Hummer Grid-Tied Wind Turbine System : Possess of seven Core Patented technologies ,two for international patents. Super small& light structure, attractive outline design ,swift in start up Using of IGBT and MPPT technologies ,the efficiency of the generator is very high ,Stable in running . Grid-tied invert control system is research & develop by our R&D team ,produce according to UL1741 standard, the grid-tied safety is very high . Full digital visual control, can connect to PC , can achieve real time long-distance control. Multiple protect function to ensure the safety of the whole wind turbine system Hummer grid-tied wind turbine system have be sold to more than 70 countries and areas of the world . When the wind generators speed reach to hummer wind turbine's start up speed ,the rotor blades which made of high quality glass reinforced plastic will transfer the wind energy to mechanical energy, wind generator begin to work ,output Single-phase frequency conversion AC, the rectifier will convert AC into DC ,and then the inverter will convert DC into sustained AC to supply power to the grid . The unloader integrates the function of rectification and divison load . All the deigns will protect the grid-tied controller to avoid the damages of overcharging . With the advanced technology of IGBT and control processer ,hummer grid-tied inverter can work with higher power and charge voltage .If the power generated by the wind turbine is insufficient for grid operation ,the inverter remains in standby mode until the wind turbine has generated sufficient power to switch into grid-connecting mode .After all system checks have been performed ,the inverter switches from standby mode to connecting mode .In this mode the inverter is connected to the grid and delivers power to the grid . The inverter will leave this model only if disconnection or without enough wind . To protect the wind generator system the inverter will turn off the AC connection and goes into breakdowns and stop pattern if breakdown happened . When across strong wind , the wind generator maybe rotate fast ,the output voltage will reach up to a dangerous level ,and the unloader will begin to work under this situation to consume redundant power . Hummer grid-tied wind turbine system is almost no need user operation and maintenances , it is also very easy to install . In the same time , we offer a whole system of data collection ,through the RS485 wires ,user can see the running condition and all parameters from the PC . Hummer aims to be the best wind turbine manufacturer and wind power generator provide in China as well as a worldwide influential enterprise .
