Electromagnetic processes during crash of a switch in a frequency-starting circuit of reversible motor generators of hydroelectric pumped-storage power plants

Electromagnetic processes during the crash of an aggregate switch in one section of generating equipment as applied to the frequency-starting circuit of reversible motor generators of the Zagorskaya hydroelectric pumped-storage power plant are investigated. A mathematical model for investigating the emergency process is developed. Recommendations for avoiding an emergency situation during crash of switches are proposed using simulation results.
