分析了串联型电能质量调节装置（series power quality regulator, SPQR）完全补偿策略的最优补偿目标，提出了SPQR在其极限输出电压约束下的2步应对措施，可以使装置在补偿能力范围内尽可能地实现完全补偿策略的最优目标。采用对SPQR最优补偿目标的解析式分析与影响关系曲线分析相结合的方法，得到了装置最优补偿目标受到系统电压幅值、系统电压相位跳变以及装置极限补偿电压3方面因素影响的结论，最后给出了SPQR在极限补偿电压约束下实现最优补偿目标的系统电压变化范围，分析结果将有助于SPQR补偿策略的设计及工程实践。

Characteristic of Pre-sag Voltage Compensation Strategy for Series Power Quality Regulator

A ＂two steps measures＂ for series power quality regulator（SPQR） in its limitation voltage is proposed based on the analysis of the pre-sag voltage compensation strategy＇ s optimal compensation aim. The proposed measures can make the equipment realize the optimal compensation aim with its fullest ability. The analysis formula and influence curves of optimal compensation aim show that the equipment＇ s optimal aim is influenced by three factors which include the limitation value of the compensation voltage, magnitude and phase of the source voltage. In addition, the source voltage variation scope which can realize the optimal compensation aim in limitation voltage is given. The analysis results will be useful to compensation strategy design and engineering practice.
