| Summary: | Nowadays, tidal stream energy has become a viable choice of generating electricity in many countries. It is because the tidal stream energy are predictable and a reliable source of generating electricity as it is depend on the gravitational attraction between the Earth, the Sun and the Moon. The venture into this clean energy production is a practical choice. It is in enhancing energy security in Malaysia due to nature of the
tidal stream technology require less construction and environmental effects. In this thesis, the aim is to design a low current tidal stream turbine for Sarawak tidal stream application. The low current tidal stream turbine based on the hybrid turbine of four blades Darrieus turbine (lift type), and 2 paddles of Savonius turbine (drag type) as the startup turbine. The hybrid turbine of 1 m height has a better starting torque and
power output compare to any tidal stream turbine that operate by a single turbine in a low current tidal stream condition. The details designing of the turbine are discussed in this thesis by using Off Kuala Igan tidal stream data to design the suitable cut-in speed for the turbine in low tidal current condition. One unit of the turbine is able to produce daily energy of about 3.6 KWh (3669Wh) at low tidal stream speed of 1 m/s.
The arraying of the tidal turbines to few units according to the available space without arising conflict with other sea users is possible in order to increase the power extraction and by deploying the turbine at higher tidal stream speed. The electric generation can be stand-alone power system for more decentralized future power
system or the power system also can be synchronized with grid by exporting the surplus energy back to grid. |
