铜街子水电站,装机4台150兆瓦水轮发电机。目前正紧张施工,力争1990年底发电。为保证电站如期发电,敦促建设单位及早签订机组技术协议和订货合同,制造厂及时提供机组图纸,就成了必要的前提。为签订机组技术协议,选择了大化、西津、富春江、新安江、葛洲坝等水电站进行调查。因这些电站(除新安江外)和铜街子一样,同属河床式电站,在机组安装、运行方面有很多相似之处,值得借鉴参考。制造厂对钢街子水电站机组十分重视,一方面在总结大化、葛洲坝等电站机组的基础上,作了必要的改进,避免上述电站机组在安装、运行过程中出现的问题重演;另一方面在
Tongjiezi Hydropower Station, installed 4 sets of 150 MW hydro-generator. Tensions are currently under construction and strive to generate electricity by the end of 1990. In order to ensure that the power station will generate electricity on schedule, it is necessary to urge the construction unit to sign the unit technical agreement and order contract as soon as possible, and the manufacturer timely provide the unit drawings. In order to sign the technical agreement of the unit, Dahua, Xijin, Fuchunjiang, Xin’anjiang and Gezhouba hydropower stations were selected for investigation. Because these power stations (except Xin’an River) and Tongjiezi belong to the same river-bed type power station, they have many similarities in terms of installation and operation of units and are worth learning from for reference. On the one hand, on the basis of summing up the power station units of Dahua and Gezhouba, the manufacturer made the necessary improvements to avoid the recurrence of the problems that occurred during the installation and operation of the power station units; on the other hand, in
