In this study, a nationwide real-time monitoring system has been developed to monitor all electrical quantities and power quality (PQ) parameters of the electricity transmission network including its interfaces with the generation and distribution systems. The implemented system is constituted of extended PQ analysers (PQ(+) analysers), a national monitoring center for power quality (NMCPQ), and the PQ retrieval and analysis software suite. The PQ(+) analyser is specifically designed for multipurpose usage such as event recording and raw data collection, in addition to the usual PQ analysis functions. The system has been designed to support up to 1000 PQ(+) analysers, to make the electricity transmission system and its interfaces completely observable in the future. The remote monitoring, analysis and reporting interface, the map-based interface, and the real-time monitoring interface, as well as the Web applications run on the NMCPQ servers, can be accessed by the utility, large industrial plants, distribution companies and researchers, to the extent of the authorisation given by the transmission system operator. By activating sufficient number of analogue and digital outputs of PQ+ analysers, and equipping the NMCPQ with necessary hardware, analysis and decision making software, the proposed system can serve as an advanced supervisory control and data acquisition system in the future. The proposed monitoring concept can be extended to serve the needs of the modern electricity markets, by making various regulations, codes and instructions implementable.

Salor, Oe; Buhan, S.; Uensar, Oe; Boyrazoglu, B.; Altintas, E.; Atalik, T.; Haliloglu, B.; Inan, T.; Kalaycioglu, A.; Terciyanli, A.; Acik, A.; Demirci, T.; Oezdemirci, E.; Cadirci, I.; Ermiş, Muammer (2009-05-01)
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 ...
Transformers Analysis Design and Measurement
Ertan, Hulusi Bülent (CRC press, 2012-01-01)
Recent catastrophic blackouts have exposed major vulnerabilities in the existing generation, transmission, and distribution systems of transformers widely used for energy transfer, measurement, protection, and signal coupling. As a result, the reliability of the entire power system is now uncertain, and many blame severe underinvestment, aging technology, and a conservative approach to innovation. Composed of contributions from noted industry experts around the world, Transformers: Analysis, Design, and Me...
Fully Integrated Autonomous Interface With Maximum Power Point Tracking for Energy Harvesting TEGs With High Power Capacity
Tabrizi, Hamed Osouli; Jayaweera, Herath M. P. C.; Muhtaroglu, Ali (Institute of Electrical and Electronics Engineers (IEEE), 2020-05-01)
In this article, a novel fully autonomous and integrated power management interface circuit is introduced for energy harvesting using thermoelectric generators (TEGs) to supply power to Internet of Thing nodes. The circuit consists of a self-starting dc & x2013;dc converter based on a dual-phase charge pump with LC-tank oscillator, a digital MPPT unit, and a 1-V LDO regulator. The novel maximum power point tracking (MPPT) algorithm avoids open-circuit state, and accommodates varying input power and ultra-lo...
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...
Design and Performance Analysis of a Grid Connected PWM-VSI System
Kantar, Emre; Usluer, S. Nadir; Hava, Ahmet Masum (2013-11-30)
Pulse-width modulation (PWM) voltage source inverters (VSIs) are favorable interface devices to the power grid for renewable energy systems. This paper deals with the design of the LCL-filter and inverter for the grid-connected VSI. A complete design procedure for both reactive and passive components of LCL-filter is demonstrated with a new iterative approach in selection of the filter inductors. The design process for a two-level VSI is clearly illustrated through an example and the dynamic response is inv...
