Abstract The requirement of a robust and adaptive control algorithm in active filters is inevitable nowadays. In this paper, an ADAptive LINEar neuron (ADALINE) based Least Mean Square (LMS) control algorithm is proposed for a three-phase-four-wire (3P4W) distribution power system under unbalanced loading conditions. The proposed controller has a unique inbuilt characteristic to extract the fundamental active positive sequence component from an unbalanced load current. Particularly, the control algorithm is intended to calculate an adaptive and suitable amplitude for the three-phase reference source currents which are used for the switching pulse generation in the subsequent steps. Moreover, the Distribution STATic COMpensator (DSTATCOM) is performed to eliminate harmonic contents of supply current and harmful excessive neutral current in the system. Further, the DC-link voltage is regulated in order to reduce the power loss across the DSTATCOM, and to attain a balanced, high-quality power availability at the Point of Common Coupling (PCC). The proposed system is accomplished in the MATLAB2014a/Simulink, and a low power rated 3P4W DSTATCOM prototype incorporating with the dSPACE1104 real-time environment to verify the proposed control algorithm.

ADALINE 最小均方算法在三相四线 DSTATCOM 中提高电能质量的实验验证

摘要 目前,有源滤波器需要鲁棒的自适应控制算法是不可避免的。在本文中,针对不平衡负载条件下的三相四线 (3P4W) 配电系统提出了一种基于自适应线性神经元 (ADALINE) 的最小均方 (LMS) 控制算法。所提出的控制器具有独特的内置特性,可以从不平衡负载电流中提取基本的有源正序分量。特别地,控制算法旨在计算用于在后续步骤中产生开关脉冲的三相参考源电流的自适应且合适的幅度。而且,配电静态补偿器 (DSTATCOM) 用于消除系统中电源电流的谐波含量和有害的过大中性线电流。此外,直流链路电压经过调节以减少 DSTATCOM 上的功率损耗,并在公共耦合点 (PCC) 处获得平衡、高质量的电源可用性。所提出的系统是在 MATLAB2014a/Simulink 中完成的,低功率额定 3P4W DSTATCOM 原型与 dSPACE1104 实时环境相结合,以验证所提出的控制算法。
