6 FAQs about [Steam turbine generator stator wind zone partition]
Why do turbine generator stator end windings vibrate?
Turbine generator stator end windings vibrate due to electromagnetic forces generated during normal operation or under fault conditions. In normal operation, electromagnetic vibration of a stator core and the electromagnetic forces created by current flowing in stator bars excite the end windings at twice the power frequency (100 or 120 Hz).
How to measure change in current in a steam turbine generator?
The change in current was measured while increasing the AC voltage to 14.4 kV, which is 1.25 times the phase voltage (11.5 kV), for phases A, B, and C, by separating the neutral point of the steam turbine generator stator winding as shown in Fig. 1.
Do off-line generator stator windings have insulation degradation?
Insulation diagnostic tests are being conducted to evaluate the insulation degradation of off-line generator stator windings.
What factors affect the vibration characteristics of a generator stator end?
Some more complex factors such as preload, damping, electromagnetic, temperature, frame, and rotor can be added to the model, and the influence of multiple factors on the vibration characteristics of the generator stator end can be considered comprehensively.
What are GE steam turbine controls?
Thecornerstone of GE steam tur-bine controls is the SPEEDTRONIC Mark V digi- talcontrol system, nowbeing offered asstandard equipment on all new steam turbine u its. Figure 34. Modularized binecontrols.
Where do windings go in a generator?
windings through full-length subslots andis dis-charged along the length of the rotor body thegenerator. On most designs they are shrunk on to the end of the generator b dy, as shown in through radial slots, machined or punched, in the copper conductors. The hydrogen passes from Figure 26.
