Functioning the hydroelectric pumped storage power plant in condenser regime for network stabilization is a common practice. During this operation, hydroelectric machines (doubly fed synchronous machine and doubly fed asynchronous machine) are influenced by various power quality perturbations causing failure to the system. This paper investigates the electro-thermomechanical effects on hydroelectric...
Enhancing the reliability of pumped storage hydroelectric system is mandatory for building the stable network. This paper experimentally analyses the electrical and mechanical effects of voltage unbalance on doubly fed synchronous (fixed speed) machine and doubly fed asynchronous (variable speed) machine operating under motoring mode. The input electrical quantities such as stator current, rotor current,...
