电压恢复时间 voltage recovery time
- 介绍开断近区故障(SLF)时恢复电压的计算和灭弧室在不同燃弧时间下的理论分析。
Introduction to calculation of recovery voltage in short line fault(SLF) and theoretical analysis of the interrupter in various arcing time. - 电压跌落的发生、恢复时间的精确确定是获得跌落特性参数而首先要解决的问题。
The precise decision of the time that the voltage sag occurs and recovers will be the first problem to be solve for the sag characteristic parameters. - 目前动态电压恢复器(DVR)主要存在补偿电压时间有限,不能补偿电网电压浪涌,及检测电网电压波动并实时补偿电压等问题。
Now, the problems of existed DVR are that the compensation time is limited, can't compensate voltage surge and detect voltage change and compensate the change by real time.
