摘要:
提出了基于热力参数-性能指标特性曲线的诊断模型.首先过滤定功率情况下电站汽机阀门开度变化对性能指标的影响,定性分析部件发生故障时性能指标相比于参考工况的实际变化量,以消除部件之间的相互影响.然后确定了热力参数的选取原则,引入热经济学结构理论中的不可逆损失作为性能指标,利用所建模型定量计算故障工况下各部件的性能指标变化量,用以诊断发生故障的部件.最后运用APROS仿真软件模拟某电厂330 MW机组的多种故障工况,将提出的方法应用于故障诊断,初步证明了模型的可行性.
Abstract:
The diagnosis model based on the thermodynamic parameter-performance curve is proposed. First, the effect of a valve on performance indicator is filtered under constant power condition in a power plant, and the change of performance indicator compared to reference condition in malfunction component is qualitatively analyzed, which can eliminate the interaction between the components. Then the principle of selecting thermal parameters is determined. The irreversibility in the thermoeconomic structural theory is selected as a performance indicator, and the change of the indicator quantitatively calculated using the model. APROS(advanced process simulator)simulation software is applied to simulate a variety of fault conditions for a 330 MW unit, and the proposed model is used for malfunction diagnosis to prove its feasibility.
