双路供电集成电源装置(IPS)是一种抑制电压暂降和短时中断等电能质量问题的新型装置。该装置集AC/DC变换、DC/DC变换和DC/AC变换于一体,有效地解决了许多敏感电力负荷用户所关心的电能质量问题。对IPS装置的工作原理和结构进行了简单的介绍,对IPS所采用的抑制电压暂降的控制策略进行了分析对比和仿真,研究其电压暂降抑制效果与动态响应特性。同时利用电压扰动发生装置(IG)发生电压暂降,进行大量的电压暂降抑制实验,仿真分析和实验结果均表明该装置可以有效地抑制电压暂降和短时中断等电能质量问题。
Dual Power Integrated Power Unit (IPS) is a new type of device that suppresses power quality issues such as voltage dips and short interruptions. The device combines AC / DC conversion, DC / DC conversion and DC / AC conversion in one effectively solve the power quality problems of many sensitive power load users. The working principle and structure of the IPS device are briefly introduced. The control strategy of the voltage sag used in the IPS is analyzed and compared, and the suppression effect and dynamic response characteristics of the voltage sag are studied. At the same time, a large number of voltage sag suppression experiments were carried out using voltage sag device (IG). Simulation results and experimental results show that the device can effectively suppress power quality problems such as voltage sag and short-time interruption.
