三相电压型PWM整流器MPDPC的鲁棒性分析
The Robustness Analysis of Model Predictive Direct Power Control
本文在三相电压型PWM整流器传统模型预测直接功率控制(model predictive direct power control，MPDPC)的基础上引入延时补偿控制，得到一种改进MPDPC。为了探究改进MPDPC和传统MPDPC的鲁棒性及其鲁棒性主要受哪些参数影响，本文通过计算改进MPDPC和传统MPDPC在不同负载功率下分别取不同滤波电感值、滤波电阻值时系统的视在功率偏差及网侧电流畸变率。对计算结果进行分析，表明MPDPC的鲁棒性主要受滤波电感影响，而且改进MPDPC的鲁棒性优于传统MPDPC。该研究对MPDPC系统参数的选取、提高系统性能等，有一定的参考价值。
英文摘要:
This paper proposed an improved model predictive direct power control (MPDPC) of three-phase voltage sourced PWM rectifiers that introducing delay compensation control based on conventional MPDPC. In order to study the robustness and its robustness is mainly influenced by which parameters of improved MPDPC and conventional MPDPC, this paper calculated deviation of apparent power and harmonic spectrum of grid current of improved MPDPC and traditional MPDPC under different load power with different filtering inductance, filter resistance, respectively. Analysis of the calculation results, it shows that the robustness of MPDPC is mainly affected by the filter inductance, and the robustness of improved MPDPC is superior to traditional MPDPC.The study of MPDPC are good for selection of system parameters, improving system performance, etc., it have some reference value.
