摘　　要：为了减轻电能质量问题对电机的影响,提高电机运行的稳定性与可靠性,对电能质量控制技术进行了研究。介绍了统一电能调节器的基本结构与工作原理,提出了基于广义瞬时无功功率理论的检测方法和控制策略,详细分析了补偿信号的计算方法。仿真结果表明,该技术不仅可以减轻电机对电网的污染,而且能够改善电网的电能质量,为电机提供稳定、可靠的绿色电源。To reduce power quality problem affect of electric motor, to boost motor＇ s running stability, running reliability, the power quality control technology is researched. The basic configuration and working principle of the unified power quality controller are introduced. The testing method based on generalized theory of the instantaneous reactive power and control strategy is proposed. The algorithm of compensation signal is analyzed in detail. The simulation results show that this technology not only reduce the non-linear electric machine to pollute the power grid, but also improve the power quality of power grid, to provide electric machine equipment with stable, reliable green power supply.
