摘要
针对中国农村电网无功严重不足的现状,研发了一款新型动态无功补偿成套装置,该装置具有结构简单、成本低、体积小和运行可靠等优点。通过长期挂网试验表明,该无功补偿成套装置能够快速跟踪负载无功功率的变化,动态投切电容,同时可以很好地防止过补偿和投切振荡,有效地抑制电压闪变,降低了线损和变压器损耗,特别适合我国农村电网无功补偿的实际需求。
Considering the shortage of reactive power in rural power grids,a reactive power compensation equipment was designed.It had the advantage of simple structure,low cost,small volume and reliable running.The result of experiment indicated that the device responded rapidly to variety of percussive load.It could prevent overcompensation and withhold switching oscillation,reduce loss and upgrade power supply quality.Due to its advantages of rapid response,convenient operation,high reliability,and non-impulse,the device had a promising application prospect.
