顺阀控制引起参数摆动问题的探讨与研究

The research and probing on the problem of the charge swaying with sequence valve controlling

文章通过对机组顺阀控制时出现负荷、燃料等参数摆动问题的研究与分析,得出高负荷工况下3号高压调门参与调节并且当其开度处于其开度曲线的拐点处时参数波动将会被扩大,影响机组的安全运行。并提出相应的处理措施和建议,为其它电厂同类机组的安全运行和DCS厂家的设计提供依据和参考。

The problem of the parameters such as fuel and charge swinging with sequence valve controlling was researched and analyzed,and the result is that the parameters fluctuations will be expanded when the participation of the third high pressure regulating valve and its opening is in the inflexion of the opening curves under the conditions of high charge,and it influences the safe operation of unit. And some corresponding measures and suggestions were put forward, the foundation and reference axe offered for the safe operation of other similar power units and the design of DCS manufacturers.
