Compared with MW system, Small wind generators mainly recharge batteries, application 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 energy 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. Due to 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 turbine grid-connected power system contains wind driven generatorport unloadedgrid-connected inverter power distribution equipment.
When the wind speed reaches the cut-in wind speed, after certificationinvertion, the AC power generated from the wind generator feeds into grid.
