摘要

介绍了中性点箝位(NPC)多电平电压源逆变器(VSI)无功、有功控制的实时建模与仿真。基于VSI末端的电流,实现了一种解耦控制方案。在OPAL-RT和Speedgoat数字模拟器上进行了仿真。此外,在实验基准中评估了全闭环模型对有功功率和无功功率(P和Q)变化的阶跃响应。实时建模和原型显示了全闭环控制的能力,以开发和验证在电网上实现的实际电力电子设备。

Real-time Closed-loop PQ Control of NPC Multi-level Converter Using OPAL-RT and Speedgoat Simulators
This paper introduces real-time modeling and simulation of the reactive and active power control of Neutral-Point Clamped (NPC) multilevel Voltage Source Inverter (VSI). A decoupled control scheme has been implemented based on the current at the terminal of the VSI. The simulation is performed on OPAL-RT and Speedgoat digital simulators. Further, full closed-loop models are evaluated in an experimental benchmark for the step response of active and reactive power (P and Q) changes. The real-time modeling and prototyping shows the capability of fully closed-loop control to develop and validate actual power electronic devices implemented on the power networks.
