DETERMINATION OF THE TEMPERATURE FIELD DISTRIBUTION IN THE WINDING RODS OF THE STATOR OF TURBOGENERATORS OF TYPE TVV FOR PURPOSES OF CONTROL AND DIAGNOSTICS

Turbogenerators were and remain the most unreliable element at nuclear power plants in Ukraine. The dangerous disturbances operation of turbogenerators TVV type is complete or partial blockage hollow conductors stator winding. systems operational control technical diagnostics today, a number cases, cannot cope with identification these phenomena. complex application adequate mathematical models, indications standard thermal system new diagnostic features give opportunity sufficient accuracy for practical purposes to detect blockages windings turbogenerators. aim work develop program calculating three-dimensional temperature field rods winding turbogenerator TVV-1000-2U3 type, taking into account core, carry out test calculation compare experimental calculated data. problem solved help finite difference method using integro-interpolation method.
