摘要
随着电力电子与信息技术在社会各个领域的渗透应用,一些新型电力负荷对电能质量的要求不断提高,电能质量已成为电力企业和用户共同关心的课题。但在现实中,由于大量非线性设备的使用,造成了电能的严重污染,极大地影响了电力系统的安全运行。因此,以计算机技术、数据库技术、网络通信技术为依托,结合电网中各个监测点构建成一个完整的电能质量监测网络系统,从而实现对电网各项电能质量指标的在线监测和统计分析,就显得尤为重要。根据电能质量的国家标准,综合考虑成本和性能因素,设计出了以AT89S51单片机为核心的在线监测系统,给出了该系统的硬件和软件设计。
Wrlh the applications of power electronics and information technology in all social fields, the requirements of some new power equipments for electrical energy quality are increasing, so power quality has become the common concem of the electric power enterprises and users. However, in reality, due to the use of the large number of nonlinear devices, the electric energy is seriously polluted, which has great influence on the safe operation of power system. Therefore, it is more important to realize the power quality online monitoring and statistical analysis based on computer technology, database technology, and network communication technology, combined with the power of each monitoring point to conslitute a complete power quality monitoring network system. According to the national standards of power quality, the comprehensive consideration of the cost and performance factors, the on-line monitoring system with AT89S51 microcontroller as the core was designed, and its hardware and software design was proposed.
