两个细则下超临界直流炉机组响应探究

摘要

随着电网两个细则的实施，电网对机组的快速响应提出更高的要求。要求机组在锅炉跟随协调方式下能快速响应电网负荷并保证机组压力和温度的的稳定。本文采用压力定值反向闭锁，磨带粉启动，升降负荷压力定值回路变参数以及中间点温度修正燃料前馈等一系列手段，保证机组对负荷的快速响应和自身压力、温度的稳定。%With the implementation of the two rules, the power grids make higher demands on the generator's rapid response.The generator's rapid response to electrical load as well as the stability ensure of the generator's pressure and temperature are demanded. In this paper a series of measures such as, pressure reverse lockout, mill start with coal, pressure loop variable parameter setting values, the midpoint temperature correction of fuel and a series of feed forward means of Load Change have been taken to ensure the generator's rapid response to the load as well as its own pressure and temperature stability.
