Abstract

Power quality generally refers to the adequacy of the power system’s voltage, current, and frequency. Typically, any related distortion can reflect several forms of negative impacts that might affect the system equipment operation. Power electronics-based apparatus within telecommunication data center facilities are generating such harmonic distortion causing well-known several power quality issues. Furthermore, such harmonics can also propagate back to the electrical grid increasing the risk of sensitive equipment failure and maloperation. In this paper, real measurement results of current and voltage waveforms along with their total harmonic distortion (THD%) investigations of typical telecom data centers are presented. In addition, a capacitor-less distribution static synchronous compensator (D-STATCOM) is proposed to improve the degraded levels of power quality indices. Simulation results using MATLAB/Simulink are presented in this paper confirming the effectiveness of the capacitor-less D-STATCOM device in providing dynamic compensation regarding power factor correction and harmonic distortion reduction.

无电容D-STATCOM在典型电信数据中心电能质量提升中的应用

电能质量一般是指电力系统的电压、电流和频率是否充足。通常，任何相关的失真都可能反映出可能影响系统设备运行的几种形式的负面影响。电信数据中心设施中基于电力电子的设备正在产生这种谐波失真，从而引起众所周知的一些电能质量问题。此外，这种谐波还可以传播回电网，增加敏感设备故障和误操作的风险。本文介绍了典型电信数据中心电流、电压波形的实测结果及其总谐波失真(THD%)的研究。此外，提出了一种无电容分布静态同步补偿器(D-STATCOM)，以改善电能质量指标的退化程度。本文利用MATLAB/Simulink进行了仿真，验证了无电容D-STATCOM器件在功率因数校正和谐波失真降低方面的动态补偿效果。
