【摘要】 随着国民经济和科学技术的发展,现代电网与负荷构成出现新的变化趋势,由此带来的电能质量问题越来越引起电力部门和电力用户的高度重视。一方面,扰动负荷(如非线性、冲击性或不对称负荷)接入电力系统或其他扰动源(系统短路故障)存在使电网出现诸如波形畸变、电压闪变、电压凹陷等较为严重的电能质量问题,不但影响公用电网的安全运行,还对各种电力用户的用电过程造成直接与间接的危害;另一方面,人们所使用的精密仪器和复杂电子设备也要求高质量和高可靠性的电能供应,因此很有必要研制电能质量监测装置。 论文第一章分析了电能质量监测装置研制的意义,电能质量指标和国家标准,国内外电能质量监测装置的研制现状以及不足。第二章针对电能质量监测的要求,结合计算机、通信、数字信号处理等技术的进步,提出了电能质量监测装置的开发方案,并分析了开发电能质量监测装置的硬件和操作系统选型,然后详细分析了电能质量监测装置的各个模块。第三章从认知心理学和人机工程学等角度分析人机界面设计中应注意的问题和遵守的原则,并将上述原则运用到电能质量监测装置人机界面设计中,力求使其人机界面标准化、规范化和人性化,以便于用户学习与使用。在完成人机界面的设计后,将嵌入GUI技术应用到人机界面的开发中。第四章总结整个论文工作,说明研究需要进一步深入的地方。更多还原

【Abstract】 Along with the development of national economy and technology, the modern electrical network and the load constitution have come out new change tendency, which causes many power quality problems. These problems get more and more focus by the electric power department and users. On one hand, the disturbing load (eg: nonlinearity, impact, or asymmetric load) or other disturbing sources (eg: system short-circuits breakdown)causes the electrical network to appear serious power quality problems such as wave distortion, voltage flicker and voltage sag .These problems not only affect the safe operation of the public electrical network, but also cause direct or indirect harm to the instruments which are in use. On the other hand, the precision instruments and the complex electronic installations also require high level and reliable electrical energy supply. Therefore the power quality monitor is highly needed for electric users. The development of power quality monitor is of great value.In chapter 1, guide lines and national standards for power quality, the development significance, the present state as well as insufficiency of power quality monitor are introduced. In chapter 2,with the development of computer, communication, digital signal process and so on,a development plan of power quality monitor is introduced. The type of hardware and the type of operating system are also chosen. Then the functions and structure of power quality monitor are analyzed in detail. In chapter 3,at first, the problems and principles in man-machine interface design are analyzed, then the principles are used in man-machine interface design for power quality monitor to make its man-machine interface be standardization and humanization, so that users can use it in comfort. After completing its man-manchine interface design, the technique of embedded graphic user interface is applied for the development of its man-machine interface. In chapter 4 the entire paper work is summarized, and the points for further research are pointed out.更多还原
