3月22日,丹江口水电厂2号机改造增容工程竣工并网发电。试验表明,在目前上游▽140.92m的低水位及水轮机导叶开度相同的情况下,改造增容后的2号机与同类型号的前苏联制造的1号机相比,多出力0.7万kW,而上导摆度、水导摆度分别仅为0.22mm与0.40mm,完全符合技术标准。按设计要求,在设计高水位时,2号机出力将由原15万kW增加到17.5万kW。改造增容后的2号机运行稳定,为今后5台机组的改造与增容积累了宝贵的经验。 为保障设备的安全运行,将进一步提高企业的经济效益与社会效益,逐步对全厂6台单机容量15万kW的机组实施改造与增容工作。1992年,对2号机发电机部分进行了改造与增
March 22, Danjiangkou Hydropower Plant No. 2 machine transformation and capacity expansion project completed and grid-connected power generation. Experiments show that at the current ▽ 140.92m lower water level and the turbine guide vane opening under the same circumstances, the transformation of capacity after the No. 2 machine and similar models of the former Soviet-made No. 1 machine, the extra output of 7,000 kW , While the upper swing, water conductivity swing were only 0.22mm and 0.40mm, in full compliance with technical standards. According to design requirements, in the design of high water level, the output of Unit 2 will increase from the original 150000 kW to 175000 kW. After the transformation and expansion of the No. 2 machine running stable, for the future five units of the transformation and capacity accumulation has accumulated valuable experience. In order to ensure the safe operation of the equipment, the economic and social benefits of the enterprise will be further enhanced, and the transformation and capacity increase of 6 units with capacity of 150,000 kW will be gradually implemented. In 1992, some of Unit 2 generators were retrofitted and increased
