摘要
传统的火电厂协调控制系统很难满足新形势下电网的要求,为进行分析和优化,需要建立机组的负荷-压力数学模型。以华电漯河发电有限公司一期2×330 MW机组为对象,在机理分析的基础上建立了机组的数学模型,根据历史数据及动态试验结果确定了相关模型参数,并在对象机组分散控制系统中搭建了机组简化模型。通过与机组实际运行数据对比,证明了该模型具有较好的准确性与复现性。机组模型的建立可为下一步先进控制算法的应用打下良好的基础。
The coordinated control system of traditional thermal power plant is difficult to meet the requirements of power grid under new circumstances. In order to make an analysis and optimization of the system,a load-pressure mathematical model of unit should be established. Taking the 2 × 330 MW units of the first phase of Huadian Luohe Power Generation Company Limited as examples,this paper established the mathematical model of units on the basis of mechanism analysis,and confirmed the model parameters according to the historical data and the results of dynamic test. In addition,a simplified model was also built for the distributed control systems of objected units. Through comparing the model results with actual operation data of units,it was proved that the model has good accuracy and reproducibility. The establishment of unit model could lay a good foundation for the future application of advanced control algorithm.
