Abstract

The interval type II fuzzy logic controller (IT2FL) is a recent artificial intelligent technology which is applied in many aspects of electrical power engineering and controlling strategies these days. The improving of Distribution Static Synchronous Compensator (DSTATCOM) control algorithms is still ongoing, because the control strategy of DSTATCOM device is considered as a decisive factor which affects the performance of DSTATCOM device in enhancing the quality of power in the distribution grids. The improving process focuses in two main aspects the DC capacitor voltage response to the control system and the mitigation of the harmonics which are produced by the controlled and uncontrolled rectified loads. In this paper, the interval type II fuzzy logic controller (IT2FL) based the Unit Voltage Template strategy (UVT) is examined by the MATLAB program with two different ranges of input signals, and compared with the type I Fuzzy logic controller (T1FL). The IT2FL based UVT shows promising results in improving the deformed shape of source current waves in comparison with the other controllers.

一类模糊逻辑转化为区间二类模糊逻辑的受控负荷单元电压模板

区间II型模糊控制器(IT2FL)是一种新兴的人工智能技术，目前已广泛应用于电力工程和控制策略的各个方面。配电静态同步补偿器(DSTATCOM)控制算法的改进仍在进行中，因为DSTATCOM设备的控制策略是影响DSTATCOM设备性能以提高配电网电能质量的决定性因素。改进过程主要集中在两个方面:直流电容电压对控制系统的响应以及受控和不受控整流负载产生的谐波的抑制。本文通过MATLAB程序对基于单元电压模板策略(UVT)的区间型模糊控制器(IT2FL)进行了两种不同范围输入信号的检测，并与I型模糊控制器(T1FL)进行了比较。与其他控制器相比，基于IT2FL的UVT在改善源电流波变形形状方面显示出良好的效果。
