 摘 要
 随着科学技术和国民经济的快速发展，电能质量越来越显示其重要性，也对电力系统运行的可靠性及自动化程度提出了更高的要求。用计算机来实时有效地监视和控制电力设备运行状况，监测电力系统的运行工况已成为一种趋势。
 电力参数监测仪是一种测量电网中电压、电流、功率、谐波等参数的仪器，它在电力系统中起着非常重要的作用。这次毕业设计的主要任务是使用VC++语言，设计一个电力参数监测仪上位机界面。此界面显示包括A相、B相、C相电压、电流、功率因数、有功功率、无功功率、视在功率数据，电压谐波数据，电流谐波数据，使其能有效、及时的监控工作现场状况，还能显示时钟。
 在此次毕业设计过程当中，首先结合指导老师的要求（使用VC++语言编程），查找这方面资料，并且熟悉VC++的编程软件，学习C++语言。最后在基于对话框的MFC应用程序上编程，添加代码，美化界面，添加MSComm串口通信控件，对接收的数据进行处理，并输出到界面。

Abstract
Along with the fast development of science technique and the national economy, electric power quality more and more shows its importance, put forward higher request to the credibility and automation degree of the electric power system movement. Using the computer to monitor and control the operation of electrical equipment and the power system has become a trend.
 Power parameters monitor is a measure of the power voltage, current, power, harmonics, and other parameters of the apparatus, its power system plays a very important role. The graduation project's main task is to use the VC++ language, the design parameters of a power monitor PC interface. This interface shows the data of the A phase, B phase, C phase voltage, current, power factor, active power, reactive power, apparent power, harmonic voltage and harmonic current, to enable them to effectively and timely monitoring Working conditions at the scene, and shows the clock.
 In the graduation design process, combining to the requirements of guide teacher's request (using VC++ programming language), first find information and recognize the VC++ programming software, learn C++ language. Finally, program on the application based on the MFC dialog, add the code, landscape interface, add serial communication control (MSComm), process the reception of data then output to interface.
