Wind Turbine Generator Condition Monitoring Using Temperature

ambient temperature is high, wind speed is relatively low, and the generator load is low and generator failures are seldom. In winter, the wind speed is high, but the ambient temperature

Steam Turbines: Basics, Types, Selection,

A Steam Turbine is an engine that converts heat energy from pressurized steam into mechanical energy where the steam is expanded in the turbine in multiple stages to generate the required work. Steam turbine engines are used to

Steam Turbines: A Durable and Enduring Necessity

Turbine output and thermodynamic efficiency (directly related to operational costs) both improve with higher steam temperatures and pressures. Many of today''s modern steam turbines drive generator sets of 1,000 MW or

Steam turbine

A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles

Essentials of Steam Turbine Design and Analysis

This process can be followed on an enthalpy-entropy (H-S) diagram, known as a Mollier chart. In the example diagram (), the path from Point 1 to Point 2 represents typical BPST operation at a chemical plant, pulp and paper mill, oil

Wind Turbine Generator Reliability Analysis To Reduce

Wind turbine generator failures are one of the primary reasons for increased operations and maintenance (O&M) costs and generation asset downtime. • Are there any early indicators

High-temperature fatigue behavior of a steam turbine rotor under

This study investigated the high-temperature fatigue behavior of a steam turbine rotor under long-term operation with multiple startup types including one cold, three warm and

Large-scale wind power has its down side — Harvard

For an isolated wind turbine, interactions are not important at all, but once the wind farms are more than five to 10 kilometers deep, these interactions have a major impact on the power density." The researchers

Steam Turbine Deposition, Erosion, and Corrosion

The development of modern, high-efficiency steam turbines has led to an increase in deposition, erosion, and corrosion problems. Close tolerances in the turbines, the use of high-strength steels, and impure steam all contribute to

6 FAQs about [The harm of high wind temperature of steam turbine generator]

Why do steam turbine blades get eroded?

Erosion is particularly problematic for steam turbine blades. Steam turbines operate at higher temperatures and with a more closed gas path compared to centrifugal compressors. Solid particle erosion can occur on steam turbine blades due to the exfoliation of scales from piping during transient conditions.

Are higher steam conditions promising for future development of steam turbine technology?

This paper also deals with further e・orts targeting even higher steam conditions, which are promising for future development of steam turbine technology. Key Words:Steam Turbine, Steam Condition, High Temperature, Thermal E・ツiency

How to improve temperature of steam turbines?

2.2 Material improvement Material development is the most critical technology to achieve temperature improvement of steam turbines. This is because steam turbines do not use complicated cooling technology compared with gas turbines, resulting in primary focus on the development of heat-resistant ma- terial.

What happens if a steam turbine is wet?

As the latter stages of a steam turbine increase in wetness the blades become susceptible to liquid droplet erosion. The damage typically takes the form of removal of material from the blade leading edge. Compressor impeller and hot gas expander blades can also experience erosion damage as well. Creep

Why is steam turbine deposition a problem?

Why do steam turbines have a low efficiency?

Wear of contacting surfaces may result in increases clearances, resulting in reduced efficiency through steam leakage. The HP and IP cylinders in steam turbines operate at high efficiencies and therefore the main opportunity for performance improvement comes from increasing the steam inlet temperature.
