Development of a program code for calculating the flow paths of steam turbines with long blades [PDF]
Paper is devoted to the development of software code for calculating low-pressure cylinders of steam turbines. The program code divides the steam turbine compartment with a long blades into separate stages, and also calculates these stages by sections in

Application of small‐signal analysis tools for power‐electronic‐dominated systems. Abstract The stability, operation, and control of power networks have been challenged due to the increased penetration of power electronic converters. New instability phenomena have appeared due to the interaction of the power converter controllers with other power ...

Simple prediction method of unstable fluid force in turbine blade row of steam turbine
Unstable fluid force may be induced by rotor blade eccentricity in turbo machinery such as steam turbines. To develop a prediction method for unstable fluid force in turbine blade rows, we calculated the fluid force by using computational fluid dynamics (

A dynamic equivalent aggregation method is developed for wind turbine systems with full‐scale power converters to improve the electromagnetic transient simulation speed. A precision equivalence for the collecting network considering is introduced. A Louvain K‐means clustering algorithm is adopted to determine the optimal clustering result.

Considering the importance of the subject, here, a PV hybrid system with a concentrator and an ORC is evaluated from a technical and economic point of view. First, system modelling methods and relationships governing system components are examined. In this regard, the first and second laws of thermodynamics are very important. Constants and assumptions
