摘　　要：针对无功优化传统算法和人工智能算法均存在内存不足、收敛速度等维数灾难且难以寻得全局最优解等工程应用问题,提出一种基于静态、暂态电压稳定约束的无功补偿配置方法。通过无功分层分区平衡分析、静态电压稳定分析和暂态电压稳定校核的综合优化,制定合理的无功补偿最终配置方案。通过PSD-BPA电力系统仿真软件对实际区域电网的分析计算表明,采用本方法可以明显提高无功补偿配置的准确性和有效性,避免不必要的投资,减少浪费,同时大大增强了电网抵抗电压失稳风险的能力,提高了电网安全稳定高效经济运行水平。Targeting at engineering application problems existing in traditional reactive power optimization algorithms and artificial intelligence algorithms, such as dimension disaster of insufficient memory or the convergence speed, and the difficulty in finding a global optimal solution, a method for reactive power compensation configuration based on static and transient voltage stability constraints is proposed. By reactive hierarchical partition balance analysis, static voltage stability analysis and transient voltage stability checking program, the final configuration of reasonable reactive power compensation scheme is formulated. By PSD-BPA power system simulation software on the analysis and calcula- tions of the actual regional power grid, it is indicated that this method can significantly improve the accuracy and effec- tiveness of the reactive power compensation, thereby avoiding unnecessary investments and reducing waste, while greatly enhancing the grid resistance to voltage instability risks, as well as improving security and stability level of the power grid at high efficient and economic operation.
