Abstract

The article discusses the model predictive control of a hybrid transformer (HT) with matrix converter (MC) together with the algorithm of turn-on and turn-off the compensator when it working with the power grid with small voltage changes from nominal values. The proposed solution of HT is used to resolve power quality issues and power flow control in the electrical power distribution system and can be mounted on the connection terminals of buildings. The advantages of predictive control are its very simple realization and possibility to optimize various predefined criteria. However, the proposed algorithm based on the measurement of rms phase voltage values allows for effective management of compensator operation. The operation of both algorithms has been verified in simulation studies.
用混合变压器补偿建筑物终端交流电压的变化
本文讨论了矩阵变换器混合变压器在与标称电压变化较小的电网工作时的模型预测控制及补偿器的通断算法。该方案可用于解决配电系统中的电能质量和潮流控制问题,并可安装在建筑物的接线端子上。预测控制的优点是它的实现非常简单,并且可以优化各种预定义的准则。然而,所提出的基于有效值相位电压值测量的算法可以有效地管理补偿器的运行。仿真研究验证了两种算法的有效性。
