This paper describes mobile power quality monitoring systems developed to carry out extensive power quality (PQ) measurements nationwide, in addition to instrumentation and measurement technologies used in those systems. The developed systems have been used to measure the PQ of the Turkish Electricity Transmission System, which is among the largest transmission systems in Europe. To make trouble-shooting studies at the problematic measurement points in terms of PQ different measuring instruments and a wide range of PQ analysis methods from raw data acquisition to PQ event detection have been achieved depending on the nature of the problem, thanks to the flexible signal processing algorithms developed. Being an essential issue in the evaluation of PQ at various points of the electricity transmission network, time synchronization of mobile PQ monitoring systems has been applied using different techniques. Electromagnetic immunity of the system has been tested and reported. Based on the proposed instrumentation and measurement technologies, PQ of the 205 measurement points has been assessed all over the country. In order to exhibit the capabilities and usefulness of the mobile monitoring system developed, sample measurement results are given in the paper. Guidelines of instrumentation and measurement technologies are presented for other researchers who would like to build distributed PQ measurement systems.

Mobile monitoring system to take PQ snapshots of Turkish electricity transmission system
Oezdemirci, E.; Akkaya, Y.; Boyrazoglu, B.; Buhan, S.; Terciyanh, A.; Uensar, O.; Altintas, E.; Haliloglu, B.; Acik, A.; Atalik, T.; Salor, O.; Demirci, T.; Cadirci, I.; Ermiş, Muammer (2007-05-03)
This work is devoted to taking nationwide power quality (PQ) snapshots of the Turkish Electricity Transmission System, via field measurements carried out by application speck mobile monitoring equipment. This project is carried out as a subproject of the National Power Quality Project of Turkey, and is aimed at investigating the general status of electric power quality and reactive power flows in the Electricity Transmission System all over the country. Critical points will then be selected to place permane...

In this paper a nationwide power quality monitoring system, which computes and collects PQ parameters and the required waveforms at a power quality monitoring center for both the purposes of early warning and later analysis of power quality of the whole transmission system, is presented. The system consists of three basic units: PQ monitors connected to various transformer substations all over the country; a national PQ monitoring center which communicates with all PQ monitors regularly, receives PQ data an...
Multipurpose Platform for Power System Monitoring and Analysis With Sample Grid Applications
Atalik, Tevhid; ÇADIRCI, IŞIK; Demirci, Turan; Ermiş, Muammer; İNAN, TOLGA; Kalaycioglu, Alper Sabri; Salor, Ozgul (2014-03-01)
This paper is devoted to the design and implementation of a multipurpose platform (MPP) for power system monitoring and analysis. This MPP is a novel device, which combines the abilities of a power quality (PQ) analyzer, an event logger, a synchronized phasor measurement unit, and an interarea oscillation identifier, all in one device. The multiple functions of the proposed MPP can serve the needs of the power system operators (SOs) as a wide-area monitoring system to observe the states and stability of the...
Linearization of RF power amplifiers with memoryless baseband predistortion method
Kolcuoğlu, Turusan; Demir, Şimşek; Department of Electrical and Electronics Engineering (2011)
In modern wireless communication systems, advanced modulation techniques are used to support more users by handling high data rates and to increase the utilization efficiency of the limited RF spectrum. These techniques are sensitive to the nonlinear distortions due to their high peak to average power ratios. Main source of nonlinear distortion in transmitter topologies are power amplifiers that determine the overall efficiency and linearity of the transmitter. To increase linearity without sacrificing effi...
Highly Integrated 3 V Supply Electronics for Electromagnetic Energy Harvesters With Minimum 0.4 V-peak Input
Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2017-07-01)
This paper presents a self-powered interface enabling battery-like operation with a regulated 3 V output from ac signals as low as 0.4 V-peak, generated by electromagnetic energy harvesters under low frequency vibrations. As the first stage of the 180 nm standard CMOS circuit, harvested signal is rectified through an ac/dc doubler with active diodes powered internally by a passive ac/dc quadrupler. The voltage is boosted in the second stage through a low voltage charge pump stimulated by an on-chip ring osc...
