摘要

回顾了使用不间断电源的不同配电系统配置。在给非线性、高度敏感的关键电子设备(如计算机和可编程逻辑控制器)供电时，它们被评估为提供可靠的电源、清洁能源和最大限度地利用配电系统(装机功率)。讨论了典型配电系统的质量问题及解决方法。得到了一个广义的单位公式，并用于估计影响敏感负载的中性点对地电位。对四种配电方案的可靠性和电能质量的综合性能指标进行了估计。在一个临界非线性负荷分配系统中，电能质量问题得到了实验的支持。

High reliability and improved power quality in low voltage distribution systems for nonlinear critical loads: an evaluation

Different distribution system configurations using uninterruptible power supplies are reviewed. They are evaluated in terms of providing a reliable power supply, clean energy and maximum utilization of the distribution system (installed power) when feeding nonlinear, highly sensitive critical electronic equipment like computers and programmable logic controllers. A typical distribution system's quality problems and solutions are discussed. A generalized per unit formula is obtained and used to estimate neutral to ground potential that affects sensitive loads. Overall performance indexes regarding reliability and power quality are estimated for four distribution schemes. Power quality issues are supported by experimental in a critical nonlinear load distribution systems.
