“十五”头两年,华中地区全社会用电量年均增长为9.5％,是“九五”年均增长速度的2.3倍,电力发展再次进入快速增长期。2002年,华中电网最大用电负荷达3079万千瓦,年均增长率为11.1％,峰谷差达1092万kW,增长率达7％。 有两种对比方法可帮助我们感受这两个数字的价值。一是从历史数据看增幅。从1997年到2001年这五年,华中电网最大用电负荷分别为:1719万kW、1889万kW、2011万kW、2499万kW、2684万kW,年均增长为9.9％,最大峰谷差分别为:677万kW、741万kW、821万kW、967万kW、1020万kW,年均增长率为9.22％。二是从当年数据比重看变化。2002年,华中电网峰谷差达到1092万kW的这一天为8月22日,
In the first two years of the “Tenth Five-Year Plan”, the average annual electricity consumption in central China was 9.5%, an increase of 2.3 times the average annual growth rate of the Ninth Five-Year Plan. Power development once again entered a period of rapid growth. In 2002, the largest electricity load in Huazhong Power Grid reached 30.79 million kilowatts, with an average annual growth rate of 11.1% and a peak-valley difference of 10.90 million kW, a growth rate of 7%. There are two contrasting ways to help us feel the value of these two numbers. First, from the historical data to see the increase. From 1997 to 2001, the five largest power grids in Huazhong Power Grid were respectively 17.19MW, 18.89MW, 2011MW, 2499MW and 2684MW with an average annual increase of 9.9%. The maximum peak to valley difference Respectively: 6.77 million kW, 7.41 million kW, 8.21 million kW, 9.67 million kW, 10.2 million kW, with an average annual growth rate of 9.22%. Second, look at the proportion of data changes from the year. In 2002, Huazhong Power Grid peak-valley difference reached 1092 million kW this day for August 22,
