Our Research Topics are bellow
System Components & Classification
Understanding the structure and function of Distribution Substations (for voltage step-down), Feeders (primary distribution lines), Distribution Transformers (step-down to utilization voltage), Distributors, and Service Mains (connection to the consumer).
Differentiating between systems based on voltage level (Primary vs. Secondary), current type (AC vs. DC), construction method (Overhead vs. Underground), and connection scheme (Radial, Ring/Loop, Interconnected).
Planning & Design
- Load Analysis & Modeling: Calculating and characterizing different types of loads (residential, commercial, industrial), and factors like Load Factor, Diversity Factor.
- Distribution System Design: Principles for optimal location of substations, determining feeder loading, and basic design practices for both primary and secondary systems.
- Conductors & Materials: Selecting appropriate conductors, insulators, poles/towers, and cables for various applications.
System Analysis & Performance
- Voltage Drop & Power Loss: Calculating and analyzing voltage variations and power losses across feeders and distributors, which are critical for system efficiency and power quality.
- Power Factor Correction: Methods and economics of installing capacitors (shunt and series) to improve the system power factor and reduce losses.
- Voltage Control & Regulation: Techniques like tap-changing transformers and voltage regulators to maintain voltage within acceptable limits for the customer.
Protection & Reliability
- Distribution System Protection: Identifying common faults (short circuits, overloads) and the design and coordination of protective devices.
- Protective Devices: Principles of operation for Fuses, Circuit Breakers, Reclosers, and Sectionalizers.
- Coordination: Ensuring that protective devices operate selectively to isolate only the faulted section while minimizing the impact on the rest of the system.
- Reliability: Analyzing system reliability, including factors like Mean Time between Failures (MTBF) and ensuring continuity of service.
Modern Systems & Automation
- Smart Grid Technology: Integrating advanced metering infrastructure (AMI), sensors, and communication systems into the distribution network.
- Distributed Generation (DG) Integration: Managing the challenges and opportunities of connecting renewable energy sources (solar, wind) and other DG units to the traditional grid.
- Distribution Automation: Implementing Supervisory Control and Data Acquisition (SCADA) and Advanced Distribution Management Systems (ADMS) for remote monitoring, control, and fault location/isolation/restoration (FLISR).
