Multi-user Software Design Of Generator Rotor Inter Turn Short-circuit Fault Diagnose System

As the basic equipment of generating, synchronous machines play very important role in safety and stability of the whole power system. So developing on-line diagnosis to find fault in turbo-generator timely and effectively has become one of the important methods gradually to ensure the machine operating safely and reliably. Shorted rotor winding is a usual electric fault of synchronous machines. The paper is based on the analysis of fault mechanism of turn-to-turn short circuit of rotor windings in turbo generator. And based on the analysis of the theory and the experiments, Rotor Windings Inter Turn Short-Circuit Fault Diagnose System of Turbine-Generator(RDST) is developed. Further, the new RDST which works on the Web form is designed. It can work online to identify the fault and the severity of the rotor inter turn short circuit which is more convenient and quick in supervising.
