摘要
通过模拟机验证分析机组蒸汽供能改造后系统运行参数的变化,评估改造对机组运行的影响并提出运行优化建议,供设计参考以完善蒸汽供能改造后的机组控制.从机组运行控制方式、功率失配量计算、蒸汽凝结水回水、汽轮发电机快速升负荷、发电机功率下降方面对机组控制逻辑进行分析,评估上述因素对机组运行的影响,对核电厂蒸汽供能改造后的运行控制提出优化建议,为蒸汽供能改造的核电机组或新建核能供热(供汽)机组提供设计参考.
Abstract
The changes of system operating parameters after retrofitting the steam turbines with steam supply function in an actual nuclear plant are verified and analyzed by simulator to evaluate the impact of retrofit on unit operation and put forward optimization suggestions.The unit control logic is analyzed and evaluated from the aspects of unit operation con-trol mode,power mismatch calculation,steam condensate water recycling,rapid load increase of turbin-generator,and generator load rejection to evaluate the impact of the above factors on unit operation.Optimization suggestions for opera-tion control of the plant after retrofit are put forward,which can provide design reference for nuclear plants modified with steam energy supply or newly built nuclear energy heating(steam supply)units.
