Title    Research and Development of Microgrid Power Quality Detection Platform Based on LabVIEW

Abstract As the energy shortage problem increasingly serious, and traditional energy consumption increased at home and abroad, which lead to deteriorating environmental problem。 These problems make global governments pay great attention to the new energy development and utilization。 Microgrid, as one kind of Distributed generation, is a kind of supply to the traditional power system。 It has a high research value in reliability improvement, security of traditional power supply and reduction of the usage of fossil fuels。

Microgrid power quality detection is not only the guarantee of microgrid power security and reliable power supply, but also the important basis of interconnection with users’ equipment。 This thesis referred the analysis of the microgrid related information from domestic and foreign literatures, combined with the current situation of development of power quality detection and microgrid, designed microgrid power quality detection which is based on the LabVIEW platform and the block diagram。 The platform has realized the power quality of real-time monitoring and data analysis。 On this basis, combining with the national standard to PCC in the microgrid, and each related measurement in IEC standard, completed the microgrid monitoring and analysis on steady-state power quality problems, provide a scientific reference for microgrid detection。
