6 FAQs about [Steam turbine vibration and generator wind temperature]

What causes vibrations in a steam turbine generator?

Torsional vibrations can be excited in the shaft trains of large steam turbine gen-erators by electrical disturbance torques occurring in the active part of the generator with 1 and 2 times the grid frequency. The torque amplitudes can be high, eg during short-time faults, or remain low over long operating periods.

What happens if a steam turbine vibrates?

In operation, the steam turbine occasionally emits vibrations which indicate a symptom of damage to one of its components. If the turbine vibration is left in a high condition, the unit can trip up to ± 50% so that it is unable to supply electrical energy.

Can temperature fluctuations cause steam turbine vibration?

There are many ways that casing temperature fluctuations can cause steam turbine vibration. Casing problems can cause misalignment in many different ways, mostly related to expansion and contraction due to temperature fluctuations.

What is the steam turbine vibration value standard?

The Steam turbine vibration value standard is PT. SEML uses the ISO 20816-2: 2017 (E) standard as shown in Table 1. Table 1: ISO 20816-2: 2017 (E) Standard 4) The recorded data is analyzed one by one to obtain information when the vibration value changes far from the average when the turbine is running.

What are the most common vibration sources on steam turbines?

Below is an overview of several most common vibration sources on steam turbines. Resonance is probably the most common cause of high and vibration-related failures. Unfortunately, vibration specifications often ignore resonances completely and depend upon the manufacturer for such criteria.

How is vibration monitored on a steam turbine?

Vibration on the turbine is monitored by proximity probes only in the vertical direction at both inboard (IB) and outboard (OB) bearings. High vibration excursions occurred on the steam turbine rotor, and consistently tripped the unit during startup or at rated speed.
