Description

technical field [0001] The embodiment of the present invention relates to the technical field of model testing, and in particular to a STATCOM transient response analysis system and method based on fault recording files. Background technique [0002] The 100MVA level dynamic reactive power compensation device (STATCOM) refers to a device that uses self-commutated power semiconductor bridge converters to perform dynamic reactive power compensation. The power supply is safe and acts as a "voltage stabilizer" for the power grid. Therefore, the transient response effect of the STATCOM device when stabilizing the grid voltage is one of the main assessment indicators for the operation and maintenance of the STATCOM device. [0003] When the grid voltage drops or the sudden change of voltage fluctuation starts, the STATCOM device will start the transient response process to compensate the reactive power of the grid. [0004] According to the design requirements, after meeting the...
