摘要
线间潮流控制器(IPFC)能实现不同线路间功率的定向、定量交互,解决电网潮流分布不均的问题,具有较好的应用前景。然而,目前用于大电网分析计算的主流软件中均未开发IPFC模型,导致难以对其控制潜力及应用前景进行评估。文中研究了电力系统综合程序(PSASP)下的IPFC建模方法。首先,采用功率注入法推导了IPFC装置的数学表达式。在此基础上,基于PSASP软件的用户自定义(UD)功能,搭建了IPFC的稳态控制模型,并给出了IPFC的潮流计算原理和实现方法,完成了PSASP潮流程序和用户自定义模型之间的交互迭代。仿真算例验证了文中所建模型的有效性和准确性。
Interline power flow controller(IPFC)can achieve power orientation,quantitative interaction between different lines and solve uneven distribution of grid flow and has a very good application prospect.However,the IPFC model is not developed in the mainstream software for the calculation and analysis bulk power grid,which makes it difficult to evaluate its control potential and application prospects.In this paper,the modeling method of IPFC based on PSASP is studied.Firstly,the mathematical expression of the IPFC device is derived by the use of power injection method.On this basis,the steady control model of IPFC is set up based on the user-defined(UD)function of PSASP software,and the flow calculation principle and achievement method of IPFC is given,thus interactive iteration between PSASP flow program and user definition model is finished.The effectiveness and correctness of the set up model in the paper is verified by the simulation and calculation example.
