Contrasting and simulating the principle of the grid-connection with load and with no load,the generator of the load cutting-in control can control wind energy in cooperate with wind turbine,which can relieves the stress of windturbine from wind and improve the speed adjustment ability of system.

The no-load cutting-in control is compared with the direct cutting-in control.

Through the analysis of the vector no-load cutting-in control strategy of VSCF doubly-fed induction generator(DFIG), equations that show how DFIG parameter perturbations during the cutting-in process influence the stator voltage are presented.

To describe the design plan of hardware of PLC simulating experiment system which includes purify electrical source,carrier wave signal source,noise signal source,load network combined with the transmit character of PLC,and presenting hardware circuit diagram of each parts.

Analysis on Network Load of Web Treeview Based on Two Kinds of Technology;

Through lots of experiments, two important conclusions are obtained: one about the relationship between runtime of parallel programs and CPU load, and the other about the relationship between runtime and network load.

A new entity organization mechanism that can heavily decrease network loads has been proposed in this paper.
