What is Steam turbine T S I system?
The TSI system is Turbine Supervisory Instrumentation system, consists of multiple instruments, including speed sensors, speed monitors and so on. The system continuously monitors the steam turbines of all important parameters, such as: rotational speed, overspeed protection, eccentricity, shaft vibration, cover vibration, axial displacement, differential expansion, and thermal expansion. The system helps to improve the availability of steam turbine unit.
Steps of synchronizing steam turbine generator?
1. Turn Electronic Governor Switch on. 2. Open casing drain valves 3. Check bearing oil levels 4. Reset Over-speed Trip 5. Put bearing cooling water on 6. Crack exhaust (outlet steam header) and adjust drain valves accordingly 7. When warm crack inlet steam valve allowing turbine to run at 10rpm 8. Check bearing oil rings 9. Look for carbine seal run offs 10. When turbine is warm fully open inlet steam valve and allow governor to take control to 2200rpm 11. Use speed knob to raise speed to 3600rpm 12. Turn Field Excitation Switch on 13. Check incoming and grid voltages and match turbine generator excitation to grids voltage using the field excitation rheostat. 14. Use speed knob to reach 60hz 15. Turn on synchronization switch to the synchroscope 16. Adjust turbine speed to adjust the phase angle/frequency to a steady slow clockwise rotation on the synchroscope. 17. Close generator breaker at the 5min to 12'oclock position on the synchroscope. 18.Turn of the synchronization switch to the synchroscope. The turbine is now synchronized to the 60Hz power grid.

Device to increase speed of spinning shaft?
To increase the speed of a spinning shaft, you can use various devices and mechanisms based on the specific requirements and constraints of your application. Here are a few methods and devices that can help increase the speed of a spinning shaft: **Gearbox:** A gearbox is a common device used to increase or decrease the speed of a shaft. By using different gear ratios, you can achieve the desired increase in speed. A smaller gear driving a larger gear will result in higher rotational speed at the output shaft. **Pulley System:** A pulley system, often used with belts or ropes, can increase shaft speed. By using pulleys of different sizes and diameters, you can achieve speed multiplication. A smaller pulley driving a larger pulley will result in higher speed at the driven shaft. **Turbine or Impeller:** In fluid-based systems, a turbine or impeller can be used to increase rotational speed. As a fluid (liquid or gas) passes through the turbine or impeller, it imparts rotational energy to the shaft, increasing its speed. **Centrifugal Clutch:** In some applications, a centrifugal clutch can increase speed. This type of clutch engages as the shaft's rotational speed increases, transmitting power to a higher-speed output shaft. **Variable Frequency Drive (VFD):** In electric motor applications, a VFD can be used to control the speed of an AC motor. By adjusting the frequency of the input power, the motor's speed can be increased. **Turbocharger or Supercharger:** In internal combustion engines, a turbocharger or supercharger increases the speed and efficiency of the engine by compressing air into the combustion chambers, resulting in increased power output. **Transmission System:** In vehicles, transmission systems with different gear ratios can be used to achieve higher speeds by changing the gear ratio between the engine and the wheels. **Hydraulic Transmission:** Hydraulic transmission systems can use pumps, motors, and valves to increase speed by controlling fluid flow. **Cycloidal Drive:** A cycloidal drive uses a set of cams to produce a high-speed output from a lower-speed input. It's important to consider the mechanical limitations, efficiency, torque requirements, and safety considerations when selecting a device or mechanism to increase the speed of a spinning shaft. Consulting with engineers or professionals who specialize in the specific field of your application can help you choose the most appropriate and efficient solution for your needs.
Is high speed balancing required for a steam turbine which has been idle for 15 years?
No.
What is trimming a turbine engine?
The fuel control is adjusted to set idle and maximum speed.
Which device controls the speed of the turbine shaft?
The device which control the speed of Turbine is Governor. The Governing system sense the speed of shaft & regulate the Fuel/ Motive fluid flow to the Turbine to maintain the set shaft speed.
What is Runaway Speed of hydraulic Turbine and how it is calculated?
The runaway speed of a water turbine is its speed at full flow, and no shaft load. The turbine will be designed to survive the mechanical forces of this speed. The manufacturer will supply the runaway speed rating.
What is critical speed of turbine?
SPEED OF TURBINE IS DEPEND ON THE WATER PRESSUR(7BAR)
In a wind turbine - does increasing the blade length or decreasing the blade length increases the speed of the turbine?
Decreasing the blade length will increase the rotation speed, and thus the turbine speed ( for constant wind speed ).
Why is the runaway speed of a hydraulic turbine always kept twice its normal speed?
The runaway speed of a hydraulic turbine is the speed at which the turbine coupled to the generator runs at the maximum possible speed due to loss of load and this happens until the shut off valves completely closes the discharge from the penstock. the runaway speed of the turbine is determined by the turbine designer and is influenced by the maximum discharge of water from the penstock, the combined inertia of the turbine runner and the generator and the flywheel. this factor can vary from 1.5 up to 3 times the nominal speed of the turbine and is determined by the turbine designer considering all the load parameters.
What is the self-sustaining speed of gas turbine?
self sustaining speed is output of a turbine= input into compressor
