Analysis of time varying load for minimum loss distribution reconfigurationKhan, Asif H. 06 June 2008 (has links)
A reconfiguration algorithm for electrical distribution system to reduce system losses is presented. The algorithm determines the switching patterns as a function of time. Either seasonal or daily time studies may be performed. Both manual and automatic switches are used to reconfigure the system for seasonal studies, whereas only automatic switches are considered for daily studies.
An algorithm for load estimation is developed. The load estimation algorithm provides load information for each time point to be analyzed. The load estimation algorithm can incorporate any or all of the following: spot loads, circuit measurements, and customer time-varying diversified load characteristics. Voltage dependency of loads is considered at the circuit level. It is shown that switching at the system peak can reduce losses but may cause a marginal increase in system peak. Voltage and current constraints are incorporated in the reconfiguration algorithm.
Data base tables and data structures used in the algorithm are described. Example problems are provided to illustrate results. / Ph. D.

Determining the recording time of digital media by using the electric network frequencyKantardjiev, Alex January 2011 (has links)
Authentication of recordings is an important task in forensic sciences. When processing audio or video material, some tasks might be related to determining whether or not the material has been edited or falsified in any way, or in other cases, to determine at what point in time a recording was made. The transition from analog to digital media has provided a solid foundation for the process of determining recording times by using the frequency variations in the electrical network, when interferences from the network are present in the investigated recording. This thesis describes a method of how to record the frequency of the electrical network in order to establish a reference database, evaluates several methods to isolate and extract the disturbances from recordings as well as suggests methods of how to search the database in order to locate the time of a recording. It is concluded, that each of the methods suggested has both advantages and disadvantages, depending on the state of the examined recording. Tests are also conducted in order to determine, whether or not, battery powered recording equipment is susceptible to recording the disturbances, or harmonics thereof, from electromagnetic fields near conducting wire or other electrical equipment. It is found that the fundamental frequency disturbance is usually difficult to detect, but also, that it is not uncommon that harmonics can be present in the recordings from the battery powered devices tested. Included in this thesis are also the results of the development of a graphical user interface for Matlab, where some of the features include the possibility to filter sound files, estimate frequency patterns and perform database searches, as well as the evaluation of a frequency analysis software. Both intended to serve as an aid for locating and extracting the disturbances of interest, as well as for finding the corresponding frequency patterns in the established database.
