| 摘 要： | 提出了一种用于补偿不对称负荷产生的负序、零序分量并调整负荷母线电压，且适用于三根三线制和三相四线制系统的新型无功补偿器。该补偿器由用于补偿负序分量并调整负荷母线电压的三相电压型逆变器和用于补偿零序分五的单相逆变器组成。采用基于d－q变换的瞬时值逆变器输出电压合成方法和SPWM调制方式来实现装置的快速响应。

| Abstract: | This paper presents a new reactive power compensator to reduce the negative and zero sequence components of load currents and to improve the load bus power factor of unhalanced three - Phase three- wire and three-phase four- wire distribution feeders. The new compensator consists of a therr-phase voltage source inverters (to eliminate negative sequence current and adjust reactive power) and a single - phase voltage source inverters (to eliminate zero sequence current). The use of one way to Synthesis the output voltage of inverter based d-q commutation and SPWM results in a System with fast dynamic response. |
