In view of the requirements of diversity,real-time and accuracy of operation data monitoring in the transition from traditional distribution network to intelligent distribution network,as well as the current situation of poor real-time data collection and single function of existing distribution network clata monitoring devices,this paper proposes a design scheme of operation data monitoring device based on synchronous vector,including current monitoring based on GPS clock synchronization Measurement module,running impedance monitoring module and harmonic monitoring module based on synchronous vector can realize the real-time and accurate monitoring function of current,impedance,loss and harmonic during the operation of distribution network.At the same time,a synchronous vector based distribution network operation data monitoring device is designed,which can solve the problem of delay caused by remote data transmission in the distribution network,system performance degradation caused by low accuracy of harmonic measurement,and the problem of low positioning speed and accuracy of singlet-phase ground fault.It can provide a better targeted effect for the transition from traditional distribution network to intelligent distribution network research and development of data precise monitoring equipment.
