摘要

以补偿电压跌落的最大可持续补偿时间为控制目标，提出一种用于电压跌落补偿系统的新型时间优化控制策略。利用时间优化控制策略，在电路系统参数一定时，用较小的直流储能或较低的直流母线电压就能取得较大的持续补偿时间。同时，将时间优化控制策略与能量优化控制策略进行对比研究。研究表明，在一定情况下，运用时间优化控制策略能取得比运用能量优化控制策略更长的持续补偿时间。仿真结果很好地验证了理论分析。

Abstract

To maximize compensating duration during voltage sag， a new time optimal control strategy for voltage sag compensation is proposed. Compared with the traditional control strategies， the proposed strategy can be employed to control the DC link storage energy more effectively under the same condition. By the proposed time optimal control strategy， the maximum compensating time under the condition of lower DC link voltage or lower storage energy can be obtained. To verify the proposed strategy， the new time optimal control strategy and the energy optimal control strategy are compared. The simulation results show that compared with the energy optimal control strategy， under the same condition， longer compensating duration can be obtained by the proposed time optimal control strategy.
