技术领域technical field
本申请属于燃煤电站热工自动控制技术领域，更具体地，涉及一种风量测量装置的风量预警系统及风量预警方法。The application belongs to the technical field of thermal automatic control of coal-fired power stations, and more specifically, relates to an air volume early warning system and an air volume early warning method of an air volume measurement device.
背景技术Background technique
燃煤电厂风量测量主要包括磨煤机一次风量、锅炉二次风量，各风量测点均参与机组保护和自动。由于燃煤锅炉本身原因，助燃风夹带有灰尘，当灰尘逐渐累积在风量测量装置上时，风量测量装置会出现堵塞，造成风量测量装置测量得到的信号不稳定，产生一定的波动，出现忽高忽低的情况，而如果总风量依据不稳定的信号进行调节，同样产生巨大扰动，严重时易造成锅炉的炉膛压力聚变，影响机组运行安全。The air volume measurement of coal-fired power plants mainly includes the primary air volume of the coal mill and the secondary air volume of the boiler, and each air volume measurement point participates in unit protection and automatic operation. Due to the coal-fired boiler itself, the combustion-supporting air contains dust. When the dust gradually accumulates on the air volume measuring device, the air volume measuring device will be blocked, causing the signal measured by the air volume measuring device to be unstable, resulting in certain fluctuations and sudden highs. If the total air volume is adjusted according to an unstable signal, a huge disturbance will also be generated. In serious cases, it will easily cause the furnace pressure fusion of the boiler and affect the safety of the unit operation.
目前，燃煤电厂采用人工维护的方式，定期对风量测量装置进行清理。但申请人认识到，由于电厂侧受新能源并网的影响，调峰频繁且负荷变动剧烈，锅炉送风系统变动工况远超设计值，锅炉运行存在较大的不确定性，若维修人员按照预设周期对风量测量装置进行清理，则无法及时清理发生堵塞的风量测量装置，导致风量自动控制发散，造成锅炉保护误动，影响锅炉运行安全。At present, coal-fired power plants use manual maintenance to regularly clean up the air flow measurement device. However, the applicant realized that due to the influence of new energy grid connection on the power plant side, frequent peak shaving and drastic load changes, the changing working conditions of the boiler air supply system far exceed the design value, and there is great uncertainty in boiler operation. If the air volume measurement device is cleaned periodically, the clogged air volume measurement device cannot be cleaned in time, resulting in the divergence of the automatic air volume control, causing malfunction of the boiler protection, and affecting the safety of the boiler operation.
