面向运行全过程的水电站技术供水系统优化模型研究

基于目前水电站技术供水系统模型不能实现一体化正常运行操作过程和故障连锁过程的现状,提出了面向水电站技术供水系统运行全过程的实用化仿真模型。首先对控制过程和动态过程进行解耦和优化,建立反映正常运行模式的基本设备模型。再利用故障连锁模式与正常运行模式的逻辑相似性将故障行为融合至正常行为,实现正常状态和故障状态一体化建模。最后由设备模型搭建系统模型,实现供水系统全过程的仿真。该模型物理概念清晰、计算简洁、通用性强,在多个水电站的仿真培训系统中得到了运用,并推广至整个辅机系统。研究成果为水电站技术供水系统优化设计提供参考。

Study on full operation process oriented optimal model for technical water supply system of hydropower station

In accordance with the status quo of that the integrated model include normal operation process and the fault chain process of the technical water supply system for hydropower station cannot be realized at present，a full operation process oriented practical simulation model for the technical water supply system for hydropower station is put forward herein. At first，the control process and the dynamic process are decoupled and optimized for establishing the basic equipment model to reflect the normal operation mode. Moreover，the fault behavior is incorporated into the normal operation behavior with the logical similarity between the fault chain mode and the normal operation mode to realize the integrated modeling of both the normal condition and the fault condition. Finally，the system model is built up with the equipment model to realize the simulation of the full process of the water supply system. The model has the merits of clear physical concepts，concise calculation and strong commonality，thus is not only applied to the simulation training systems of several hydropower stations，but also popularized to the whole auxiliary system concerned. The study result provides a reference for the optimal design of the technical water supply system of hydropower station.
