Study On The Matching Characteristics Of Distributed Wind Power And Heating In Severe Sold C Area

With the development of green buildings in cities and towns,the state has vigorously promoted renewable energy sources,and collected and applied renewable energy such as solar energy and wind energy in the field of building energy conservation research.It will become an inevitable trend for sustainable development of the construction industry in the future.This article takes the cold residential area of the C residential building as the research object,constructs the numerical model of the direct benefit type combined with the additional sunlight room type building,carries on the load computation analysis to the different window wall and building than the building,obtains the south facing window wall ratio to the architectural indoor temperature influence,The building model structure with the highest solar energy guaranteed rate was obtained;the laser radar anemometer was used to monitor the test area in real time;local meteorological data was collected for analysis and local wind environment data was obtained;and wind turbines were used for power generation heating,design and construction.Wind turbine power test platform,real-time monitoring of the output power of the wind turbine under natural wind conditions,and plotting the power characteristic curve to calculate the annual power generation of the wind turbine;comparing the building load and the annual power generation of the wind turbine,and analyzing the distribution of the sun-wind turbine Matching characteristics of heating,to explore the matching characteristics of distributed household wind power heating in cold area C.The load of the ordinary buildings in Zone C of the cold area was selected to calculate the total thermal load of the building for the year 6816.40 kW·h,and the cumulative heat load of the heating season was 6422.98 kW·h;the ratio of the direct-benefit passive house to the south-facing window and wall was increased.Large,increase in the amount of heat in the day room;add 1.2m×9m of sunlight outside the room to the south,analyze the heating season load of the passive room building with additional sunlight,compared with ordinary buildings,reduced by 30%;combine the passive room of the two ways The building’s total solar thermal load is 3991.35 kW·h for the solar-enclosed building with a window-to-wall ratio of 0.8.The total building load for the heating season is 2986 kW·h,which is 41%lower than that of the ordinary building.At this time,the maximum solar energy guarantee rate for the heating season is 55%.Design and build an off-grid wind turbine power test platform to monitor the real-time output power of the wind turbine under natural wind conditions and plot the actual wind speed-power curve of the wind turbine,verifying that there is a large difference between the theoretical power curve and the actual power curve of the wind turbine;the collected power scatter points are fitted,and the six-degree polynomial curve is used to make the wind turbine power prediction result more accurate;the forecasted annual output of the wind turbine is 2833 kW·h.The guarantee rate is 23%,the heating capacity of heating wind turbines is 1112kW·h,and the guarantee rate of heating during heating season is 37%;the building thermal load index during heating season is 15.53 W/m~2,and the power supply index of wind turbines is 5.74W/m~2.The average guaranteed heating rate per square meter of wind turbines during the heating season is 45%.In summary,for the ordinary residential buildings in the cold C area,combined with the direct benefit type and additional sun room type passive house construction,while using the 1500W wind turbine power generation heating,the average coldest month heating guarantee rate is 45%,in order to ensure winter The heating room temperature can be combined with the air source heat pump to assist the building.
