2power2
- 在大功率DC/DC开关电源中,为了获得更大的功率，特别是为了得到大电流时，经常采用N个单元并联的方法。多个单元并联具有高可靠性，并能实现电路模块标准化等优点。然而在并联中遇到的主要问题就是电流不均，特别在加重负载时，会引起较为严重的后果。普通的均流方法是采取独立的PWM控制器的各个模块，通过电流采样反馈到PWM控制器的引脚FB或者引脚COMP，即反馈运放的输入或者输出脚来调节输出电压，从而达到均流的目的。显然，电流采样是一个关键问题：用电阻采样，损耗比较大，电流放大后畸变比较大；用电流传感器成
Coordination-and-Optimization
- 将网损价格因子和网损协调系数引入目标函数,建立了改进直流潮流模型,实现了负荷在机组间的最优分配 利用交流潮流方法计算系统实际网损,并利用增量直流潮流模型将网损在机组间进行合理分摊 最后利用交直流迭代思想修正网损价格因子和网损协调系数以优化网损分配方案。IEEE14节点和IEEE118节点算例验证了该方法的可行性,算例结果充分逼近了交流最优潮流的计算结果,符合实际系统运行状况。-The net loss and net loss of coordination price factor intro
