Item Algorithms for detecting missing voltage and motor starting events(2016-08) Cho, Wanki; Santoso, Surya; Baldick, RossThe objective of this work is to develop algorithms to detect voltage variation events in power quality data and to figure out their characteristics. Voltage variation events covered in this work are missing voltage and motor starting events. The first part of this work describes the fundamental concept, characteristics and sources of voltage variation events. Next, this work describes the algorithms to detect voltage variation events. The verification of the algorithms is performed using simulated data from PSCAD/EMTDC and actual field data. The results show that the performance of the algorithms and the characteristics of voltage variation events are satisfactory. This work contributes to the development of detecting voltage variation events from a real distribution system and the analysis of voltage variation events.Item Modeling of a DC fuse for protection of semiconductor devices using PSCAD/EMTDC(2010-05) Devarajan, Bhargavi; Kwasinski, AlexisThis thesis presents a new simulation model for DC fuses used to protect semiconductor devices using PSCAD /EMTDC. The basic construction and operation of fuses is discussed, highlighting the difference between the operations of AC and DC fuses. The melting and arcing models of the fuse are implemented separately. The modeling concept is explained in detail and the model is validated with experimental results.Item PSCAD/EMTDC-Based Modeling and Analysis of a Microgrid with Renewable Energy Sources(2010-07-14) Chu, ZhengguoMicrogrid is a relatively new concept which has gained significant attention recently due to the increasing penetration of distributed energy sources. It brings many benefits to the traditional distribution system. Couples of microgrid testbeds in the forms of either hardware facilities or software simulation systems have been developed to study microgrid issues in many institutes throughout the world. In the work presented in this thesis, a microgrid system model in PSCAD/EMTDC was developed. The proposed microgrid system includes fundamental power system component models, two renewable energy source models (wind and solar) and one energy storage source model. Different case studies were conducted. The results from the simulation case studies showed that the proposed microgrid system in PSCAD had satisfactory performance under different scenarios with renewable energy sources. The proposed microgrid system model can be used for further research on microgrid issues.
