(一) 华东电网严重缺电增建调峰电站刻不容缓华东电网近年来缺电严重,尤其是随着用电结构的变化,峰谷差逐年增大,调峰问题日趋突出。据1982～1987年实际出现的负荷资料统计,最高负荷年平均增长率为8.79%,峰谷差年平均增长率为8.56%。峰谷差与最高负荷同步增汝,达到最高负荷的30%左右。电网内现有水电227.17万kW,其中调峰容量约130万kW。而火电调峰能力有限,且火电调峰电网运行不经济。据对现有火电机组实际调峰能力调查,各类燃油、燃煤机组的负载可调幅度上海市为38%
(A) East China Power Grid serious shortage of power to build peak power station without delay Huadong Power Grid in recent years, lack of power serious, especially with the changes in power structure, the peak valley difference increases year by year, peak regulation problems have become increasingly prominent. According to the actual load data from 1982 to 1987, the average annual growth rate of the maximum load was 8.79% and the average annual growth rate of the peak and valley years was 8.56%. The difference between the peak valley and the maximum load increased by the same period, reaching about 30% of the maximum load. The existing hydropower 2,270,1700 kW, of which peak capacity of about 1.3 million kW. The thermal power peak regulation capacity is limited, and thermal power peaking grid is not economical. According to the investigation of the actual peaking power of existing thermal power units, the adjustable load of various types of fuel and coal-fired units in Shanghai is 38%
