Impacts of High-Voltage Asynchronous Motor on Short Circuit Current and Its Substation Design

Taking 110kV substation with lots of high-voltage asynchronous motor loads of certain industrial enterprise as an example, this paper verified the conclusion that there were impacts on short circuit peak current,only near high-voltage asynchronous motors via modeling calculation of certain electrical calculation software.Introduction was made to the impact degree and time of large-sized high-voltage asynchronous motors,the corresponding current limit measures in substation design and the selection of electrical equipment and cautions at the time of dynamic thermal stability rectification for engineering and technical personnel as reference.
