摘要
针对交直流电网输电能力计算中考虑暂态稳定约束的必要性和复杂性,提出了一种考虑暂态稳定约束的交直流电网可用输电能力(Available Transfer Capability,ATC)实用计算方法。以电力系统分析综合程序为内置计算平台,以VC++编写计算流程,采用重复潮流算法实现对模型求解。以山东电网为例进行分析,计算及仿真结果表明所提方法能够考虑输电能力计算中涉及到的静态和暂态稳定约束,协调了经济性和安全性两方面,具有较好的功能性。所提算法实用性强且易于编程实现,可有效应用于实际电网的ATC计算与分析。
In this paper, a practical approach on avallao^e transfer capability（ATC） calculation for the AC/DC systems by considering transient stability constraint is proposed due to the complexity and necessity of transient stability. Power system Analysis Software Package （PSASP） is used as a built- in calculation platform, calculation procedure is writen in VC ＋ ＋ and the ATC is calculated by repeatitive power flow method. By taking Shandong Power System as example, it is verified that the proposed method could be used to calculate and analyze ATC of practical AC/DC hybrid power systems and is easy to be programmed. Calculation and simulation results show that static and transient stability constraints can be involved in ATC calculation for AC/DC transmission sys- tems by using of proposed practical method, which can coor- dinate economy and security of power system, and the meth- od had good functionality. The proposed algorithm has strong applicability and easy programming, and can effec- tively apply to ATC calculation and analysis of power grid.
