LUO Jian-ping1, ZHANG Chang-qing2, WANG Xiao-cheng21.Guohua Jinjie Energy Co Ltd. RB CONTROL STRATEGY FOR UNIT NO.3 IN GUOHUA JINJIE ENERGY CO LTD AND TEST THEREOF[J]. Thermal power generation, 2009, 38(1): 92-95. DOI: 10.19666/j.rlfd.2009.01.026.
The test process of run back(RB)function for unit no.3 in Jinjie Energy Co Ltd has been presented.Directing against controlling water-level in the steam drum and controlling pressure in the furnace during the test process
the control tactics adopted
such as enhancing the set value of main steam pressure
optimizing feed forward of the steam flow rate
as well as propery tripping velocity of coal pulverizer and decreasing the velocity of fuel command during RB process of the primary air fan
etc.
has been analysed.Through test
the effectiveness of above-mentioned tactics has been verified.
