Multi-source Partial Discharge Signals Discrimination by Six Bandpass filters and DBSCAN Clustering
Anşin, Berfin (2018-01-01)
Partial discharge (PD) signals generated by defects in a transformer insulation can be captured through measurement instruments and they may be used, after preprocessing, to discriminate the PD Sources. Some of the artificial defect models, such as: corona, internal cavity and surface discharge in air are developed in the laboratory. These defect models are put in parallel under a high voltage stress. The PD signals stemmed from these sets of multiple PD sources are captured. In this paper six bandpass filt...
Multi-hazard reliability of electric power transmission networks with spatially correlated components
Altay, Umut; Dener Akkaya, Ayşen.; Department of Statistics (2019)
Many network systems such as, gas and water pipelines, power transmission and distribution systems, highways and communication systems extend spatially over large geographical regions. Such network systems are composed of interconnected components which form paths. Correlation, resulting from similar topography, soil conditions as well as external loading due to the same environmental factors, between the behaviour of those elements should be taken into consideration and be quantified. In this respect the s...

Multi-item inventory-routing problem for an FMCG company
Zerman, Erel; Kırca, Ömer; Department of Industrial Engineering (2007)
In this study, inventoryrouting system of a company operating in Fast Moving Consumer Goods (FMCG) industry is analyzed. The company has decided to redesign distribution system by locating regional warehouses between production plants and customers. The warehouses in the system are all allowed to hold stock without any capacity restriction. The customers are replenished by the warehouse to which they have been assigned. Customer stocks are continuously monitored by the warehouse and deliveries are to be sch...
Multi-Period Reactive Power Optimization for Determination of Switch Statuses of Shunt Elements and Voltage Setpoints of Power Plants
Elma, Ismail; Güven, Ali Nezih (2021-01-01)
© 2021 Chamber of Turkish Electrical Engineers.Transmission system operators (TSOs) need to control voltages along the grid to have an economic and reliable system operation. Due to fixed and operational costs of switching equipment of shunt elements, TSOs are expected to minimize the number of switching operations of these devices. The purpose of this study is to optimize reactive power flows so as to have minimum transmission losses and number of switching operations of controllable shunt elements within ...
