摘　　要：以贵州省某未来低碳社区为例进行负荷分析,并研究了以电定热和以冷定电2种运行策略下内燃机发电机组发电量(N_(el))和溴化锂机组制冷量(Q_(ac))对市外电网输入电量(E_(grid))、天然气消耗量(V_(ng))、生物质原料消耗量(m_(bio))和CO_(2)气体减排率(C_(cer))等参数的影响。结果表明:该社区全年耗电量、采暖负荷和冷负荷分别为8.28×10^(8)(kW·h)/a、2.457×10^(9) MJ/a和1.564×10^(9) MJ/a,所占比例分别为42.57%、35.1%和22.33%;当N_(el)和Q_(ac)分别为2064 kW和1900 kW时,2种运行策略下住宅1区的E_(grid)、V_(ng)和m_(bio)分别为0 kW、2971 kW、5392 kW和0 kW、2701 kW、6488 kW,C_(cer)最大值为71%。Taking one future low carbon community located in Guizhou province as an example,the load analysis was conducted.The effects of electricity generation capacity of internal combustion engine generator units(N_(el))and cooling capacity of lithium bromide units(Q_(ac))on input electricity from the grid outside(E_(grid)),natural gas consumption(V_(ng)),biomass raw material consumption(m_(bio)) and CO_(2) emission reduction rate(C_(cer))were studied under'following the electric load'and'following the cooling load'strategies.Results show that the annual electricity consumption,heating load and cooling load of the community are 8.28×10^(8) kW·h,2.457×10^(9) MJ and 1.564×10^(9) MJ,respectively,with the proportions of 42.57%,35.1%and 22.33%.When the values of N_(el) and Q_(ac) are 2064 kW and 1900 kW respectively,it can be found that the values of E_(grid),V_(ng) and m_(bio) in residential zone one are 0 kW/2971 kW/5392 kW under'following the electric load'strategy and 0 kW/2701 kW/6488 kW under'following the cooling load'strategy,and the maximum value of C_(cer) can reach 71%.
