摘要
结合华能上安电厂1#机组(350 MW)空预器密封间隙系统技术改造,采用N-90分散控制系统对原系统方案、控制逻辑、信号放大器等进行了更新设计改造。运行结果表明,改造后系统信号稳定,线性调整范围增大,漏风量减小。
New design on plan, control logic and signal amplifier etc of 350MW unit AH sealed interval by using N-90 DCS is described. The results are proved signal stability, wide adjust range and reduced air leak rate.
