NOVELTY - The generator (1) has a modular arrangement converting hydraulic energy into electrical energy, where the arrangement is made of integrated modules, and the modules are an inlet module (2), a generator module (3), a distributor module (4) and an outlet module (5) interconnected to each other by external flanges provided in the module and through an inlet bearing unit and an outlet bearing unit placed throughout a longitudinal shaft aimed at transmitting a hydraulic turbine torque upstream to a generator rotor. An additional conversion module is seldom provided.    USE - Turbo-generator for generating electrical energy from water-flow.    ADVANTAGE - The generator assembles a hydraulic turbine by modules to allow a high level of standardization in an equipment, a significant reduction of installation costs in a hydro-electrical power plant of a type as a small central hydro-electrical plant, mini central hydro-electrical plant, micro central hydro-electrical plant and peak central hydro-electrical plant when the turbo-generator can be directly installed in a water storage dam as a single set/as a modules-made set requiring a minimum of additional civil construction works. The generator allows Kaplan/propeller type hydraulic turbine that is directly connected to the permanent magnets synchronous generator rotor by a shaft made into a single piece/divided into sections not requiring speed reducing/speed increasing units such as reduction gears/conveyor/friction transmission. The generator allows an optimized design of turbine/generator set by using a number of pole peers suitable for application in such a way to obtain the best output for the turbine electrical generator jointly, thus eliminating the use of gears/conveyors and pulleys for coupling units, and ensures a high output to hydro-generator. The arrangement for the hydraulic turbine allows use of the turbine for hydro-kinetics and for hydro-generators to be used with waterfalls with around 30 meters high when generators in a series are used in the same flow stream, the same arrangement can be used with waterfalls higher than 30 meters high. The arrangement is found in which a variation can be used in the pole numbers/a variation in the permanent magnets synchronous generators number within the same module. The arrangement allows an operation without varying direction of water flow as the water flow can run horizontally in other inclination, so that the set architecture avoids the use of a heat-sink.
