Research of distributed photovoltaic power supply access simultaneous power quality monitoring system

Using the technology of WAN Sync measurement based the GPS, this paper proposes a simultaneous power quality monitoring system applying to the characteristic of the photovoltaic in order to solve the power quality problem causing by the technology of distributed solar energy power accessing to the power distribution network. The system can be used to get the simultaneous monitoring data of the photovoltaic power accessing point. Indicators of the power quality can be analyzed by the central visual software platform. The result of the analysis is the basis for the problem of the power quality.
