【 摘 要 】

With the vigorous development of new energy power generation technology, the use of a large number of power electronic components and non-linear loads seriously threatens the power quality of microgrid systems. Therefore, it is necessary to monitor the power quality parameters Therefore, it is necessary to monitor the power quality parameters during its operation in real time so as to maximize the use of energy resources. This article focuses on the overall design of the microgrid power quality monitoring system. In the hardware design part, this paper uses two chips of DSP and FPGA to collect, process and analyze the signals of the power grid. Mainly includes the system overall design idea, the signal conditioning module design, the digital signal processing circuit, the communication port circuit and so on. Based on this, combined with the virtual instrument technology, designed and completed a micro-grid power quality inspection platform based on Labview. This paper also establishes the reactive power compensation scheme of the microgrid TSC system by using Matlab/Simulink software, further improves the power quality and power factor of the operation, and verifies the power quality improvement scheme of the microgrid through simulation.
