摘　　要：随着电力电子技术的快速发展,各种非线性设备被大量应用到生产实践当中,这些非线性和冲击性的负荷,严重影响着变电站的安全经济运行,导致电能污染日趋严重。因此,对电能质量进行在线监测,可以为改善电能质量、提出治理方案以及确定治理装置提供科学的依据,具有十分重要的意义。从电力监测的实际要求出发,设计了基于以太网的电能质量综合监测系统,介绍了系统的工作原理和各组成模块的设计,并通过实验验证了系统的可行性,对于地域跨越大的电网的远程监测提供了一种新思路。With the rapid development of power electronic technology,various nonlinear devices are widely used in production practice.The nonlinear load and shock resistance,seriously affect the safe and economic operation of transformer substation,which leads to power pollution becomes more serious.Therefore,the online monitoring can provide scientific basis for the improvement of power quality,proposing of solutions and determination of the treatment device,which has the vital significance.Based on the actual requirements of power monitoring,the power quality monitoring system based on Ethernet was designed.The working principle of the system and the design of the building blocks were described and the feasibility of the system was proved by experiment.The results show that the system provides a new method for the remote monitoring across the network for regional.
