The conventional method is expensive and time consuming as well as it requires man power for monitoring and data collection of the consumers which may also lead to human errors. The proposed GSM based system integrates digital energy meters installed at consumer unit with an electric supply companies to monitor, profile and control energy flow with the help of Graphical User Interface (GUI). In this two-way communication system, the GSM network is utilized to profile the energy flow with the help of SMS to the energy supplier and showing it on the monitor of the energy supplier using the GUI and can also communicate with the user via SMS. Relay circuit and LCD display is provided to update information like Voltage, Current, Units and billing or sudden power cut to the energy supplier company and is displayed on GUI. Nowadays the main problem in energy supply is that of power theft being done on various scales. Our system can also send an alert to the energy supplier in case of any power theft at the consumer side and cutoff the supply automatically until the power theft is not being cleared. This research highlights the general theory of energy metering system and focuses on our user friendly low power energy metering system design, implementation, power theft control and results. 2018-01-01T00:00:00Z http://hdl.handle.net/123456789/7811 Application of AAA for Optimized Placement of UPFC in Power systems Muhammad Zahid; Jinfu Chen; Yinhong Li; Ghulam Mohy-ud-din; Asad Waqar This paper suggests an innovative scheme for examining the optimized power flow problem based on optimum position and configuration setting of Unified power flow controller (UPFC) by utilizing the artificial algae algorithm (AAA) technique. Flexible AC Transmission system (FACTS) devices have the ability to provide flexibility and control for complex power transmission systems. Unified power flow controller is proficient fellow of FACTS which has the capacity to regulate power system constraints (line impedance, voltage profile and phase angle). The core aim of this research is to solve the optimal power flow problem by curtailing or removing the over-loaded of lines and the bus voltage violations created under contingency circumstances. In first round, the contingency analysis and raking process is performed while taking the transmission line loading and voltage violations as a decision parameter (DP=NOVL+NVVB). Afterwards, the proposed technique (AAA) is exercised to discover the solution of optimal power flow issue based on optimal location of UPFC with its parameters setting under the generated single contingency of line scenarios. The simulations studies are practiced on IEEE standard benchmark-5 bus system to check the performance of this novel scheme. 2018-01-01T00:00:00Z http://hdl.handle.net/123456789/7812 Comparison of High Frequency Filters for Power System Regulation Badar Ali; Muhammad Umair Alam; Zeashan Hameed Khan; Asad Waqar; Jehanzeb Ahmad This paper presents the simulation of various high frequency filters including single and double loop feedback controller based LCL filters, Zero phase filter, Savitzky-Golay filter and cascaded low-pass IIR filters utilized for power regulation from the smart grid. Power output from renewable sources comprises of DC power output. Such power needs power electronics converters to transform the output from various renewable sources of energy into alternating (AC) power having fixed frequency e.g. 50/60 Hz, so that the power can be consumed at utility level. Such conversion should not surpass the total harmonic distortion (THD) permissible limit. In order to filter out THD from such systems, various filters have been implemented in LabVIEW to compare the results. 2018-01-01T00:00:00Z http://hdl.handle.net/123456789/7813 Real-time Control of a Mobile Robot using Electrooculogram based Eye Tracking System Uzair Hassan; Hassam Mughal; Inamullah Mohsin; Zeashan Hameed Khan This paper describes a system architecture starting from the sensor design to the algorithm implementation to control a mobile robot using electrooculogram based eye tracking system. Various methods exist to control external devices with muscle movements, Electrocardiogram (ECG) or Electroencephalogram (EEG). The proposed system works with Electrooculogram (EOG) by sensing eye movement and is found beneficial for paraplegic/quadriplegic patients who can get assistance from a 2-DOF robotic arm to perform their daily tasks. This low cost design can be easily implemented on an embedded robotic platform for implementation in various domains. 2018-01-01T00:00:00Z
