新型综合配网调控装置及其应用
|
摘要
由于配电网的结构复杂以及入网设备的多样化,电力系统的电能质量问题逐渐显露出来。电能质量问题涵盖广泛,既涉及电压合格率,又关系谐波含量。这种情况下,必须采用相应的电能质量调节装置进行改善。为了解决配网质量问题,本文从谐波消除、基波补偿等方面综合研究,提出一种新的配网综合调控装置,给出各部分硬件电路和控制策略。通过在贵州省安顺市的实际运行使用,验证了该装置在完成三相不平衡电流补偿、无功补偿、电压平衡及节能减耗等方面具有良好的性能,值得进一步推广。
Due to the complex structure of the distribution network and varieties of network equipment, power quality problems of electric power system have been exposed gradually. The issue of power quality covers a wide range. It contains both voltage qualification and harmonic content. In this case, a power quality conditioner must be used for improvement. In order to solve problems of distribution network power quality, this paper proposes a new combined power quality conditioner in distribution network, based on harmonic elimination and fundamental wave compensation. It gives hardware circuit and control strategy. The actual operation of the device, in anshun city guizhou province, proves that the device has good capabilities in the completion of three-phase unbalanced current compensation, reactive power compensation, voltage balance, energy saving and so on. In result,it's worth further promotion.
