(一)调压井水平割面积的选择一般调压井水平剖面积受小波动稳定控制,应按托马公式选定,但太平哨水电站建成发电后并入东北电力系统,並与主网联合运行,不考虑单独运行。东北电网总容量超过500万千瓦,而太平哨水电站装机总容量为16.1万千瓦,一座调压井供两台机组用水,两台机装机容量为8.05万千瓦,占主网总容量的1～2％左右,在系统中所占比重甚小。
(A) the selection of the horizontal cutover area of the surge shaft The general cross-sectional area of the surge shaft is controlled by small fluctuations and should be selected according to the Toma formula. However, after the Taipingsutao Hydropower Station is built and connected to the power system, it is integrated with the main grid Run, do not consider running alone. The total capacity of the Northeast Power Grid exceeds 5 million kilowatts, while the total installed capacity of the Taiping Whistling Hydropower Station is 161,000 kilowatts. Two surge tanks are used for water supply to two units. The installed capacity of the two turbines is 80,500 kilowatts, accounting for 1 to 2 of the total capacity of the main grid % Or so, the proportion in the system is very small.
