摘要

三电平T型并联有源电力滤波器3LT²SAPF（three-level T-type shunt active power filter）被广泛应用于改善非线性负载下的电网电能质量，其抑制谐波、补偿无功功率的性能和可靠性受到了广泛关注，同时模型预测控制MPC（model predictive control）能够实现多目标优化。而一旦由于温度变化等原因导致参数不匹配，MPC系统的输出性能将严重恶化，甚至可能危及系统稳定性。此外，当电路关系未知、无法建立预测模型时，MPC控制器将不再适用。为了解决这些问题并增强系统鲁棒性，提出了1种线性拟合无模型顺序预测控制方法。首先分析了电流预测的线性拟合方法原理，其次建立了用于谐波电流跟踪的各开关矢量的电流误差矩阵，最后设计了中性点NP（neutral point）电压和直流母线电压的成本函数。在不同场景下的大量实验验证了所提方法的正确性和有效性。

Abstract

收起

The three-level T-type shunt active power filter (3LT²SAPF) has been widely used to improve the power quality of power grid under nonlinear load, and its harmonic suppression and reactive power compensation performance and the corresponding reliability have attracted wide attention. Meanwhile, model predictive control (MPC) can achieve multi-objective optimization. However, once the parameter mismatch occurs due to reasons such as changes in temperature, the output performance of an MPC system will be seriously deteriorated. This may even may endanger the system stability. Additionally, when the circuit relation is unknown, the establishment of a predictive model is not available, and the MPC controller will not be applicable. To solve these problems and enhance the robustness of the 3LT²SAPF system, a linear fitting sequential model-free predictive control method was proposed. First, the principle of linear fitting method for current prediction was analyzed. Second, a current error matrix for each switching vector was established, which can be used for harmonic current tracking. Finally, the cost functions for neutral-point (NP) voltage and DC-bus voltage were designed. The results of numerous experiments under different scenarios verified the correctness and effectiveness of the proposed method.
