It limits, as long as can cool down to photovoltaic power generation plate.
Cooling water system is (to can be normal-temperature water by inputting water at low temperature and be also possible to water at low temperature, as long as comparing photovoltaic power generation
The water that the temperature of plate is low is ok) so that water at low temperature absorbs the heat of photovoltaic power generation plate when flowing through photovoltaic power generation plate, to reach
To the purpose to cool down for photovoltaic power generation plate, the cooling water for flowing through photovoltaic power generation plate can be increased because absorbing heat, temperature, high-temperature water from
The water outlet of cooling water system flows out.Therefore, the cooling water system may include sequentially connected photovoltaic hot systems normal-temperature water
Input pipe, cooling water pipeline and photovoltaic hot systems high temperature water delivery pipe, and using the photovoltaic hot systems high temperature water delivery pipe as
The outlet pipe of the cooling water system.Here cooling water pipeline can be photovoltaic heat pipe, water pipe, water channel etc., specific to select
It can be comprehensively considered by user according to actual cost and effect and be selected, carry out temperature transmitting by then passing through heat exchange, because
The tubing and layout of this cooling water pipeline and its cooling effect that will affect cooling water system with the thermal coupling relationship of photovoltaic power generation plate
Fruit, photovoltaic power generation plate temperature reduces bigger during photovoltaic power generation, and generating efficiency is promoted bigger；It needs in actual use
It accounts for, the present embodiment does not limit the material of cooling water pipeline and the layout type of cooling water pipeline.
With the outlet pipe of the cooling water system, the power generation water inlet pipe of solar-thermal generating system and solar-thermal generating system
Light boiler is connected, and improves the hybrid system of the smooth boiler heating water water temperature.
Wherein, the power generation of hybrid system mainly generates cooling water system high-temperature water and existing solar-thermal generating system is used
Water is mixed, to achieve the purpose that the power generation water for increasing solar-thermal generating system, so that reaching what light boiler was heated
The temperature of water has large increase compared with the prior art, to accelerate the speed that light boiler generates high-temperature high-pressure steam, in turn
Improve the generating efficiency of solar-thermal generating system.
Wherein hybrid system can by high temperature water inlet pipe, that is, photovoltaic hot systems high-temperature water stocking system high temperature water delivery pipe,

In order to further increase the utilizing status and cooling effect of cooling water in cooling water system, need to consider that cooling water exists
Flowing velocity in cooling pipe, flowing is too fast, can not absorb excessive heat, not only cooling effect difference and the benefit of cooling water
It is also low with effect, therefore the cooling water flow velocity of switch control need to be set in cooling pipe.Such as it is anti-in water outlet setting switch
The only too fast outflow of cooling water, can also be cooling by two switch comprehensively controls respectively in inlet and exit setting switch
The temperature of water.Based on the above embodiment, the photovoltaic hot systems room temperature water inlet pipe is provided with electronic control gate valve, for controlling
Water inlet flow velocity；The photovoltaic hot systems high temperature water delivery pipe is provided with electronic control gate valve, for controlling water discharge speed.
Wherein, room temperature water inlet pipe and high temperature water delivery pipe automatically control its aperture by electronic control gate valve, control respectively
System water inlet flow velocity and water outlet flowing water, and then accurately control cooling water temperature.Promote cooling water effect.
The principal element for influencing this water mixing heating effect is the hot water temperature of photovoltaic hot systems, solar-thermal generating system hair
Electric coolant-temperature gage and its hybrid mode and ratio, feeding solar-thermal generating system light boiler room temperature coolant-temperature gage is higher, power generation effect
Rate is promoted bigger；Based on above-mentioned any embodiment, the cooling water system further include:
It is connected with the outlet pipe of the cooling water system, the high-temperature water for storing the high-temperature water of the cooling water system output is deposited
Store up equipment.
Wherein, high-temperature water storage equipment here can be stored by high-temperature water storage tank and with photovoltaic hot systems high-temperature water
System high temperature water delivery pipe composition, in order to guarantee the temperature of hot water in high-temperature water tank, high-temperature water water tank should have heat-insulated function
Energy.By providing the equipment of deposit hot water, it is ensured that there is the power generation of enough high-temperature water and solar-thermal generating system to be carried out with water
Mixing.
Photovoltaic-light-heat integration electricity generation system is photovoltaic generating system and solar-thermal generating system to be carried out networking, therefore be somebody's turn to do
System further includes photovoltaic-light-heat integration electricity generation system network device, is based on above-mentioned any embodiment, the system further include:
It is connected with the transformer of the transformer of the photovoltaic generating system and the solar-thermal generating system, is used for photovoltaic
Generated output collects with photo-thermal power generation power, and inputs the total high voltage bus power equipment of network system.
Wherein, the solar-thermal generating system of the high voltage bus electric system altogether boosts to voltage through transformer, photovoltaic hair
Electric system boosts to voltage through transformer, photovoltaic-light-heat integration electricity generation system power is by high voltage busIt is conveyed by route
It goes out.
Optionally, the high voltage bus power equipment altogether includes:
Photovoltaic-the photo-thermal being connected with the transformer of the transformer of the photovoltaic generating system and the solar-thermal generating system
The high voltage bus of integrated power generation system；
The high-pressure side reactive power compensator being connected with the high voltage bus.The high-pressure side reactive power compensator can be static
