Abstract:

According to the ultra-high voltage (UHV) transmission project of "Xilin Gol-Jinan", the change of pollutant concentration in Beijing, Hebei, and Tianjin was simulated and evaluated by the atmospheric chemical model WRF-Chem V3.7.The influence of UHV cross-regional transmission on air quality in the affected area was evaluated by setting different locations, heights, and emissions.Results show that the project has the largest impact on the atmospheric environment of Beijing in the case of southeast wind.According to the height of the virtual plant, the concentrations of PM2.5 at the height of 9 m, 27 m, 46 m, 64 m, 91 m, 130 m, 185 m, and 255 m were calculated.It is found that the greatest influence on the concentrations of PM2.5 is induced at the height of 91 m near the power plant.After long-distance transportation, the power plant has the greatest influence on the concentrations of PM2.5 below 45 m.The project of the power plant in "Xilin Go-Jinan" has little impact on the variation of pollutants concentration in Beijing.
