Evaluation and measures to increase performance coefficient of hydrokinetic turbines

In this study was presented the valid equations for energy conversion system from water currents analogous to wind power system. Hydrokinetic technology may be divided into two categories such as horizontal and vertical system. Application of the systems is possible to marine, and river currents. Each system has different performance coefficient. Hydrokinetic energy conversion systems shows lower power coefficient. The existing measures with the purpose of increasing of performance coefficient have been presented. Additional suggestions have been put forward. Future perspectives for application improvement and working fields of different kind have been given.
