The effects of power quality (PQ) issues in a distribution feeder occur due to abnormal load condition. In this paper, first, the real time PQ issues in an 11 kV/440 V distribution feeder are measured and analyzed by PQ analyzers. The sudden load fluctuations in the distribution system result in different PQ issues such as voltage sag/swell, transient, flicker and harmonics. Then, an improved interactive distribution static synchronous compensator (D-STATCOM) is installed in distribution feeder to mitigate the PQ issues. A novel control algorithm will operate the interactive D-STATCOM in voltage control mode (VCM) or current control mode (CCM). At normal operating conditions, the D-STATCOM operates in CCM, during abnormal condition the D-STATCOM will operates in VCM to mitigates the PQ issues. The D-STATCOM is modeled and simulated in MATLAB-SIMULINK environment. The field programmable gate array (FPGA)-based laboratory prototype D-STATCOM has been developed to validate the function of the controller.

使用配电静态同步补偿器实时评估 11 kV/440 V 配电馈线的电能质量问题

配电馈线中电能质量 (PQ) 问题的影响是由于异常负载情况而发生的。在本文中,首先,通过 PQ 分析仪测量和分析 11 kV/440 V 配电馈线中的实时 PQ 问题。配电系统中突然的负载波动会导致不同的 PQ 问题,例如电压骤降/骤升、瞬态、闪烁和谐波。然后,在配电馈线中安装改进的交互式配电静态同步补偿器(D-STATCOM)以减轻 PQ 问题。一种新颖的控制算法将在电压控制模式 (VCM) 或电流控制模式 (CCM) 下操作交互式 D-STATCOM。在正常运行条件下,D-STATCOM 以 CCM 运行,在异常条件下,D-STATCOM 将运行在 VCM 中以减轻 PQ 问题。D-STATCOM 在 MATLAB-SIMULINK 环境中建模和仿真。已经开发了基于现场可编程门阵列 (FPGA) 的实验室原型 D-STATCOM 来验证控制器的功能。
