| 摘 要： | 高压大容量变频调速系统在某些应用场合,常伴随有电源瞬间跌落或消失的工况.功率电源瞬间失电跨越,是高压大容量变频调速系统的必备功能之一.本文结合实际的高压大容量变频器的控制和保护系统设计,提出了一种新的失电跨越控制策略.文中详细分析了这种策略的原理,控制及保护逻辑,最后给出样机试验结果.

| Abstract: | The voltage sag or instant power loss often happens in power supply system in medium voltage(MV) inverter's working environment.Frequent start MV inverter-motor system causes great harm to the normal production.As the most important function of MV inverters,a new control strategy of power loss ride through(PLRT) is investigated.Based on the brake of quickly reducing output frequency,the PLRT maintains the DC link voltage in a proper range.The principle,process and function design of PLRT are developed in this paper.The test results in a 55kW 3-level inverter show that this PLRT is an efficient and feasible key to the instant power loss. |
