Abstract

The invention relates to an SVG fault analysis system, which includes a building block for modeling and forming a power supply model, and the power supply model includes power supply components and logical relationships between components; a monitoring module for monitoring the power supply system The power supply components are monitored in real time to obtain the component parameters of the power supply system; the transmission module is used to transmit the component parameters of the power supply system to the building module; the central control module is used to obtain the actual value of the component parameters in each monitoring period The relationship with the preset standard value adjusts the transmission speed of the parameters of the components, and protects each component by time according to the logical relationship between the components. Determine the logical relationship between components and components in the power supply network by constructing a power supply model, compare the real-time monitored parameter data with the preset standard parameter data, and determine the urgency of the parameter data transmission according to the comparison results In order to enable the central control module to build protection measures for components in a timely manner after receiving the parameter data, and realize the protection of the power supply system by time, so as to reduce the probability of damage to the power supply system.

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...
