Micro turbine working principle

Micro-turbines are tiny gas turbines that can generate both electricity and heat. They vary in electrical output from around 25 kW to 250 kW. Units of between 250 kW and 500 kW are sometimes called mini-turbines. The two types are designed to be used in large domestic or small commercial environments where they can provide both forms of energy Unrecuperated (or simple cycle) microturbines —In a simple cycle, or unrecuperated, turbine, compressed air is mixed with fuel and burned under constant pressure conditions. The resulting hot gas is allowed to expand through a turbine to perform work As the principle of the gas turbine, a working gas (air) is compressed by a compressor and heated by combustion energy of the fuel at the first A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag

For fixed or towed turbines, the efficiency tends to be quite low. An example of power output is about 100 watts in a flow of 4 metres per second from a rotor diameter of about 30cm. The maximum power in that flow is about (4^3) x 0.5 x 1000 x 0.07 = just over 2000 watts. So the efficiency is just under 5% (100/2000) When used as a hydro turbine the principle is the same but acts in reverse. The water enters the screw at the top and the weight of the water pushes on the helical flights, allowing the water to fall to the lower level and causing the screw to rotate Basic working principle is to use electronic components control voltage, when the load change generator run with high speed, voltage rise, the electronic components will transfer the excessive electricity into another dump load (normally a resistive heater), and finally make sure the client with stable voltage and current, so that it can protect your micro hydro generator working safely Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water.
