Project summary

It has been planned to reconstruct 39 destroyed Midget Power Plants (MPP) with total output 22 MW on mountain rivers and to build 12 new MPP with output not less than 10 MW on rivers and water storages according to the Program “Development of small water-power engineering in Kyrgyzstan” by 2010.

MPP operating experience, stored within 40-70th years, indicates that hydraulic structures, especially water intake facilities are the most vulnerable parts of hydropower units. These constructions are designed without taking major diurnal variation of river flow into consideration because this variation is not studied enough. Head works used to be built for such constructions often were destroyed by flood, as well as persion channels were blocked by sediment. Operation of water intake facilities in winter, i.e. at temperatures under 0oC, is especially difficult. It has been planned to reconstruct MPPs on the following rivers: Issyk-Ata, Sokuluk – in Chui oblast, Kochkor and reservoir Orto-Tokoi – in Naryn oblast, Tup and Juuku – in Issyk-Kul oblast, within the next few years. For this purpose monitoring of river runoff and sediment runoff will be required as well as modelling of water intake process into persion.

Problem to stabilize the water flow arises when taking water from chutes with unsteady-state water flow mountain and foot mountain areas. This stabilized water flow can be used in for energy needs.

The embankment dams on fractured bedrock bases located in a seismic zone undergo shearings during earthquake. Such shearings can become a reason of a strain or destruction.

There is a problem in adapting of flow capacity of head to build-up part of open shore flood-discharge outlets of embankment dams during use of them. Saving stability of a high-speed flow on rapids is problem too.

The authors of the project - scientists and military specialists have wide experience of researches in given area. Project manager has received 15 inculcation statements of new patent hydraulic structures for the projects and real objects in Kyrgyzstan and Kazakhstan.

In the elaboration of the project KR-1130 the authors plan to use aviable international technologies in the field Hydraulic structures for small hydropower engineering. Particularly, while researching the task of monitoring of river runoff and research of river bed evolution, the participants are planning to use the experience of the collaborators of the project from the Italian Universities of Trento and L’Akila, company HR Wallingford (United Kingdom) and researchers from the University of Berne (Switzerland). The experience of the physical modeling of the water intake facilities of the Munchen Technical University will be used, in particular, for the specific hydraulic method of fish protection. Modern technologies used in MPP of Norway, Switzerland and in the Hudraulic Structure of USA, Japan, Germany, Kazahstan and Kyrgyzstan will be also considered for this project.

The realization of this project will give a probability to improve the methods of analysis, designing and construction of hydraulic structures for MPP in mountain and foot mountain areas of Kyrgyzstan.

Hydraulic structures that have been constructed earlier or are designing now in mountain and foot mountain areas are harmful for ecology and biovariety. Their constructions are calculated at full 100 % persion river flow in low water-level period and are not provided with fish migration ways through hydraulic units and have no fish protection structures.

Hydraulic structures and methods of monitoring, analysis and designing of power units that will be will be developed in this project, will be useful in the Central Asia countries, in China and in other regions with mountainous relief.

Proposed project belongs to applied research category in the field of hydraulic engineering for needs of power.

Realization of the project will provide the solution of the following tasks:

  • Monitoring of river and sediment runoff forming of mountain rivers;
  • Hydraulic modelling of water intake facilities from mountain rivers for MPP;
  • Laboratory and full-scale research of water intake facilities from chutes in mountain and foot mountain areas for Micro Power Plants;
  • Influence of tectonic breaks in embankment dam’s base on dam stability modelling;
  • Theoretical and experimental research of open flood-discharge outlets;

During realization of the project it is supposed to use river flow monitoring, physical and mathematical modelling methods.

The group of military scientists is the core of the project, they are specialists in the sphere of guidance systems and assessment of weapons of mass destruction action.

Within the frameworks of the project scientists and specialists involved in weapon designing will get an opportunity to aim their skills at peaceful targets, by means of taking part in designing water intake automation systems and control systems perfection, in research of water intake structure stability and designing instruments and equipment for conducting hydraulic research.

It is provided to collaborate in the following:

  • to share scientific information during realization of the project;
  • to give reviews or comments on technical reports;
  • to give data about equipment and technologies for experimental research;
  • to evaluate technology that will be developed during realization of the project;
  • to participate in technical control of the project;
  • to conduct joint seminars and symposiums, to publish results of the project research;
  • to organize trainings for the participants of this project in the area of hydrology, hydraulics and hydrotechnics.
