“nxgxuk”黄河干流海拔最nxgxuk高的玛尔挡水电站全部机组并网发电

  中新nxgxuk社西宁12月31日电 (诸葛nxgxuk瑞鑫)国家能源集团青海玛尔挡水电站全部机组12月31日上午并网发电。这是黄河上游青海段首个千万千瓦级“水风光蓄”多能互补全清洁能源一体化项目核心工程,也是黄河干流海拔最高水电站。

  玛尔挡水电站位于青海省果洛藏族自治州玛沁县拉加镇上游约5千米的黄河干流上,所处地区平均海拔3.3千米,安装四台单机容量为550兆瓦和一台单机容量为120兆瓦的水轮发电机组,总装机容量232万千瓦,是黄河干流建成海拔最高、装机最大的水电站,也是国家实施“西电东送”和“青电入豫”的骨干电源点。

  玛尔挡水电站在国内首次采用大型水轮机组长时调相与动态调控关键技术,可根据电网需求灵活调整机组运行状态,既能在发电时全容量输出有功功率,又能在需要时快速转变为调相机,为电网提供稳定的无功功率支撑。同时,在国内水电行业也首次应用融合人工智能等技术的自主可控智能分散控制系统(iDCS),国家能源集团科环智深公司副总经理田雨聪介绍,该系统可自动诊断、预警设备及工艺系统故障,实现电力监控系统软硬件平台的全部国产化,让发电更安全高效。

  国家能源集团玛尔挡水电站总经理陈玉林表示,玛尔挡水电站的全面投产,不仅通过“西电东送”有效缓解中部地区大城市用电需求,也标志着千万千瓦级“水风光蓄”一体化清洁能源大基地建设进入新阶段,推动青海省清洁能源产业发展以及国家绿色低碳发展。

  据测算,玛尔挡水电站全部投产后,平均年发清洁电量将达73.04亿千瓦时,可满足182.5万个年用电量为4000千瓦时的家庭用电需求。

  据介绍,在建设过程中,玛尔挡水电站还采取“边施工、边恢复”措施,补植移栽超58000株青海云杉和祁连圆柏,复绿面积超250亩,生态修复和植被恢复指数达100%以上。此外,水电站大坝蓄水形成的水库增加了库区湿度和降水,促进了湿地生态系统的形成,有效改善了三江源保护区内水生生物、两栖动物和涉水鸟类的生存环境。(完)
