结构、软硬件特点及为适应不同型号安全稳定控制装置而进行的通用性设计特点,最后引用检测报告分析了该测试仪器的输出精度。详细介绍了再现模拟量波形的软硬件方法和相关公式,该公式不仅可以再现标准正弦波,也可反映各种故障波形。
Testing of power system security and stability control devices has always been a key issue for manufacturers and users alike. This paper analyzes the functional requirements of universal testing instruments, introduces the general structure, hardware and software features of a universal testing instrument and the universal design features to adapt to different types of safety and stability control devices. Finally, the testing report is analyzed to analyze the performance of the testing instruments Output precision. The software and hardware methods and related formulas for reproducing the analog waveform are introduced in detail. The formula can not only reproduce the standard sine wave but also reflect various fault waveforms.
