Abstract

The invention relates to an SVG fault analysis system, and the system comprises a construction module which is used for modeling to form a power supply model, wherein the power supply model comprises power supply components and the logic relation between the components; a monitoring module used for monitoring power supply components in the power supply system in real time and acquiring component parameters of the power supply system; a transmission module used for transmitting component parameters of the power supply system to the construction module; and a central control module used for adjusting the transmission speed of the component parameters according to the relationship between the actual values of the component parameters in the monitoring time periods and the preset standard values, and performing time-phased protection on the components according to the logic relationship among the components. Components in a power supply network and a logic relation between the components are determined by constructing a power supply model, parameter data monitored in real time are compared with preset standard parameter data, and urgency of parameter data transmission is determined according to a comparison result. Therefore, after the central control module receives the parameter data, protection measures for the components are established in time, time-phased protection of the power supply system is realized, and the probability of damage to the power supply system is reduced.

Description

technical field [0001] The invention relates to the technical field of circuit fault analysis, in particular to an SVG fault analysis system. Background technique [0002] With the increasing integration of electronic circuits and wider operating frequency band, some unexpected electromagnetic energy often appears during normal operation, and the problem of electromagnetic interference becomes very complicated. Electromagnetic compatibility has gradually become a measure of the overall quality of electronic and electrical products. An important indicator of performance. Static var generator (SVG) is widely used in wind farms, photovoltaic power plants and other places. If its power module is subjected to electromagnetic interference, a DC overvoltage fault may occur, which will cause the SVG to shut down. The static var generating device is arranged between the load and the grid, in order to ensure the stability of the power supply in the grid during the process of supplyin...
