摘　　要：提出了一种基于0-1整数规划算法的改进的PMU配置模型,该模型具有良好的适应性,而且0-1整数规划算法计算速度快,结果精确可靠。通过该模型可以得出全部的所需PMU数最小的优化方案,进而在该模型的基础上提出了PMU模拟通道数最小化的处理方法。该处理方法可以减少因电力系统母线数量庞大而产生的配置PMU所需的资金。最后通过对IEEE14节点系统、IEEE30节点系统以及新英格兰39节点系统的仿真计算,验证了所提出的模型和处理方法的有效性,可供相关研究者参考。This paper puts forward an improved PMU placement model based on 0-1 integer programming algorithm, which has a good adaptability. The 0-1 integer programming algorithm possesses a fast computational speed with accurate and reliable results. By this model, all optimization schemes with minimum PMU values can be got and a corresponding approach of minimizing analog channels PMU numbers is proposed. This method could effectively reduce the cost needed for PMU configuration due to its enormous bus numbers in power system. At last, the validity of this model and its processing methods can be proved by emulation calculations, including IEEE-14 buses system, IEEE-30 buses system and New England 39 buses system. For future researchers, this model（can serve as references.
