摘要
传统的静态安全分析研究集中在处理电力系统元件开断后的分配不平衡功率和快速潮流算法上。电网发展和安全需求的提高要求静态安全分析系统能容纳多种复杂模型,适应不同种类多个元件的切除、增加和参数修改。结合PQ分解法的收敛特性提出统一的模型处理原则;基于部分因子修正的快速算法提出因子表附加链技术;用动态网络接线分析方法减少计算用时。这些原则和方法解决了静态安全分析系统对模型和新增元件的要求,实现了快速性、准确性和收敛性相结合,具有较好的理论价值和应用前景。中国电网的算例证明了所提方法的有效性。
Traditional static state security analysis (SSSA) research focuses on fast method to balancing electric energy after removing component from power system. Development of power grid and increasing expectation of security claim more against SSSA system, namely, accommodation of various intricate apparatuses model and adaptability of removing, addition of element and modifying parameter of different equipment, in this paper, with discussing the convergence of fast decoupled load flow algorithm, universal model treatment principle was put forward. Based on partial matrix refactorization, appendant link to factor table was introduced. Furthermore, dynamic network analyzing method was used to reduce calculation time. These principles and measures satisfy the demand on model and addition equipment in SSSA, achieve comprehensive character of speedy, accurate and convergent, and own well theoretical value and application expectation. The method proposed was validated by cases of real power grid in China.
