As a clear renewable energy, Wind energy get more and more world attention.The quantity is large,the world wind is approximately 2.74 〜109MW,2〜107MW wind energy can be used,which is ten times bigger than the total amount of water.The wind is already being used,but now,people interested in how to use the wind to generate electricity.
To convert wind energy to mechanical energy, then convert mechanical energy to power energy ,this is wind power generation.The principle of wind power generation is using wind to take the windmill rotating blades and through the growth machine to promote the speed,to promote the generator supplying power.
Wind Energy Inverter on-grid system
Compared with MW system,Small wind generators mainly recharge batteries, applicating in a separate power supply network or system of the lake fetched water.For the application domain, there are a lot of the machines whose prices are reasonable. However,with the emergy of small wind power system,it applied the trend of the new machine in recent years.It can produce electric power and directly provide for the regular network or independent off-grid system.The new application for electricity becomes more flexible and also provides indirect power for electricity users. Blower of electrical energy can directly provide for the users,spare parts can be directly into a network,and needn¨t to be stored in the battery. Dueto save costs for expensive and maintenance costs of the battery group,these wind of the grid-connected technology to save a lot of expenditure costs.Small wind turbinegrid-connected power system contains wind driven generator、port unloader、grid-connected inverter 、powerdistribution equipment. when the wind speed reaches the cut-in wind speed,after ectification、invertion,the AC power generated fromthe wind generator feeds into grid
Single-phase series small wind turbine grid-connected inverter
Wind turbine off-grid power system contains wind turbine、controller、battery、wind turbine off-grid power special inverter power、power distribution system.Wind energy take the power generator to produce electricity by the blower and the leaves around an axis. It produces AC power, then commutates to DC power ,through wind turbine off-grid power special inverter power ,and to the local electricity load.when DC voltage is too high due to the wind speed big, the controller starting will take off over energy through port unloader.
