Applicant: JSC «Technopark of Kazakh National University named after Satpayev K.»

Hydroelectric power stations «SAKI»

Description: The novelty and uniqueness of the project lies in the fact that the proposed new types of low-speed generators for wind turbines and small hydroelectric power stations can be made on the basis of existing commercially available induction motors , while on the design, they are simple and practically feasible in production and can be made by enterprises in Kazakhstan. This is achieved by the fact that the rotor reface Mass production engines for the installation of permanent magnets , and the permanent magnets are arranged in a certain order that allows low revs to get an AC voltage

Advantages: Designed a low speed generator can be applied not only in wind turbines and small hydroelectric power stations, but also in the power industry, farms and private farms to supply self-contained power supply, as well as in the low-speed gearless drive.

Current status:Low-speed generator after modernization under hydroelectric power station has been installed at a hydroelectric power station"Saki.Currently JSC "Technopark KazNTU„ and the «Nazarbayev University Research and Innovation System» are signed a contract for prototyping low-speed generator that is compatible with three-phase inverter and system voltage stabilization

Description: novelty and uniqueness of the project lies in the fact that hydroelectric power station "Saki" used supply water to the blade. With the use of jet of water supply to the turbine blades, it will be possible to reveal the loss of water power. Due to the drive, the height of the water level constant, it provides a continuous turnover of the turbine at any season of the year.

Advantages: "Saki" can work without the dam, in world practice it is applied for the first time. Also, this hydroelectric power station can be operated on any mountain rivers. Also, "Saki" is a mobile unit that can be easily transported from place to place.

Current status: Full illumination of the two-storeyed private house of the applicant, owing to stable tension to the inverter via accumulators 26B, after the inverter 220B and with a frequency of 50 Hz, and also stable tension after the inverter 220B and with a frequency of 50 Hz, capacity to 3 kW became results of the last tests of hydroelectric power station which successfully passed in November, 2012 in the settlement Zhandosov, Almaty area.
