This famous hydroelectric power plant has a complex structure, caused by the placement of capsule units directly into the waterways and the need therefore to have in the design of the at least two conduit limited capacity caused by the use of horizontal capsule units, limited reliability, as well as limited scope, due to the relative ineffectiveness of hydroelectric power plants in lowland rivers with a small flow rate and low flow.

Closest to the technical essence of the present invention is a "Hydroelectric "VOLKOV", including specified in the stream near the shore, is supplied at the input protective gratings oriented at an angle to the direction of flow, the intake duct with the upper inclined, lateral and lower bottom walls, with decreasing flow cross CE and unified work items, in the side wall are covered with the valve hole, which includes the working blade vertical-axis of capsule units, equipped with devices for regulation and stabilization of the number of revolutions of the capsules and placed in the cylindrical housings of the working chambers with a cutout installed removable on moving platforms that move with the help of motors and mechanisms installed in an airtight compartments on reference sites, attached to work items of the conduit (see Russian Federation patent 2140012 C1 IPC 7 F 03 In 13/00, 20.10.1999).

However, the hydropower plant has a limited scope, the inefficiencies caused by its use in streams with relatively low velocity, so as to ensure its efficient operation of the dimensions of the diversion boxes should be large, a relatively small capacity, due to the relatively small intake and consumption, as well as the relative complexity of the structure caused by the presence in the working elements of the conduit guide vanes, dampers, mounted on the ledges, moving in the slots in the bottom walls of the working elements, and pressurized compartments with servo motors and arc and increase hydroelectric power.
