摘要
为了更加直观有效地分析流域梯级链式水电接入电力系统的功率穿越、电压分布等特点及其对水电安全生产的影响,文章以大渡河流域“瀑−深−枕”三站网络为研究对象,利用全数字电力系统仿真器(advanced digital power system simulator,ADPSS)的图模一体化功能开展潮流建模与计算,并进一步在自动电压控制(automatic voltage control,AVC)响应的多场景下进行无功电压仿真分析。首先,从物理元件、网络等值、参数设置等方面入手,建立系统仿真模型;然后,根据电站投入AVC的不同组合,设置多种潮流计算场景;最后,基于实际运行数据构建应用算例并进行无功电压指标对比。仿真结果表明:与实际数据吻合度达99%以上,为后续开展水电富集地区电网运行控制研究提供了有益的参考。
In this paper,to more intuitively and effectively analyze the characteristics of power traversal,voltage distribution,and their impact on the safe production of hydropower when chain-structured cascade hydropower stations were connected to the power system,the'P-S-Z'three-station network in the Dadu River Basin was taken as the research object and the advanced digital power system simulator(ADPSS)integrated function was used for power flow modeling and calculation.Furthermore,their reactive power and voltage simulation analysis was conducted in the multiple scenarios of automatic voltage control(AVC)response.Firstly,starting from the aspects of physical components,network equivalence,parameter settings,etc.,a system simulation model was established.Then,according to the different combinations of the power stations put into AVC,various power flow calculation scenarios were set up.Finally,based on the actual operation data,an application example was constructed,and the reactive power and voltage indicators were compared.The simulation results show that the calculation accuracy can reach over 99%,which provides a valuable reference for subsequent research on power grid operation control in areas with abundant hydropower.
