Solar and Wind Hybrid Generation Systems

The

is

now

strong

in

people

to

the

electricity.

It

is

being

the

the

power supply system becomes the power source which the people most need, needs

the

the

system

.It

is

reasonable

in

this

kind

of

leeward

light

supplementary

system,

because the

modern

service

still

could

not

achieve

the place

was the trough hides the rich wind to be able with the solar energy resources place.

Moreover

the

Therefore

regarding satisfies the remote districts energy to need with the Chinese most poor

electricity

generation, after the accumulator cell stored

energy, to the load power supply one

kind

of

source,

widely

applies

at

present

in

the

emblem

wave

correspondence, the base depot, the broadcasting station, the open country activity,

the highway, the radio mountainous area, the village and the island.

Remote districts use electricity the load not to be all big generally, therefore is

uneconomical

with

the

electrical

network

power

transmission,

directly

generates

electricity

commonly

used

in

the

uses

the

engine .But

the

diesel oil storage and transport too is high to the remote districts cost, therefore the

diesel

engine

only

can

take

one

kind

of

solve

the

problem,

only

can

the surface air temperature forms the air convection to produce differently creates
