高加单列隔离对机组的影响

The influence of high-intensity single-row isolation on the unit

本文通过某核电厂2号机组高压加热器B列隔离前后的参数对比,以及高加隔离前后机组总效率计算,得出高加单列隔离后维持核功率不变所需电功率降负荷数值,为操纵员瞬态响应提供依据。

This paper compares the parameters before and after isolation of the B-column high-pressure heater of the No.2 unit of a nuclear power plant,and calculates the total efficiency of the unit before and after the high-plus-isolation,and obtains the value of the electric power reduction load required to maintain the nuclear power unchanged after isolation and isolation.
