龙滩电站水轮机及调节系统仿真建模

Simulation and Modeling of Hydro-turbine and Regulation System in LongTan Station

根据水轮机及其控制系统的构架和运行机理,结合电力系统对原动机及调节系统仿真计算指导要求,通过现场试验测试及线下数据分析,建立了龙滩水电站的仿真计算模型,完成了对水轮机及调节系统中已知参数的校验,和未知参数的辨识。同时,也验证了计算中所使用的仿真数学模型能准确合理描述被仿真对象,为电力系统实现联合仿真计算提供了可靠的数据依据。

The simulation model of Longtan hydropower station is built, based on the structure and operation principle of hydro turbine and its regulation system, the simulation guide of power system prime mover and its regulation system, and field tests and offline data analysis. The verification of known data of the hydro turbine and its regulation system and the identification of unknown data are finished. It is also testified that the proposed simulation model can describe the object precisely and reasonably, which can provide reliable data for the realization of co-simulation of power system.
