Electromagnetic Processes during Crash of a Switch in a Frequency-Starting Circuit of Reversible Motor Generators of Hydroelectric Pumped-Storage Power Plants

摘要

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.
