摘要
在机组不同负荷下,通过风机工频和变频运行方式特性试验,定量地说明了风机变频改造的节能效果。河南3家电厂风机变频改造后运行实践表明风机变频调节方式运行,性能稳定可靠,能满足机组各种负荷需要;对风机变频器运行测试结果显示风机变频改造后运行中产生的谐波量较少,未对电厂一、二次系统产生明显影响,符合有关国标要求。
The operation mode of draft fans in three thermal power plants in Henan Province were retrofitted to frequency control of motor speed.The operation performance of draft fans was stable and reliable,being able to satisfy variable load requirement of generating unit;and the harmonic content in frequency converter was fewer,without evident impact on the primary and secondary system of power plant,being up to the relevant national standard.
