Core Viewpoint - The article highlights the operational status and maintenance of the Yinjiang Hydropower Station, emphasizing its significance in the Sichuan hydropower sector and the advancements in technology used in the facility [3][4]. Group 1: Hydropower Station Overview - The Yinjiang Hydropower Station has successfully integrated all six units into the grid, contributing to Sichuan's total hydropower installed capacity exceeding 100 million kilowatts [3]. - The station utilizes bulb-type turbine generators, which are designed to maximize the advantages of high inflow, with the largest single unit capacity in Asia and a turbine diameter of 7.95 meters [3]. Group 2: Maintenance and Performance Testing - Routine maintenance, referred to as a "health check," is conducted on the generator units to ensure optimal performance, with the first unit undergoing testing after a year of operation [4]. - The testing process involves applying increasing voltage levels to the generator's stator, confirming that the insulation performance remains within acceptable limits, indicating the generator is in excellent working condition [4]. Group 3: Future Plans and Efficiency Improvements - The company aims to complete the dismantling of downstream cofferdams before the Spring Festival, allowing the hydropower station to reach a reservoir level of 998.5 meters [5]. - Efforts are being made to optimize the operational plans for the generator units to enhance efficiency and maximize electricity generation from the available water flow [5].

"时隔一年多，首台机组该例行'体检'了，我们来'把把脉'。"作为四川省能投攀枝花水电开发有限公司 生产技术部工程师，杨勇全程参与了水电站建设和运营，对这里"门儿清"。 四川攀枝花，金沙江水，奔涌不息，如万马奔腾。 "走，给水电机组做'体检'！"一早，杨勇挎着工具包，与记者一起进入银江水电站中控室。 屏幕上，电器组接线图密密麻麻。"红色的圆圈表示机组在运行，绿色的是备用，白色的处于检修状 态。"杨勇一指，"喏，今儿要检修的就是白色的一号机组。" 2024年12月，银江水电站首台机组并网发电。去年12月，最后一台机组也顺利并网，水电站6台机组全 面投产。至此，四川水电装机规模突破1亿千瓦。 一通检修下来，临近中午。记者与杨勇走出厂房，登上坝体。向上游看，高峡平湖，烟波浩渺；向下游 望，碧波荡漾，激流拍岸。 不远处，江边的挖掘机响声不停，运输车辆来来往往。站在坝顶，杨勇满怀信心："春节前，我们要把 下游的三期围堰拆除完毕，让水电站逐渐达到高程998.5米的蓄水位。"这段日子，他和同事们紧锣密鼓 地调整发电机组运行方案，争取最大程度利用径流量，不断提升设备的利用效率，让机组发好电，发足 电。 "银江水电站是金沙江中游 ...
