The Mathematical Model

In order to improve the power quality problems caused by electric vehicle charging equipment, this paper put forward the research on Application of Unified Power Quality Controller (UPQC) in the charging field. Based on the mathematical model of UPQC, current control unit with state feedback single loop PI controller and voltage control unit based on dual PI loop controller are designed. Based on the mathematical model, the design reference parameters are derived. Finally, a UPQC prototype is developed and experiment is carried out, results show that UPQC has good application prospect in the field of electric vehicle charging.

Traction System

Advancement and extensive use of power electronic devices such as, fast switching uncontrolled/controlled convertors, invertors and cyclo-converters, high voltage power convertors used in HVDC, high voltage drives in traction system, arc furnaces, modern single phase electronic equipments like Compact Fluorescent Lamps (CFLs), Uninterruptible Power Supply (UPS), Personal Computers (PCs), printers, battery chargers, fax machines, photocopiers etc. creates power quality problems, the measure of it was voltage and current harmonics, poor power factor, imbalance, reactive power compensation, voltage regulation etc. Ideally power system network must be electrically clean, harmonics free, balanced, sinusoidal with unity power factor and regulated. This work deals with the performance of Series-Shunt Power Quality Compensator (SSPQC) under distorted source voltages and load currents. In this work a novel control strategy of Synchronous Reference Frame (SRF) used to extract the fundamental reference voltage component and the ICC based technique used to predict source current which simplifies the computation and amplifies the system performance.

Research On Application

At present, the situations of long period independent operation of each kind of distribution and consumption management system and lack of effective integration, it obstructed the inter-departmental coordination of business operations. According to IEC61968, the paper proposed a smart distribution and consumption integrated management system that integration of existing systems at the distribution and consumption side. The system can solve the problem of information islands. With the scope of the power system data acquisition continues to expand, in the future need mass data storage and analysis capabilities, it is insufficient of the existing storing and information-processing platform of the power system, the cloud storage based on Hadoop can solve the problem. The Experiments show that cloud storage based on Hadoop clusters has characteristics of high throughput rates and high transmission rate, which can meet the mass data storage access requirements of the smart distribution and consumption integrated management system.
