The Power Quality Monitoring System Research Based On IEC61850 Series

The electrical railway construction between Zhejiang and Jiangxi, as a nonlinear impactive load, will badly pollute the power quality of the electric power system, So we should set up a relevant power quality monitoring system in order to maintain the safe and stable run of the power system and keep a stated power quality standard. As the IEC61850 standards use object-oriented design idea and layered separate structure and has the good characteristics of opening and mutual operation,this system is designed and realized according to the IEC61850 standards.the core of the whole system includes server,client, protocol exchange unit ,power quality monitoring model and its modeling tool.This paper illustrates in detail the process of the power quality modeling , the realization of IED common modeling tool based on IEC61850 standards,the function framework of the whole project and the XML technology that the modeling needs. The power quality monitoring system in Jiangxi province has been validated in the spot and runs well now.
