摘要
建立精确的汽轮机模型对提高机组和电网稳定性有重要意义。考虑锅炉对汽轮机主蒸汽压力的影响,将锅炉的线性化增量模型加入汽轮机模型中,建立了单再热式汽轮机的改进模型。仿真及实测表明,改进模型和现有模型相比,在主蒸汽压力、电磁功率和功角等方面更符合实际情况,能更好地应用于电力系统稳定性分析。
Establishing an accurate steam turbine model is of great significance for improving the stability of power units and grid. Considering the influence of boiler on the main steam pressure of single-reheat steam turbine, the linearized incremental model of the boiler is joined to the original steam turbine model to establish an improved single-reheat steam model. The simulation results show that the improved model is closer to the reality when comparing with the original model in the main steam pressure, electromagnetic power and power angle, and can be applied in power system stability analysis.
