摘要

电站引风机喘振的危害较大，故障数据的匮乏制约了喘振的预警诊断与先兆特征识别。基于仿真软件Apros建立电站引风机及其上下游烟道与设备的总体模型，在模型准确性验证的基础上进行了喘振仿真试验，并根据试验结果分析了引风机喘振的先兆特征。仿真试验结果表明：局部位置阻力越大，喘振的周期越短；阻力发生在引风机上游，阻力区至单侧烟道末端空间随喘振交替储放质，阻力区上游各区域质量容量基本不变，可以将烟道各处流动参数变化作为先兆特征识别喘振；引风机及其下游阻力增加，喘振发生在除尘器后至单侧烟道末端空间内，喘振的识别依赖此区域内各位置流动参数的监测；两侧烟道具有相互补偿作用，公共烟道阻力过大会使两侧风机均发生喘振。

Abstract

Surge is a harmful fault of induced draft fan in power station while the lack of fault data restricts the identification and prevention of surge. The overall model of induced draft fan as well as its upstream and downstream duct and equipment is established based on simulation software Apros

and the surge simulation test is carried out after verifying the accuracy of the model. Precursory characteristics of induced draft fan surge are analyzed according to the test results. The simulation test results show that

greater flue resistance leads to shorter surge period. When the resistance occurs upstream of the induced draft fan

the space from the resistance area to the end of the duct on one side will store and release mass alternately during surge

while the storage mass in areas upstream of the resistance area is basically unchanged. The change of flow parameters at different positions of the duct can be used as precursor features to identify surge. When the downstream resistance of the induced draft fan increases

the surge occurs in the space from the back of the dust collector to the end of the duct on one side. The identification of surge depends on the monitoring of the flow parameters at each position in this area. The flow on both sides can compensate each other

and excessive resistance of public duct will cause surge of fans on both sides.
