However, with the rapid development of the power grid, the increase in the capacity of the transmission lines and the installation of new equipment means the short-circuit current has grown, which has serious impacts on the stability and safety of the power grid. Therefore, it is necessary to study short-circuit current limitation measures in the Urumqi 220kV power grid.2 Research ObjectivesThe objective of this research is to investigate the short-circuit current limitation measures for the Urumqi 220kV power grid. This study aims to:- Analyze the short-circuit current level in the power grid, and calculate the short-circuit current and fault clearing time of the entire power grid.- Evaluate the stability and safety of the Urumqi 220kV power grid during a short-circuit fault.- Study and compare different short-circuit current limitation measures for the Urumqi 220kV power grid, such as series compensation, grounding resistance reduction, and shunt compensation technology.- Determine the optimal short-circuit current limitation measures for the Urumqi 220kV power grid according to technical and economic analysis.3 Research MethodsThis research will adopt the following methods:- Collect and analyze the relevant data of the Urumqi 220kV power grid, including the configuration and operating 精品文档---下载后可任意编辑conditions of the power grid, short-circuit current parameters, and historical fault records.- Carry out simulation analysis ...
