This paper describes countrywide electrical power quality (PQ) assessments of the Turkish Electricity Transmission System through a genuine PQ database. The database stores the output of mobile PQ measurement systems which are established at 172 transformer substations of the transmission system. At 601 measurement points in these substations, which are potentially critical in terms of PQ, measurements are carried out by the mobile systems for a period of 1 week. PQ parameters defined in the IEC-61000-4-30 standard in addition to power values are calculated from acquired raw data by the mobile-monitoring system and the resulting data are transferred to the PQ database. The database, based on a novel PQ data model, enables its users to take PQ snapshots of the transmission system countrywide and can be accessed through several interfaces including a visual query interface, a natural language interface, and a map interface. The overall PQ status of the measured points, representing the characteristics of the transmission system, is assessed through these interfaces and problematic points are determined while deriving important conclusions about the transmission system's PQ behavior. Moreover, several novel PQ assessment methods are proposed and their applications on the PQ data are demonstrated especially through the map interface.

Enhanced Nationwide Wind-Electric Power Monitoring and Forecast System Terciyanli, Erman; Demirci, Turan; Kucuk, Dilek; Sarac, Maksut; ÇADIRCI, IŞIK; Ermiş, Muammer (2014-05-01) This paper describes an enhanced monitoring and forecast system for the electrical power generated from wind in Turkey. Wind power plant (WPP) owners, transmission system operator, distribution system operators, and renewable energy experts are the shareholders of this system. The developed monitoring and forecast system is composed of wind electricity analyzers and reference wind masts, one for each WPP, a Wind-Electric Power Monitoring and Forecast Center (WPMFC) equipped with database, data processing, a...
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...
National PQ monitoring network for Turkish electricity transmission system Demirci, Turan; Kalaycioglu, Alper; Salor, Oezguel; Pakhuylu, Serkan; Dagli, Mehmet; Kara, Tugberk; Aksueyek, Hasan S.; Topcu, Cigdem; Polat, Beyhan; Bilgen, Semih; SEZEN, UMUT; Cadirci, Isik; Ermiş, Muammer (2007-05-03) 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...
Mobile monitoring system to take nationwide PQ measurements on electricity transmission systems 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 ...
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...
