定起草。

本文件代替GB/T31461—2015《火力發(fā)電機組快速減負荷控制技術(shù)導(dǎo)則》，與GB/T31461—2015相

比，除結(jié)構(gòu)調(diào)整和編輯性改動外，主要技術(shù)變化如下：

a）增加了RB的技術(shù)要求（見第4章）；

b）增加了RB動態(tài)試驗內(nèi)容（見5.2.2）；

c）增加了FCB設(shè)計要求（見7.3）；

d）增加了FCB動態(tài)試驗條件（見8.2.1）；

e）將規(guī)范性附錄更改為資料性附錄，更改了機組總體RB動作/試驗情況一覽表（見附錄A、

附錄B、附錄C、附錄D，2015年版的附錄A、附錄B、附錄C、附錄D）。
