Using Grey Target Theory for Power Quality Evaluation Based on Power Quality Monitoring Data
نویسندگان
چکیده
Smart grid puts forward higher requirements for power quality. Power quality evaluation can provide a decision-making basis improvement. Based on monitoring data, grey target method is proposed evaluation. The composed of standard and data to be evaluated. Combining with the characteristics each index, center whole system found. Then, evaluated mode are compared analyzed construct correlation difference information space. Finally, coefficient degree calculated realize comprehensive quality, grade obtained. Compared results existing literature, effectiveness verified, which shows that theory reasonable in

15 صفحه اولPower Quality Monitoring using PMU
Voltage sags are the most common power quality disturbance usually associated with power system faults, which can cause huge economic loss, making it the focus of emerging research. The proposed voltage sag detection technique for a single-line-to-ground (SLG) fault is presented using the PMU measurement data for improving the power quality. Various voltage sag detection techniques have been di...

متن کاملPower Quality Improvement by Unified Power Quality Conditioner Based on CSC Topology Using Synchronous Reference Frame Theory
This paper deals with the performance of unified power quality conditioner (UPQC) based on current source converter (CSC) topology. UPQC is used to mitigate the power quality problems like harmonics and sag. The shunt and series active filter performs the simultaneous elimination of current and voltage problems. The power fed is linked through common DC link and maintains constant real power ex...
متن کاملMultifunction Power Quality Monitoring System
In this paper a new power quality monitoring (PQM) system for detection and classification of power quality voltage disturbances is presented. The implementation of the proposed PQM system in a graphical user interface (GUI) is also presented. The wavelet transform (WT) is used for de-noising and detection of the disturbances on power voltage line. Detected disturbances are separated using bina...
