1000MW机组超低排放改造中厂用电的优化分析

Optimization Analysis on Auxiliary Power for Extra-low Emission Retrofit of 1 000 MW Generating Units

针对浙能嘉兴发电厂三期2×1 000 MW机组"超低排放环保示范工程"技术改造前后厂用电系统存在的问题,提出了相应的节电优化措施。对改造前后机组厂用电情况进行了比较和分析,为类似机组超低排放改造项目提供借鉴,使超低排放改造不仅满足现代大型火电机组环保的新要求,更能够达到节电降耗的目的。

Aiming at problems in auxiliary power before and after technical innovation of ＂Environmentalfriendly Pilot Project with Ultra-low Emissions＂ of 2×1 000 MW power generating units in phase-Ⅲ project of Zheneng Jiaxing Power Plant, the paper presents relevant power saving and optimization measures. The paper also analyzes and compares auxiliary power before and after the innovation and provides experience for extralow emission retrofit of similar power generating units, enabling the ultra-low emission innovation to satisfy the new environmental protection requirement on modern large-scale thermal power generating units and achieve the goal of energy saving and consumption reduction.
