基于虚拟仪器和数据库技术的电能质量监测系统设计

摘要

According to the virtual instrument technology, the database technology and the national standard, a power quality monitoring system with a distributed structure is proposed. In this system, with the model of client and server,the data of the important circuit is collected and processed, so as to obtain advantages and disadvantages of the state of all power quality. The client is mainly used to collect data, and the server is mainly used to process the collected data for completing the waveform display, printing statements and other functions. Based on the database technology, the client and the server complete the data exchange by the form of fiber ethernet. It achieves good real - time, high reliability, low development costs and so on.%根据电能质量的国家标准,提出了一种以虚拟仪器技术和数据库技术为基础的,具有分布式结构的电能质量监测系统.该系统以测控终端客户机和后台管理服务器的模式,对重要回路进行数据采集和处理,得出各项电能质量的优劣状况.客户机主要用来采集数据,服务器对采集的数据进行处理完成波形显示、报表打印等功能,两者之间以光纤以太网的形式完成数据交换,具有良好的实时性、较高的可靠性和开发成本低等特点.
