黄龙滩水电厂170MW机组调速系统建模

Modeling of 170MW Unit Governor System of Huanglongtan Hydropower Plant

根据黄龙滩水电厂170 MW机组调速系统建模参数的现场实测,提供了真实的调速系统建模参数和曲线,建立了在并网状态下与实际系统状况相吻合的调速系统数学模型。仿真结果表明:所建模型能较好地反映系统在并网状态下对频率变化的动态响应。

The factual model parameter and curve of governor system is obtained by field measurement of 170 MW unit governor system of Huanglongtan hydropower plant,and the mathematical governer system model that accords＂ with the factual situation under synchronization condition is established. Simulation results indicate that the dynamic response of system can be better reflected by the model for variety of frequency under the sychronization condition.
