Abstract
The article describes the most common schematic diagrams of electro-hydraulic control systems for steam turbines. The main advantages and disadvantages of these schemes are given. It is noted that for the modernization of steam turbines in operation, the cheapest and most effective is the choice of electro-hydraulic systems built on the basis of electromechanical converters. Electromechanical converters are subject to repair in a power plant, provide the required resource with a high level of reliability, minimal modifications of the hydraulic part are required, steam distribution can be saved
